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 metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
Factors Affecting the Grinding Efficiency of Ball Mills
1. Speed of rotation. The rotation speed is an important parameter that directly affects the grinding efficiency of the ball mill. When the rotation rate is too low, the impact on the material will be small, which will lead to substandard fineness, thus affecting the grinding efficiency; when the rotation rate is too high, the impact energy of ...
