Rotary screen, also called drum screen or rotating screen, is mostly used to screen materials with larger particles. It is constructed as a slightly inclined rotating drum with a screen on the surface. During screening, materials are added into the drum from the entrance, and fine materials pass through the sieve holes and come out, while coarse materials move along the inclined surface of the drum and are discharged at the outlet end. Trommel screens are available in cylindrical, conical, hexagonal and octagonal shapes, and can separate the crushed materials into two or more different particles according to particle size. Its structure is simple, reliable, easy to maintain and has a wide range of uses.

PRODUCT ADVANTAGES 

1.High screening efficiency.Because the equipment has a plate cleaning mechanism, it can never block the screen, thus improving the screening efficiency of the equipment.

2.Good working environment.The entire screening mechanism is designed in the sealed dust cover, completely eliminating the dust flying phenomenon in the screening and improving the working environment.

3.Low noise of the equipment.During operation, the noise generated by the material and the rotating screen is completely isolated by the sealed dust cover, which reduces equipment noise.

4.Convenient maintenance.The equipment seals the equipment observation window on both sides of the dust cover, and the staff can observe the operation of the equipment at any time during work.

5.Long service life.The equipment screen is composed of several annular flat steels, and its cross-sectional area is much larger than the screen cross-sectional area of other separation equipment screens.

WORKING PRINCIPLE

The self-clearing cage drum screening machine performs reasonable rotation of the equipment center separation cylinder through the gearbox type deceleration system. The center separation cylinder is a screen composed of several annular flat steel rings. The center separation cylinder is installed with the ground plane. In the inclined state, the material enters the cylinder net from the upper end of the central separation cylinder during the working process. During the rotation of the separation cylinder, the fine material is separated from the top to the bottom through the screen interval composed of the annular flat steel, and the coarse material is separated from the lower end of the separation cylinder. Drain into the pulverizer. The device is provided with a plate type automatic cleaning mechanism. During the separation process, the screen body is continuously "combed" by the cleaning mechanism through the relative movement of the cleaning mechanism and the sieve body, so that the sieve body is always cleaned throughout the working process. It will not affect the screening efficiency due to the clogging of the screen.
