What is a Ball Mill? | Economy Ball Mill
What is a 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.

The actual ball mill was a section of a 30 cm diameter mill: The length of this section was only 1 cm long, fitted with six equally spaced lifter bars of square cross-sec- tion. The discs were 3.4 cm in diameter and 0.8 cm thick. The discs were positioned in the mill, and a plexiglas end-plate was bolted to the lifter bars. ...
Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
