Ball mills grind various ores and other materials either wet or dry. There are two kinds of ball mills, grate type and overflow type, due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, including Hardened steel, stainless steel, ceramic, flint pebbles.
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.

Working Principle of a Ball Mill. The working principle of a ball mill is based on the rotation of the drum, which causes the grinding media to fall onto the material to be ground. The force of impact breaks the material into smaller particles, while the friction between the balls and the material causes further grinding and refinement. The ...
Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill …
the little ball mill is made from lego and a shavecream box. But the finest dust does stick on the walls from the shavecreambox!!! not good .
