Classifying liners

Obtain the best grinding media classification from the inventor of the concept

Classifying liners ensure a quick and efficient media classification to adapt the grinding charge to the material's granulometry, an efficient attrition rate and a smooth material flow.

  • Reduced energy consumption (kWh/t) thanks to constant optimum grinding charge classification 

Magotteaux develops different types of classifying liners:

With its reduced weight (of up to 35% vs traditional 2nd chamber mill liners), Xclass® allows an easier handling and increased safety.

Classoline®, the reference in classifying lining systems.
