Lump crusher

for crushing of agglomerates and lumps

Whenever agglomerates and lumps in the food and chemical industry need to be eliminated and milled, the lump crushers MKB can be used. By means of slicing and grating they mill dry, brittle to slightly moist starting products into the desired final grain size. Thanks to its modular construction the lump crushers can be easily integrated into existing production lines or used as stand-alone devices.

Lump crusher


The clumped and hardened bulk goods are fed into the lump crusher through the inlet using gravity. The rotor blades rotate, press the product through a grating sieve and mill the agglomerates to the desired final grain size.

Areas of use

  • Reduction of grain size
  • Milling after emptying of big bags and sacks
  • Milling prior to pneumatic transportation
  • Milling prior to mixing
  • Milling of filter cakes
  • Milling of broken goods and goods for reworking
