ABSTRACT OF THE DISCLOSURE An agitator ball mill comprises a grinding container having a cylindrical grinding chamber which is defined by a grinding-chamber wall. At least one agitator, which is provided with projecting agitating tools is arranged in said grinding chamber. The agitator and the grinding container can be rotatably driven about their …

The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.

For a coal mill, we usually recommend a light classifying liners and for raw mills we recommend heavy classifying liners. If the raw materials are particularly coarse, a mixed solution might be best. This could be either by replacing the first few rings – e.g., the first 1.5 m of the chamber – with step lining or combining wave lining

The ball mill was short with a large diameter (L/D = 0.5) and very large size grinding media. The mill was fitted with peripheral screens that passed coarsely ground material to the tube mill, which was long with a smaller diameter (L/D= 5.0). Such a system was necessary then, as the feed to the ball mill was fairly large in size.

Carbide-Tipped Double-Chamfer End Mills. These carbide-tipped end mills provide a sharper, harder cutting edge and better wear resistance than high-speed steel without the brittleness of solid carbide. Their teeth are angled on both sides so you can make top and bottom chamfer cuts without having to flip the workpiece.
