Product Overview: SH rotary screen is a new type of screening equipment developed by our company after years of practice by absorbing the advantages of similar products at home and abroad. The utility model has the advantages of simple structure, easy maintenance, stable and reliable work, low vibration and low noise. It can be widely used for screening and grading raw coal, sand, gravel and other materials in electric power, mining, metallurgy, building materials, chemical and other industries. Equipment structure and working principle: This machine is mainly composed of motor, reducer, drum device, frame, sealing cover, inlet and outlet. The roller unit is mounted on the rack at an angle. The motor is connected to the drum device through a reducer through a coupling, and drives the drum device to rotate around its axis. When the material enters the drum device, it is due to the inclination and rotation of the drum device. The material on the screen surface is turned over and rolled, so that the qualified material (the product under the screen) is discharged through the screen of the outer circle of the drum, and the unqualified material (the product on the screen) is discharged through the end of the drum. As the material flips and rolls in the drum, the material stuck in the screen hole can be ejected to prevent the sieve hole from being blocked. Technical features: 1. The roller device is sealed by the sealing cover of the body, so as to ensure that the equipment can effectively prevent dust overflow and reduce dust pollution during the working process. When replacing the screen, you only need to open the body sealing cover to replace it, which is convenient to operate. 2. The screen is made of 60S12mn spring steel wire or 16MnR flat steel, and the screen hole is uniform. The screen has high hardness, little wear and long service life. 3. The machine is equipped with a cleaning device, which can effectively remove debris blocking the screen hole and keep the screen surface clean. 4. The transmission device of this machine has two forms: cycloid reducer, roller straightener and ZQ series reducer. The installation position is specified separately when ordering at the feed end and the discharge end.
