Opening the ball mill box reveals a user's manual, a mill base, two mill jars, and five extra drive belts. Unpacking the Ball Mill The ball mill jars The first thing that struck me when I first looked at these mills was the nice quality of the mill jars. These things are really heavy-duty, and have a very solid closing and sealing-lid assembly.

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Small versions of ball mills can be found in laboratories ...

The rotational speed of the milling jar should be ~65% of the critical speed of the jar. The critical speed is 'the speed when a ball mill becomes a centrifuge' and may be calculated for a specific jar and ball diameters as follows: CS[rpm] = 2676 / SQR( JarID[mm]-BallOD[mm] ). The material to be milled should be reduced to appr. 8 mesh prior ...
