Office building at BHS-Sonthofen

TRANSFORMING MATERIALS INTO VALUE The company BHS-Sonthofen is an owner-operated group of companies in the machinery and plant engineering sector, based in Sonthofen, Germany. We offer technical solutions for mechanical process engineering with its focus on mixing, crushing, recycling, and filtering. With more than 300 employees and several subsidiaries, BHS-Sonthofen has a global presence. Over 100 years of experience in crushing technology We built the first crushers a good 100 years ago for the rock and stone industry. In addition to targeted crushing, this market demands robust,...

ROTOR IMPACT MILL 4 BHS rotor impact mill The BHS rotor impact mill is a high-performance crusher with a vertical shaft for use in the recycling industry. The unique impeller rotor in conjunction with the toothed anvil ring provides intensive processing of the infeed good. Composite parts are selectively crushed and separated, entangled materials are separated out, and brittle-hard materials are crushed extremely intensively. Metals are also shaped into balls and cleaned.

Unique crushing principle Selective crushing The impeller rotor of the BHS rotor impact mill is the only one of its kind in the world. The circumferential speed of the rotor generates centrifugal forces. They bring about a high level of energy input into feed stock, which is then intensively processed by impact and shear forces with the help of the crushing tools. The rotation creates a practically permanent gap between the tips of the horseshoe-shaped hammers and the anvil ring. Once the material is small enough to fit through this gap, it leaves the working chamber. Brittle materials,...

RPMV & RPMX ROTOR IMPACT MILL 6 Rotor impact mill available in two models The RPMV is a rotor impact mill for the recycling industry. The ball shaper, which has proven itself for many years in the widest variety of applications in the recycling industry, sets a new milestone with the RPMX. The RPMX rotor impact mill is a turbo-ball shaper. Used for the reclamation of valuable materials from fine fractions containing metal, such as stainless steel and cable strands. These had previously been considered problematic. RPMV rotor impact mill – the ball shaper The RPMV has proven itself in...

RPMX rotor impact mill – the turbo-ball shaper A higher circumferential speed and the considerably smaller grinding gap are characteristic for the RPMX. It is therefore the ideal machine for the ball shaping and separation of composite parts with grain sizes from 0 to 15 mm. RPMX rotor impact mill with rotor cover plat

Functional description RPMV rotor impact mill – the ball shaper RPMX rotor impact mill – the turbo-ball shaper The infeed material is supplied to the center of the work chamber from above. When it hits the rotor, it is accelerated outwards by centrifugal forces, struck by the horseshoe-shaped impact hammers and propelled against the anvil ring. Intense impact and shear crushing takes place in the grinding gap during the process. The material subsequently leaves the working chamber and falls downwards through the two discharge chutes. The material is selectively transported into the gap...

ROTOR AND SPACERS 9 www.bhs-sonthofen.com Advantages of the rotor Exchangeability of the crushing tools The anvil ring elements are suspended on the mill housing (RPMV) or bolted on (RPMX). The horseshoe-shaped impact hammers lie on the rotor and are held against the rotor journal by centrifugal force. Both the anvil ring and the impact hammers can be replaced easily. Adjustment of gap A set of interchangeable spacers enable the annular gap to be adjusted. As wear on the impact hammers progresses, the gap width can be adjusted by means of the exchange of spacers. (Available in different...

Electro-hydraulic lid opening An optional electro-hydraulic actuation is available for fast opening of the machine lid for maintenance and inspection purposes. Electrical installation in terminal box If required, all electrical lines can be brought together in a terminal box in an assembly-friendly manner. Intensive cooling If there are high ambient temperatures or if the temperature of the infeed material is relatively high, a lubrication oil system with a larger storage volume and an increased cooling performance can be supplied. Air cannon To reduce the caking in the discharge area, the...

Tests produce certainty At our company premises in Sonthofen, we operate a test facility on a large technical scale. All of our crushing machines are installed there. The crushed material can be separated into fractions using a screen or overbelt magnet. We can carry out treatment trials with your infeed material using this plant. Various machine parameters can be tested. A box feeder is available for larger quantities of feed stock. All test results are gathered, documented, and analyzed in accordance with jointly agreed criteria. BHS technical center in Sonthofen for customer-specific...
