Cross Beater Mill SK 300

Cross Beater Mill SK 300

Retsch | Materials Processing

The Cross Beater Mill SK 300 is suitable forcoarse and fine size reduction,
either in batches or continuously.It can processmedium-hard and brittle materialsand is easy to operate.

With itsadjustable speedof 2,000 to 4,000 rpm the SK 300 is intended for
universal use: from sample preparation in laboratories up to preparing sample batches in pilot plants or production facilities.

Product Advantages

  • suitable for batchwise operation of larger quantities
  • adjustable speed for different applications
  • defined final fineness due to bottom sieves with aperture sizes from 0.12 - 10 mm
  • easy cleaning thanks to exchangeable push-fit grinding insert, rotor and sieve
  • wide range of accessories including various collection and feeding systems, rotors and sieves
  • electric engine brake
  • central locking device
  • Optional cyclone available

Functional Principle

Size reduction in the SK 300 takes place byimpact 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.
