Size reduction - Solids and powder milling -

Impact Mills: Hammer mills Pin mills Universal mills : The size reduction is ensured here by impacting the product against a solid surface. The solid surface is actually made by different kind of beaters rotating at very high speed. A pin mill is equipped with a static disc mounted with several pins and a mobile one also mounted with pins. When the product is forced passing through the system

Best energy consumption - International

The ball mill has been the industry's workhorse for over a century and despite its estimated meagre four per cent efficiency, little has changed over the years other than increases in the wear resistance of mill internals and the scale of the equipment. The addition of closed circuiting and progressively higher efficiency separators has improved cement product quality and produced higher

Ball Mill - an overview | ScienceDirect Topics

The difference in speeds produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. Planetary ball mills are smaller than common ball mills, and are mainly used in laboratories for grinding sample material down to very small sizes
