Circular vibrating screen is a new type of screening equipment with multi-layers and high efficiency. It is named because of the circular movement of the material on the screen surface. Circular motion vibrating screens are widely used in product classification in mining, metallurgy, building materials, transportation, energy, chemical, coal, electric power and chemical industries. It is ideal equipment for the crushing and screening process.
Circular vibrating screening machine is mainly composed of a screen box, screen mesh, vibrator, vibration-damping spring device, and underframe. The screen mesh is the main vulnerable part. According to the requirements of material products and users, high manganese steel woven screen, punching sieve plate and rubber sieve plate can be used. There are two kinds of sieve plates: single-layer and double-layer, and all kinds of sieve plates can meet the different requirements of screening effect. The angle of screen surface can be adjusted by changing the height of spring support.
The design principle of stone circular vibrating screen is the following process: it uses cylindrical eccentric shaft exciter and eccentric block to adjust the amplitude. The vibrator is installed on the side plate of the screen box, and the motor drives the exciter and eccentric block to produce high-speed rotation and centrifugal inertia force through the triangle belt, so as to stimulate the screen box to produce a circular motion with a certain amplitude. The material on the inclined screen surface receives the impulse from the screen box and produces continuous throwing motion. When the material meets the sieve surface, the particles smaller than the sieve hole are passed through the sieve to achieve classification.
The mining circular vibrating screen has many significant advantages in structure and performance:
1. Ring groove rivet connection, advanced structure, strong and durable. Tire coupling, flexible connection, stable operation.
2. Adjustable amplitude, multi-layer screening, high screening efficiency, suitable for mining, sandstone, and other industries.
3. The screen crossbeam and screen box of sand circular vibrating screen adopt high strength bolts, with simple structure and convenient maintenance.
4. Efficient circular vibrating screen adopts small amplitude and large inclination angle structure, with high screening efficiency and large processing capacity.
5. The vibrator adopts large clearance bearings, with thin oil lubrication, so as to has low noise and long service life.
6. Dust pollution can be prevented when closed structure fuselage is adopted.
