Cross Beater Mill SK 100
The Cross Beater Mill SK 100 comfort is suitable for coarse and fine size reduction, either in batches or continuously. It can process medium-hard and brittle materials with a hardness of up to approx. 6 on Mohs’ scale. The SK 100 is intended for universal use: from sample preparation in laboratories and industrial plant, through pilot installations up to preparing sample batches in production facilities.
Application Examples
cement clinker, coal, coke, glass, gravel, minerals, ores, oxide ceramics, slag, soils, ...

Function Principle
Size reduction in the SK 100 takes place by hammering, impact and shearing 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.
