The main part of the
vetical roller mill is a rotary cylinder mounted on two large bearings and horizontally placed. The barrel is divided into several compartments by a partition board, and a certain shape and size of the abrasive body is installed in each warehouse. The vertical mill is generally made of steel balls, steel forgings, steel bars, pebbles, gravel and porcelain balls. In order to prevent the cylinder from being worn, the lining wall is installed inside the cylinder body.When the vetical roller mill turns, the grinding body is attached to the lining surface of the inner wall of the cylinder, which is attached to the lining surface of the inner wall of the cylinder, and is taken to a certain height (as shown in Figure 1) under the action of the friction force produced by the centrifugal force and the lining surface of the inner wall of the cylinder.
