Retsch Rotor Beater Mill SR 200 in Mills

Retsch Rotor Beater Mill SR 200

The Rotor Beater Mill SR 200 is suitable for coarse and fine size reduction, either in batches or continuously. It can process dry, soft, medium-hard, organic and inorganic substances. The SR 200 is intended for universal use: from sample preparation in laboratories up to preparing sample batches in pilot plants or production facilities.

Application Examples
bentonite, chemical products, coal, coke, drugs, feed pellets, fertilizers, food, graphite, gypsum, herbs, pharmaceutical materials, plant materials, plastics, powder coating, resins, rice, salts, seeds, soils, spices, sugar, ...

Product Advantages

• suitable for batchwise operation of larger quantities
• high final fineness
• exchangeable grinding and sieve inserts
• optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
• optional distance rotor to reduce frictional heat
• quick-action door lock and motor brake
• defined final fineness due to bottom sieves with aperture sizes from 0.08 - 10 mm
• maximum peripheral rotor speed 24.5 m/s

Function Principle
Size reduction and deagglomeration in the SR 200 are achieved by 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, the SR 200 offers the highest degree of operating safety.


with rotor, 240 mm filter hose and collecting receptacle (please order retaining frame, sieves and optional base frame SR 200 separately)
