[0002] Circular vibrating screen, also known as circular vibrating screen, is a new type of vibrating screen with multiple layers and high efficiency. The working principle of circular vibrating screen is to use the motor to make the eccentric block of the vibrator rotate at high speed through the V-belt, thereby exciting the screen box to produce 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, which produces continuous throwing motion. In the process of the material meeting the screen surface, particles smaller than the screen hole are allowed to pass through the screen, thereby achieving classification. The main features of circular vibrating screen are: reliable structure: circular vibrating screen is usually made of welded steel plates, with high strength and good rigidity, and can withstand large vibration force and material impact; strong exciting force: the use of cylindrical eccentric shaft vibrator and eccentric block to adjust the amplitude can generate strong exciting force, so that the material can fully roll and bounce on the screen surface; high screening efficiency: due to the continuous throwing motion of the material on the screen surface, the material screening task can be completed efficiently, improving production efficiency.
