- breaking or grinding up of a material in mining
Under the effect of centrifugal force, the material moves to the edge of the millstone. Material than be ground by the force of the roller and smashed under extrusion, grinding and cutting. At the same time, air is blew up around the millstone and bring up the ground material. The air will blow the coarse material back to the millstone.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The milling process industry is made up of all manufacturers that are involved in process technology that is used for breaking down, separating, sizing or classifying bulk materials. Milling processes can also be used to remove contamination or water/moisture from bulk materials to produce dry particles prior to transport.

Grinding, on the other hand, is a machining process that involves the use of a disc-shaped grinding wheel to remove material from a workpiece. There are several types of grinding wheels, some of which include grindstones, angle grinders, die grinders and specialized grinding machines. Regardless of the grinding wheel, though, all grinding ...

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

If the lining is transmitting the energy from the rotating mill to the charge, the grinding media is doing the actual grinding work. Breaking rock of a certain size and with certain properties requires a certain energy – and that determines the top media size. To get the final finer product, smaller sizes of media are required.

During each cycle, the material undergoes the breaking force from one side while it is moving downwards by gravity on the other. The material can move lower in the chamber until the next compression cycle. 3 to 6 grinding and gravity drop cycles happen in one pass through the chamber (multi-compression).
