What is a Ball Mill? Economy Ball Mill
A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The The wear of balls used during a grinding process is considered one of the losses that cause an increase in the operating cost allocated to the ball mill [21].
