Cross Beater Mill SK 100
The Cross Beater Mill SK 100 is suitable for coarse and fine size reduction, either in batches or continuously. It can process medium-hard and brittle materials and is easy to operate.
The SK 100 is intended for universal use: from sample preparation in laboratories up to preparing sample batches in pilot plants or production facilities.
Application Examples
cement clinker, chamotte, coal, coke, glass, granite, gravel, gypsum, minerals, ores, oxide ceramics, slag, soils, ...
Product Advantages
- suitable for batchwise operation of larger quantities
- defined final fineness due to bottom sieves with aperture sizes from 0.12 - 10 mm
- exchangeable grinding and sieve inserts
- wide range of accessories including various collection and feeding systems, rotors and sieves
- easy cleaning
- motor brake
- central locking device

Function Principle
Size reduction in the SK 100 takes place by impact effects. The feed material passes from the hopper directly into the center of the grinding chamber, where it is caught by the cross beater and ground between the baffle plates of the cross beater and the toothed grinding insert.
As soon as the material is smaller than the aperture size of the bottom sieve used, it passes through the sieve and enters the collecting receptacle. The air drawn in through the hopper by the cross beater accelerates the discharge of the ground material. The airborne fine fraction is separated off by a downstream filter system.
