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 40 microns according to product.

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
