What is Laboratory Ball Mill? MRCLab

A laboratory jar (drum) ball mill is a type of grinder used to grind materials of large feed sizes and large sample amount into fine powder. The jar is filled with balls, usually made of steel or ceramic, that grind the material as the jar rotates. The principle of working is simple: the rotation of the jar causes the balls to collide with the ...
