German impact crusher processes Turkish perlite for Spanish and Italian fruit juice industry
are now processing two different types of perlite for the fruit juice industry using a BHS-Sonthofen PB 0806 impact crusher – the first time the machine has been used for this purpose
as well as previous experience with BHS machines gave Imerys the confidence to make this unusual choice
As a world leader in mineral-based specialties for industrial use
Imerys are experts in producing a wide variety of performance materials
their Harborlite Aegean subsidiary processes two types of amorphous volcanic glass
which is extracted from a quarry in Izmir province
The end product is used as a filtration medium by the Italian and Spanish fruit juice industries
one of the crushers in Harborlite Aegean’s plant in Dikili needed replacement
The old Turkish impact mill had reached the end of its service life and could no longer produce the required 35mm grain size
so Imerys decided to contact BHS-Sonthofen
BHS had recently delivered an RSMX rotor centrifugal crusher to another Imerys plant in Teutschenthal
to process highly abrasive aluminium oxide
The machine proved to be a reliable choice with low wear costs
and the technology and service from BHS-Sonthofen convinced Imerys that the German manufacturer would be best placed to replace the Turkish perlite crusher too
After an initial assessment of the requirements
BHS and Harborlite Aegean decided that a PB 0806 impact crusher with an output of 50 tonnes/h would be the ideal choice for the task
even though the BHS machine had never been used in this application before
The opportunity to thoroughly test the machine’s capabilities at the BHS Test Centre in Sonthofen boosted the team’s confidence
both varieties of the original materials were transported to Germany – one of them a pre-crushed perlite that was to be reduced from 0–90mm to a target size of 0–35mm
and the other a pre-crushed fraction from 0–300mm
‘Running tests with original material is a standard procedure here at BHS-Sonthofen,’ explained project manager Hans Traut
we make sure the machine is the best choice for the client
The tests also ensure optimal machine configuration for minimal wear and help us to adjust the machine so that the processed minerals match the client’s crushing requirements.’
The tests confirmed the experts’ recommendation
with the impact crusher proving to be a particularly economical solution for the fine crushing of perlite
Its maintenance-friendly design and adjustable gap width offer a key advantage for Harborlite Aegean
ensuring consistent product quality with low-maintenance costs
The Turkish company successfully installed the machine in late December 2021
plant and mine manager at Harborlite Aegean
said: ‘The impact crusher from BHS-Sonthofen proved to be a perfect fit for our plant and has been running smoothly since production started in January.’

the BF 350-255 filter plant is the largest that BHS has ever built
The BF 350-255 indexing belt filter will process up to 5000 kg of fibrous plant waste hourly
extracting recoverable liquid components generated in a previous production process
The filtrate is used for the manufacture of basic chemicals
the customer had initially envisaged a multi-stage process with a sequence of consecutive screening and filtration steps and with the solids being resuspended several times
BHS-Sonthofen proposed an indexing belt filter with a single process step
The simpler process allows greater concentration of the reusable substances
which means less energy is required for extracting the substances at a later stage
BHS-Sonthofen received the order in December 2015
and supplied the filter plant in spring 2016
Rotor impact mill and control system from a single source boosts productivity and efficiency
GERMAN building materials suppliers Dachser Fertigbeton-Kieswerke are currently expanding and optimizing their gravel plant in Türkheim by integrating a second RPM 1113 rotor impact mill from BHS-Sonthofen (BHS)
BHS supplied the complete control system to ensure seamless co-ordination of the two machines
making the plant easier to operate and increasing productivity and efficiency
Dachser have been reliably supplying numerous construction projects with building materials such as ready-mixed concrete
excess gravel is used to produces a high-quality 0-4mm sand for concrete production
‘Since we blend the crushed sand with natural sand
the resulting grain shape must be as close as possible to that of natural sand,’ explained Michael Zacher
this task was accomplished using rod mills
these proved to be energy intensive at low throughput rates.’
a BHS-Sonthofen RPM 1513 rotor impact mill has been crushing the material to the required particle size
This high-performance vertical-shaft impact mill
which is employed by Dachser in a customized configuration
is particularly suitable for crushing all low-to-medium-abrasive minerals
the company decided to further expand its plant in early 2023
Based on the positive experience with BHS-Sonthofen
outdated rod mill with a new BHS rotor impact mill
Dachser opted for a bottom-mounted drive for easier maintenance access
elevated machine housing with optimized flow performance
BHS carried out the project and commissioned the machine in the spring of 2023
This machine’s housing is a special version of the standard model with two enlarged openings in the discharge area
which allow for faster discharge of both crushed material and air
A downward-facing flanged motor was installed to provide more space for operation on the platform
The functionality of the RPM 1113 allows significantly higher throughput while consuming less energy compared to the rod mill
who is responsible for building materials machinery sales in the region
highlights that alternating right and left operation of the machine maximizes the utilization of the components used in this series
the cost-benefit ratio of the rotor impact mill far surpasses that of a rod mill
It offers a very high degree of crushing and delivers excellent cubic sand with a high proportion of fines and round corners.’
the mill is predominantly used to produce sand for the concrete
BHS-Sonthofen also provided the complete control system for the two rotor impact mills
customized specifically for Dachser’s needs
This includes powerful frequency converters for energy-efficient operation of the machines and a state-of-the-art user interface featuring touch screens
something that is particularly sought after,’ said Mr Zacher
summarizing the advantages of the two plants
‘Having both the plant and control system from a single source has streamlined installation and daily operations significantly.’
German specialists in solid-liquid filtration
recently analysed a food additive manufacturer’s filtration process and suggested rotary pressure filters as an alternative to the company’s existing three peeler centrifuges
The centrifuges were being used in a single production step and the manufacturer planned to replace them with three new
the company asked BHS-Sonthofen to take a close look at the process step itself
BHS-Sonthofen found that the use of a rotary pressure filter would offer distinct advantages to the plant operator
The slowly rotating single unit required much less power
wash-liquid and maintenance and the quantity and quality of the yield increased significantly
Laboratory tests were carried out that simulated the process on a small scale and the findings confirmed that the rotary pressure filter works more effectively than the centrifuges
The averaged cake washing results were improved by around 90%
The production of a solids-free filtrate meant there were no product losses as there had been with the centrifuges and a single filter was able to replace the three centrifuges
BHS-Sonthofen is supplying BASF with a plant for the mechanical reprocessing of lithium-ion batteries into black mass
This marks the third large-scale plant for BHS
with the first one having operated successfully for over a year
customers can benefit from the combined experience and know-how of this machinery and plant manufacturer from the South German Allgäu region
providing them with increased investment security..
“We are particularly proud that we have been able to secure another renowned and innovative customer like BASF.”
together with partners and customers celebrated the opening of Europe's first co-located center for battery material production and battery recycling
A significant component is the plant supplied by BHS for the mechanical processing of lithium-ion batteries
This plant is seen as an important step towards closing the loop for the European battery value chain and raw material supply
the plant will have a processing capacity of 15,000 metric tons of spent lithium-ion batteries and scrap from battery production per year
The BASF facility is currently under construction in Schwarzheide
where it already produces cathode active materials for lithium-ion batteries
The black mass produced at the plant contains valuable metals such as nickel
which undergo chemical extraction in a subsequent processing step at BASF
These metals are then utilized in the production of new battery materials
Recycling plant meets the high safety standards of the chemical industry
BHS-Sonthofen and BASF both equally benefit from this extensive cooperation
”The plant in Schwarzheide is being constructed to the highest environmental
To meet our customer’s stringent requirements
we have developed tailored solutions for our machines and components in close coordination with BASF,” Daniel Zeiler explains
reflecting on the results of the first year of cooperation
Knut Zöllner, Senior Vice President at BASF, confirms, “In BHS-Sonthofen, we have chosen a partner who seamlessly combines the worlds of classic recycling technology and chemical process technology particularly well
complementing BASF's own experience.”
In 2020, BHS-Sonthofen introduced its innovative and safe process for recycling lithium-ion batteries. The mechanical process consists of the main stages of crushing, drying and screening. Crushing takes place in two stages
enabling exceptional material disintegration and yielding the valuable black mass as the main product
while maintaining the highest quality standards
the continuous gas-tight process from shredder to dryer
ensures a safe evaporation of electrolytes
meeting BASF's stringent criteria for plant safety and environmental compatibility
The heart of the plant is the vacuum dryer of type HTC
BHS utilizes its in-house technologies and expertise: through its Process Technology business unit
the company is a leading global supplier of process technology components and systems for the chemical
BHS-Sonthofen has further optimized the technologies and process parameters used in the process
operation of the shredders is now easier and safer
enhanced accessibility allows for better cleaning and maintenance of the machines,” says Zeiler
BHS incorporated valuable operating experience gained from pilot and large-scale plants into the Schwarzheide project
“Battery recycling is a crucial prerequisite for fostering the circular economy and meeting EU quota requirements,” Zeiler concludes. "We are currently witnessing substantial investments in battery recycling on a global scale, and recycling technology is continuously improving
The process from BHS-Sonthofen has now more than proven itself in practice."
Recycling company in United Kingdom processes ASR fractions and electronic scrap using the BHS Rotorshredder..
British recycling specialists Recycling Lives commissioned a recycling plant that was planned and implemented by BHS-Sonthofen
The plant is designed to handle a variety of materials such as automotive shredder residue (ASR)
electric and electronic scrap (WEEE) as well as so-called “meatballs” (electric motors and motor armatures)
The process developed together with the company is based on a profitability analysis and ensures marketable end products
In the process of expanding capacities, the British recycling company Recycling Lives decided it required a plant that could process different materials simultaneously at its 15-acre Recycling Park in Preston
waste electrical and electronic equipment (WEEE)
After BHS had drawn up an initial concept for a plant
extensive tests were carried out at the Sonthofen test center with about two to three metric tons of each material required by the customer
BHS calculated profitability after tests in the test centre
Customers of BHS-Sonthofen need a validated basis for decision-making before they invest in a new plant. Data on throughput and material quality, among other parameters, is collected during the tests and analyses in the test center. This information is then used to create a mass balance a profitability analysis– a key advantage for customers. The recycling company used the calculation to estimate the profitability of the plant investment.”
the experts from BHS designed the plant based on the test data
The feed material is supplied to the Rotorshredder of type RS 3218 via a feeder
The tools of the Rotorshredder exert a very intense stress on the feed material through impact
The result is selective size shredding: Particle sizes are selectively reduced and composite materials are separated
All fine fractions of particle sizes smaller than 25 mm are processed on other existing plants
The fraction >25 mm is conveyed to a zigzag sifter
which frees the feed material from light material (fluff
The cleaned material is then transported via an overhead magnet to a cyclone separator
In the overall control concept BHS took these assemblies into account and also supplied the steel structures for these parts of the plant
which was developed by BHS together with the British customer
Recycling Lives’ Chief Engineer Gary Halpin explained: “Since the machine was installed three years ago downstream from our main shredder at the Recycling Park in Preston
it has proved efficient in further reducing the particulate size for more efficient extraction of metals and other materials from the waste stream
It is a valuable element within our waste processing operation
helping to extract maximum value and also increase the amount of material that can be recycled as we progress towards a circular economy solution.”

Intelligent pre-shredding with the RAPAX..
BHS-Sonthofen’s new RAPAX combines design and functionality in one powerful pre-shredder
this machine is perfectly suited for processing various metal fractions
smart control system also ensures efficient pre-shredding in every running direction
BHS has been developing and building shredders for over one hundred years
RAPAX was developed in close collaboration with an industrial designer
The aim was to outfit this innovative technology
which represents a new level in pre-shredding
The focus was on functional design elements that make the RAPAX sturdier and easier to maintain
such as the intersecting struts on the funnel
wall thickness and shape of the funnel are also sturdy and feature precise edges to avoid signs of wear and material build-up
The two planetary gears with belt drive are positioned side by side
Efficient shredding is the first important step to a functioning material cycle
BHS offers the RAPAX pre-shredder in a number of different designs and sizes to ensure that it can optimally process a wide range of input materials
It is available as part of either the 15xx or 20xx series in three different sizes
with shaft lengths ranging between 1.2 and 3.2 meters
These allow the RAPAX to effectively shred extremely bulky input material such as construction waste or white goods
Two different tool geometries are available
depending on the design – either the highly serrated BAT shape version for a higher throughput in the case of light waste
or the sturdy JANUS shape for heavy input material
The tearing table is located below the two shafts
which can be used along with the number of tools to determine the particle size
The electrical drive is also available in different power outputs – up to 400 KW can be installed on request
A hydraulic pusher device is optionally available
It ensures continuous material infeed when processing low-density
the center distance of the two shafts on the RAPAX has been deliberately selected to ensure that the tools do not interlock
This ensures an optimal infeed torque with minimal energy consumption at the same time
Fewer machine downtimes and easy maintenance
“The pre-shredding process sometimes involves a tremendous amount of force. So with that in mind, we placed a great deal of importance on the RAPAX being sturdy and easy to maintain,” says Ingo Schneemann, the responsible mechanical designer in crushing technology at BHS
Rubber buffers have been installed on the drive unit for this purpose
which absorb the impact and protect the gearbox from damage
The design of the tool and the reversing control system prevent material from wrapping around the shafts or adhering to them
The machine is also designed to ensure that wear parts such as the shafts and tearing table can be easily removed and replaced
BHS-Sonthofen offers a wide range of services to customers on-site
from installation and commissioning to technical service and maintenance agreements
An intelligent control system for maximum performance
The shafts can be controlled with total flexibility
The RAPAX is designed to shred material in every running direction
The control system makes it possible to select the appropriate program consisting of different movement sequences for every input material
“The input materials used by our customers can vary greatly
Whether it’s small electrical equipment or white goods
for example – our various programs ensure optimal shredding,” says Schneemann
The control system could do even more in the future
Plans for the future include using artificial intelligence to make it able to react even more flexibly to the input material
BHS is still collecting the appropriate data for this
but every RAPAX is already equipped to utilize it in principle

“To satisfy the growing demand in our products
the company has decided to establish a new production plant here in Slovakia,” the company said
which has recently expanded to China and Australia
BHS-Sonthofen is expected to invest €10 million and employ 100 people
BHS-Sonthofen wants to produce steel components for mixing plants
used in various industries in Prešov
“I have not even seen the project or talked to someone about the investment,” said Haniska Mayor Ladislav Šimkovič
Mixers required to facilitate construction of world’s largest roller-compacted concrete dam
THE Chinese-Pakistani consortium CEC-POWERCHINA and the Pakistan Frontier Works Office is building the Diamer-Basha Dam near the Chinese border in northern Pakistan – a construction project that will require 18.6 million cubic meters of mainly roller-compacted concrete (RCC) over the next few years
was awarded a contract to deliver six BHS twin-shaft batch mixers to Pakistan to meet this huge demand for concrete
two of which have already been built and delivered
The construction project is of key importance to Pakistan in terms of energy policy and represents closer co-operation between Pakistan and China
The dam is being built on the Indus river in northern Pakistan and will form a reservoir approximately 40km downstream from Chilas
The world’s largest roller-compacted concrete dam will be 272m high and is expected to use 17.1 million cubic meters of RCC and 1.5 million cubic meters of ordinary concrete
The supply and delivery of six BHS twin-shaft batch mixers for this major project includes four type DKX 7.00 mixers capable of producing seven cubic metres of hardened concrete per batch
and two type DKX 6.00 mixers each capable of producing six cubic metres of hardened concrete per batch
general manager of BHS-Sonthofen’s Tianjin site
is responsible for the construction and delivery of the mixers
He said: ‘The hydraulically bound base layers required for the dam
‘Our mixers are designed to handle demanding mixing tasks
With low wear on the mixing tools and the mixing trough lining
the twin-shaft batch mixers meet the highest demands for mix homogeneity and reproducibility
even with large quantities – ensuring optimum concrete quality.’
Two of the mixers built in Tianjin have already been delivered to the vast construction site
whilst the remaining four are due to follow by the end of the year
Co-operation with BHS-Sonthofen went so smoothly that even before delivery of the first two units
the customer had already suggested the prospect of a follow-up order
‘BHS are expected to deliver another six mixers next year,’ said Mr Laux
‘Having a location in Tianjin allows us to combine our expertise with regional proximity to the customer – this creates trust
or spare parts can be delivered quickly and easily.’
BHS supplied the modular filter plant as part of the crude gas cleaning stage for natural gas production in the South Ýolöten gas field
one of the world's largest natural gas fields in the South East of Turkmenistan
The filter plant is used for cleaning and refining the crude gas in the ‘amine sweetening’ process step
Featuring a filter area of about 80 m2 each
the candle filters remove impurities such as piping debris from the lean amine
This protects the actual core of the plant – the activated carbon filters – from foreign matter
The candle filters regenerate approximately 150 m3 of lean amine solution per filter unit every hour
The scope of supply also included the pre-coat station
all pumps and fittings as well as the entire measuring and control technology
The plant is integrated into the customer's process control system
the sour gas contains impurities such as carbon dioxide (CO2) and hydrogen sulphide (H2S)
which are absorbed in an amine scrubber and adsorbed by an activated carbon filter
The amine suspension is clarified by the BHS filter systems
They filter solid particles – piping abrasion and dust
for example – and thus considerably lengthen the life of the amine solution
The plant was shipped to Turkmenistan in 2011 in fifteen 40-foot containers
BHS adds that the modular construction principle enabled the plant to be erected in a minimum of time
BHS candle filters are batch-operated filters with vertically arranged
particularly for suspensions with a low solids content or with very fine
amorphous particles that are hard to separate
The candle filters can be used in a wide range of applications on account of their diverse modification potential
This is primarily in batch operation with dry discharge but also as slurry or wet-discharge filters in quasi-continuous operation
The filter candles essentially consist of the perforated support grid with evenly spaced welded rods
a textile filter cloth selected to meet the individual requirements
BHS claims that the unique design and the large
open cross-sections of the support grid and discharge pipes ensure good adhesion of the particles during filtration
a high filtrate flow rate and reliable cake discharge by gas blowback or backflushing from the filtrate side
The candles are mounted on individual collection registers
This allows selected registers to be isolated from the filtration process without interrupting operation
It is also possible for the residue to be removed from specific registers or discharged in portions
the project demonstrates that the company has successfully accomplished the evolution from a manufacturer of individual filter components to a supplier of complete plants
sales director for the filtration technology division at BHS-Sonthofen
the order represents a milestone in the company's history: “Whereas we previously used to supply mostly individual filter plants
we now additionally offer our customers the entire spectrum of plant construction from design through to commissioning – including the piping and steel structure
as well as the complete process control engineering
We are thus opening up new market segments as we are now addressing a broader range of customers.”
BHS-Sonthofen develops and manufactures machines and plants for mixing
recycling and filtration applications in the field of mechanical process engineering
The company focuses on customised solutions tailored to the specific requirements of individual industries
BHS has manufactured a wide range of filtration plants for solid-liquid separation in batch and continuous processes
A common feature of all BHS filters is that they work with a comparatively thin cake
The company supplies customers in the construction and building materials
pharmaceuticals and food processing industries as well as the environmental and waste management sectors
BHS-Sonthofen GmbH has been an independent group of companies since 1996
Its history stretches back to an iron-smelting works founded 400 years ago on the site of the present-day company premises
BHS-Sonthofen is a mid-sized global player with over 300 employees
The group of companies is headquartered in Sonthofen
At its biogas plant near Chandigarh in the state of Punjab
the Indian company Source Facility uses a BHS Biogrinder to process paddy straw
coconut shells and other organic waste materials
The Biogrinder works for multiple feed materials and allows for an efficient biogas production process..
India generates a large amount of agricultural waste
As burning organic waste is considered to be a major cause of air pollution
the government of India has been offering incentives to mitigate the pollution problem and convert paddy straw into biogas
biomass such as rice straw that is widely available in India is a promising source of renewable energy
“Especially in northern part of India
rice straw will be an important raw material for biogas production”
purchased a Biogrinder to process rice straw
empty coconut shells and fruit/vegetable waste
they tested shredding solutions from local providers
as these machines were not capable of handling multiple materials
“It was very important to Source Facility to have the freedom to allow a broad spectrum of feed materials”
the machine offers both excellent size reduction and defibration
which is critical for the biogas production process
The biogas is produced by micro-organisms during fermentation. The more defibrated the material, the more surface the bacteria have to colonize. Inside the machine is a rapidly turning, star-shaped rotor with a vertical shaft and massive crushing tools
the machine prepares it optimally for the next process step
Source Facility tested various materials for 2 weeks on trial
The Biogrinder was put into operation in late 2019 and the customer is very satisfied with the increase in Biogas production
“We are getting a lot of inquiries in India about biomass processing
as the government pushes toward more sustainable use of organic waste”
but many companies are planning to set up new plants across India
BHS-Sonthofen is offering an easy-to-maintain
particularly durable machine for efficient substrate processing.”
More efficient crushed sand production with new RPMF rotor impact mill from BHS-Sonthofen
BHS-Sonthofen have introduced their new RPMF rotor impact mill – a variant of their proven RPM rotor impact mill
The new RPMF machines are said to produce even finer fractions
making them more efficient at producing crushed sand
BHS designed both types of machines to be used primarily with pre-crushed
as impact crushing has proven to be the best method for crushing these kinds of materials
the new machine has been specifically developed to produce even finer output sizes
narrower milling gap and increased circumferential speed (of up to 90m/s) in the rotor
the RPMF machine archives a higher reduction ratio and delivers material containing a greater proportion of fine sand
the tests demonstrated that RPMF machines produce a significantly higher proportion of usable fine sand in the 0–1mm size range than RPM rotor impact mills
RPMF machines produce more than 50% more usable dry mortar sand,’ he said
The new RPMF machines also feature a significantly narrower gap between the grinding tools and the anvil ring
the new machines make sand production more efficient by reducing the return flow of coarse material and the number of times that material needs to pass through the mills
also means that these machines require less screening and conveyor technology
which is delivered into the machine from above via a central pipe
while the RPM rotor impact mill can be used to pre-crush feed fractions up to 56 mm
The milled material leaves the rotor through the gap between the rotor and the anvil ring
falling down through the two outlet chutes
the mill can alternate between clockwise and counter-clockwise operation
while easy-to-replace spacers allow the operator to modify the milling gap in accordance with the wear on the impact hammers
BHS-Sonthofen produce the new RPMF rotor impact mill in two different designs: the RPMF1116
which has a circumferential speed of up to 90m/s and a throughput of up to 25 tonnes/h; and the RPMF1516
which has a circumferential speed of up to 90m/s and a throughput of up to 55 tonnes/h
