ROTOR IMPACT MILL 4 BHS Rotor Impact Mill Superior Machine Technology Production of Quality Sand The BHS Rotor Impact Mill is a high-performance crusher with a vertical shaft. The rotor impact mill enables you to achieve a high reduction ratio and excellent particle shape. The mill is suitable for crushing all low to moderately abrasive minerals and is therefore used predominantly in the production of sand for the concrete, asphalt and dry mortar industries. Operational unit Unique crushing principle The machine and drive train are assembled onto a base frame as a unit that is ready for...

ROTOR IMPACT MILL (RPM & RPMF) 6 Two Versions of the Rotor Impact Mill The RPM is the rotor impact mill used in the building materials industry. The machine has been a proven reliable tool in the production of sand for many years. The RPMF pulverizer produces even finer fractions, and the output material contains a significantly higher percentage of fine sand. BHS rotor impact mills are not only used in the production of sand for the dry mortar industry. They have also proved themselves useful in the production of surfaces for sports facilities, as well as in the milling of fertilizers from...

Functional Description Rotor Impact Mill RPM Rotor Impact Mill RPMF – the pulverizer Replaceable crushing tools The input material is fed into the machine from above at the center. When it impacts the rotor, the material is accelerated towards the outside through centrifugal forces; there, the horses­ oe-shaped hammers hit it and throw it against the h anvil ring. Here, in the milling gap, it is crushed as a result of the impact and shearing forces. The material leaves the rotor through the gap and falls down through two outlet chutes. The pulverizer uses the same crushing principle as the...

Reinforced cover lining In order to increase the service life, a cover with reinforced lining can be selected as an option. Electro-hydraulic cover opening For even faster opening of the machine cover for maintenance and inspection, an optional electro-hydraulic actuation mechanism is available. Electrical terminal box If required, all electrical wiring can be bundled in a terminal box for easy installation. Intensive cooling In the event of high ambient temperatures or if the material to be processed is hot, a supplementary lubrication unit featuring a larger storage volume and stronger...

CUSTOMER TRIALS TECHNISCHE DATEN 15 Testing gives certainty We operate a large-scale test plant on our Sonthofen business premises. It comprises all of our crushing machines in production scale. We offer to perform crushing tests on your input material at this facility. Various machine parameters can be tested intensively. This is followed by a detailed evaluation of the data and a grain-size analysis, which serves as the basis for optimal machine configuration. Performance data 1) The throughput rate depends on the circumferential speed of the rotor and the grading curve of the input...
