For many mining industry factories or many grinding mill operators, they are familiar with LM vertical roller mill and ball mill machine. However, both LM vertical roller mill and ball mill have many difference, in this article, we will mainly talk about the difference between LM vertical roller mill and ball mill.

LM vertical roller mill working principle: after the material was fed into the space between the grinding roller and grinding ring in the process of synchronous rotation of the shovel and the grinding roller, and forms a cushion material layer. And then the material on this layer is grind between the grinding roller and the grinding ring. Thus, the purpose of powder production is achieved.

Ball mill working principle: the ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials.
