One primary classification of end mills is their type of cutting edge, which can be either center-cutting or non-center-cutting. Center-cutting end mills can make plunging cuts, allowing them to create slots and pockets in materials, whereas non-center-cutting end mills are typically used for peripheral cutting.

Ball mills produce 1 to 50 ton/h power of which about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batch-operated mill, a measured …
A ball mill is a cylindrical device that rotates around its axis, partially filled with the material to be ground plus the grinding medium (usually ceramic balls, flint pebbles, or stainless steel balls). As the mill rotates, the grinding media crushes and grinds the material against the inner surface of the mill chamber, creating a fine powder
Pebble ball mill: Pebble mills are sometimes called jar mill or pot mill which works on the principle of attrition and impact. The grinding is effected by placing the substance in the cylindrical vessel or jar vessels that are lined by porcelain or other hard substance containing pebbles or balls. The cylindrical vessel revolves horizontally on ...

The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
