Efficient grinding in the second grinding compartment
The classifying lining provides efficient finer grinding of the coarse ground material. In the second compartment the material is primarily ground using pressure and friction, whereby the classifying lining retains the grinding balls with the largest diameter at the beginning of the compartment and the successively smaller balls at the end of the grinding path.
- Efficient grinding: Balls with the largest diameter are retained at the beginning of the compartment, balls with the smallest diameter at the end of the grinding path
- A combination of classifying with two types of lifter plates is possible, with wave liners or progressive activator plates. Both kinds of lifter plates lead to a cascading motion of grinding balls, and an optimum material transport through the second compartment
