Comminution processes: Basics and application to energy efficiency

What is the efficiency of a milling process? Different possibilities to define energy efficiency: 1. Specific energy of mill compared to new created surface energy → not meaningful, efficiency much smaller that 1% 2. Specific energy of mill compared to minimum

Ball mill liner | Magotteaux

Uses of a ball mill liner The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
