ROTOR IMPACT MILL 4 BHS Rotor Impact Mill The BHS rotor impact mill is a high-performance, verticalshaft crusher designed for the recycling industry. The unique impeller rotor, combined with the toothed anvil ring, results in intensive stressing of the input material. Composite materials are selectively crushed and separated, entangled materials are singled out and brittle-hard materials undergo intense size reduction. At the same time, metals are shaped into balls and cleaned.

Unique crushing principle Selective crushing effect The impeller rotor of the BHS rotor impact mill is unique worldwide. The circumferential speed of the rotor generates centrifugal forces. These result in high energy input into the feed material, that is then intensively processed by means of impact and shear forces imparted by the crushing tools. The rotation results in a near-permanent gap between the tips of the horseshoe-shaped hammers and the anvil ring. As soon as the material is small enough to fit through this gap, it leaves the working chamber. Composite materials in the input...

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...

Design of the rotor Exchangeability of the crushing tools The anvil ring elements are attached to the mill housing. The horseshoe-shaped 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 without tools. 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). Optimization of the service life...

OPTIONS AND ACCESSORIES 9 www.bhs-sonthofen.com Electro-hydraulic cover opening Control system For fast opening of the machine cover for maintenance and inspection, an optional electro-hydraulic actuation mechanism is available. All the cabling can be connected to a terminal box for easier installation. As an alternative to integration in the system controller, the machine can be supplied with a PLC (including touch panel) and, if required, with a frequency converter to ensure selfsufficient operation and monitoring of the machine functions. Additional plant components can be integrated...

Tests give certainty We operate an all-weather, industrial-sized treatment plant on our premises in Sonthofen. All our crushing machines are installed in this facility. The crushed material can be separated into different categories using a sieve or overbelt magnet. We can perform crushing tests using your input material with this plant. A variety of machine parameters can be tested. A box feeder is available for large material quantities. All test results are recorded, documented and analyzed according to mutually agreed criteria. BHS technical center in Sonthofen for customer-specific...
