The circular vibrating screen
is a new type of multi-layer, high-efficiency vibrating screen with circular motion. The circular vibrating screen adopts a cylindrical eccentric shaft exciter and an offset block to adjust the amplitude, the material sieving line is long, and the screening specifications are many. It is suitable for screening sand and gravel materials in quarries, and can also be used for product classification in coal preparation, mineral processing, building materials, electric power and chemical industries.
The circular vibrating screen has the characteristics of reliable structure, strong excitation force, high screening efficiency, low vibration noise, sturdiness and durability, convenient maintenance, and safe use. The main structure of the circular vibrating screen is composed of an eccentric vibration exciter, a screen box, It is composed of motor, base and supporting device.
The working principle of the circular vibrating screen: the motor makes the eccentric block of the exciter rotate at a high speed through the triangular belt. The running eccentric block produces a large centrifugal force, which stimulates the screen box to produce a circular motion with a certain amplitude. The material on the screen is subjected to the impulse transmitted by the screen box on the inclined screen surface to produce continuous throwing motion, and the material meets the screen surface. In this way, the particles smaller than the mesh are passed through the sieve to achieve classification.
Use and maintenance of the circular vibrating screen: the vibrating screen should be started when there is no material on the screen surface, try to avoid starting with the material, and feed the material after the screen machine runs smoothly. The feeding should be s*ped before the machine is s*ped, and the machine should be s*ped after the surface material is removed. During the working process, the operation of the sieve machine should be observed frequently. If abnormal movement or abnormal noise is found, the machine should be shut down and checked in time to find out the cause and eliminate the fault.
