Product catalog summary
Company Overview
BHS-Sonthofen is a mid-sized, owner-operated group based in Sonthofen, Germany, with subsidiaries in the US, China, India, and Russia. The company specializes in mixing, crushing, recycling, and filtration technology, offering state-of-the-art solutions globally.

Experience and Expertise
With over 100 years in manufacturing crushers and mills, BHS-Sonthofen has specialized in impact crushing for the past 50 years, focusing on vertical-shaft impact crushers.

Rotor Impact Mill (RPM)
The BHS Rotor Impact Mill is a high-performance crusher with a vertical shaft, designed for producing high-quality sand with a cubical grain shape. It is suitable for low to moderately abrasive minerals, primarily used in concrete, asphalt, and dry mortar industries.

Unique Crushing Principle
The mill features a unique impeller rotor that creates a high reduction ratio and excellent particle shape. The high circumferential speed and small gap width between the hammers and anvil ring result in targeted crushing.

Machine Technology
The RPM is equipped with a recirculating oil lubrication system, ensuring low-maintenance and reliable operation. It features easy maintenance with exchangeable wearing parts and vibration absorption technology.

Layout and Function
Material is fed through a central tube, accelerated by the rotor, and crushed by impact and shearing forces. The process is repeated for intensive crushing, with results optimized by adjusting the gap size and rotor speed.

Applications
The RPM is used for producing sand for construction, asphalt, dry mortar, sports surfaces, and fireproof materials. It also grinds fertilizers from limestone, dolomite, and synthetic sources.

Options and Accessories
Available options include reinforced cover lining, electro-hydraulic cover opening, electrical terminal box, intensive cooling, air cannons, and a control system with PLC and frequency converter.

Customer Trials
BHS offers customer-specific testing at their technical center in Sonthofen, allowing for optimal machine configuration based on detailed evaluations and grain-size analysis.

Technical Data
The document provides detailed specifications for different RPM models, including rotor dimensions, number of hammers, circumferential speed, drive power, throughput rate, and input size.

Production of quality sand Superior machine technology Unique crushing principle Operational unit The impeller rotor of the BHS rotor impact mill is unique worldwide. The high circumferential speed of the rotor results in an almost permanent gap between the tips of the horseshoeshaped hammers and the anvil ring. The small gap width and the high energy input due to the circumferential speed result in a very high, targeted crushing ratio. The machine and drive train are mounted on a base frame as a unit that is ready for installation. A large cover that can be raised hydraulically and pivoted through...

Layout of the rotor impact mill Functional description The input material is fed into the machine from above through the central feed tube. When it hits the rotor, it is accelerated outward by the centrifugal forces, where it is then caught by the horseshoe-shaped hammers, which impel it against the anvil ring. Here the rock is crushed as a result of the impact and shearing forces. Repelled by the anvil ring, the material hits the hammers again, is further crushed by the impact, and is then thrown back against the anvil ring. This process is repeated several times, resulting in intensive multiple...

Design of the rotor 1   Exchangeability of the crushing tools: The anvil ring elements are attached to the mill housing. The horseshoeshaped impact hammers are seated on the rotor and are held on the rotor journal by centrifugal force. Both the anvil ring and the impact hammers can be easily exchanged manually. 2   Adjustability of the gap: A set of exchangeable spacers is provided for adjusting the annular gap. As the wear of the impact hammers increases, the gap width can be readjusted simply by exchanging spacers of different sizes (shown red in the graphic). 3   Optimization of the service...
