The trommel is used for the classification of large and small stones, as well as the separation of soil and stone powder in the stone plant; used for the separation of sand and stone in the sand and quarry; in the coal industry, used for the separation of lump coal and pulverized coal and coal washing (a part of coal washing machinery) ; In the chemical industry, the beneficiation industry is used to classify large and small lumps and separate powdery materials. It can be seen that its scope of application is wide.

The trommel can be equipped with a comb-type cleaning mechanism. During the screening process, the comb-type cleaning mechanism and the screening cylinder can move relative to each other to achieve the effect of uninterrupted cleaning of the screen body, so that the screening cylinder is in the entire working process. Always keep it clean, non-sticky, non-blocking, and does not affect the screening effect. According to different classification requirements, the grading stages of the drum screen are generally 1-4 sections from fine to coarse, and the materials from fine to coarse are screened out from one screen to the next screen, and materials larger than the screen hole of the latter screen are discharged The material port is discharged. The main structure of the trommel is a screening cylinder, which is composed of a number of circular screens, the whole is inclined to the ground level, and the outside is sealed by a sealed isolation cover to prevent environmental pollution.
