The ball mill consists of a rotating drum and a hollow cylinder filled with grinding media, typically small metal balls. Working Principle of a Ball Mill. The working principle of a ball mill is based on the rotation of the drum, which causes the grinding media to fall onto the material to be ground.
Different types of liners in cement mills are designed to optimize the grinding process and improve mill performance. For example, shell liners are designed to reduce the impact of the grinding media on the shell, while lifter liners are designed to lift the material and grinding media to enhance the grinding process.
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.
