Their main function is to use effective friction force and centrifugal force to grind materials. Specifically, the barrel of the calcium carbonate mill is mainly made of rolled and welded steel plates. 

The flange on the barrel is connected with the inlet and outlet hollow shafts at both ends to form a whole with hinged hole bolts, and then the grinding body is installed in the barrel. 

The two ends of the cylinder are the feeding port and the discharging port. The devices inside the two hollow shafts provide channels for feeding and discharging, and the bushing inside can be replaced. 

The calcium carbonate mill cylinder moves around the horizontal axis, which generates a high centrifugal force in a certain process, makes it reach the specified height through the action of the mixture, and then falls in a parabolic arc. 

In this process, the material is affected by the medium and has a certain collision, and is also affected by the cylinder, crushed, rolled and ground.
