High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

The triple-roller mill is mainly used in paint, ink, pigment, plastic, etc., especially milling and dispersing products. It achieves required grinding effect by the friction and crushing among the three horizontal rollers rotating at different speeds. The clearance between the rollers is adjusted manually.

The vertical roller mill (VRM) is popular and widely used for grinding of coal and raw materials. The vertical mill is energy efficient with low specific wear rate. Vertical mill supports drying of the feed material, grinding, separating, and material transport inside the mill.

In a vertical roller mill, materials to be ground fall upon the center of a rotating grinding table.Centrifugal force causes the materials to spread out evenly towards the edge of the plate. As particles lying flatly on the plate reach a certain thickness, they are ground or crushed by multiple pairs of rollers.

Precision roll grinders usually attach a workpiece to a rotating axis, with a grinding wheel rotating on the outside diameter of the object, removing material to a specified tolerance. New or refinished rolls may undergo different finishing processes after precision roll grinding, including coating or superfinishing.

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
