Colloidal Mill

Inline and offline colloid mill - MCB

The Colloid Mill - MCB is a mill with stainless steel, perforated plates or corundum grinding elements used for fine grinding and homogenization of liquids, pasty and viscous products, capable to reduce the particle size down to 1 micron.

Working principle

Based on a rotor rotating at high speed and very close to a conical stator. The particle size is regulated by modifying the gap between the rotor and the stator.


  • Flow rates from  0,5 up to 10 m³/h
  • Drive up to 75 KW
  • Off line model with feed hopper for solids
  • Inline model in recirculation mode
  • Tightness by simple mechanical seal
  • Particle size regulation by a mechanical device
  • High shear effect to obtain fine particle sizes
  • Exchange of grinding rotors  
  • ‘CE’ marking according to the Safety for Machinery Directive 2006/42/CE
