Rotor Beater Mill SR 300
The SR 300 is the leader among the Rotor Beater Mills. Its high speed in comparison to the SR 200 allows a significantly higher throughput. The ground sample also has a larger fraction of fine material. Grinding chamber, feed hopper and material inlet and outlet are completely made from highquality stainless steel.
Application Examples
bricks, cement clinker, chemical products, coal, coke, drugs, feed pellets, fertilizers, food, pharmaceutical materials, plant materials, plastics, salts, seeds, soils, spices, sugar, ...
Product Advantages
- high throughput
- high final fineness
- versatile in use
- easy cleaning
- exchangeable grinding and sieve inserts
- quick-action door lock and motor brake
- safe design to CE standard
- 2-year warranty

Function Principle
Size reduction and deagglomeration in the SR 300 are achieved by hammering, impact and shear effects. The feed material passes from the hopper into the center of the grinding chamber where it is crushed between the rotor, sieve and grinding inserts. As soon as the material is smaller than the aperture size of the sieve it enters the collecting receptacle. The quick-acting door lock ensures easy access to the grinding chamber for quick cleaning. With their motor brake (braking time < 0.5 s), safety switch, splashback and access barrier in the inlet and outlet areas, Rotor Beater Mills offer the highest degree of operating safety.
