Vibrating Screen

Granite, marble, basalt, limestone, quartz, pebble, copper ore, iron ore and so on.

INPUT SIZE: 0-200mm

CAPACITY: 45-900T/h

Our company provides a great capability in the design and manufacture of vibrating screens for a wide range of duties. Vibrating screen is usually used to separate materials into various sizes for further processing. Vibrating screen also used as a supporting machine in stone crushing plant, or for end use, that depends on client's needing. Under the same specifications, it has larger processing capacity and higher screening efficiency compared to traditional screens. It is particularly applicable to heavy type, middle type and fine screening operations, and it is the ideal screening equipment for primary crushing, secondary crushing and finished materials.

Applications: mining, quarrying, metallurgy, building material, highway, railway and chemical industry.

Performance Working Principle

Performance

1.Since the screen adopts latest advanced design concept and manufacturing technique, The vibrating strength can reach the international advanced level. Further, the throughput, screening efficiency and capacity can get improved greatly.

2.Optimized Screen Box Structure Making Operations More Reliable.There is no welded point on the side plate, so it is free from risks of fracture. All connections among structural components of the screen box adopt torsional shear bolts which has stronger strength than the ring-grooved lock bolts.

3.Modular Design, Lower Maintenance Costs.The vibration exciter and the screen box frame of Vibrating Screen use modular structures. If there is a need for replacement, the modular vibration exciter can be taken down from the screen box to be disassembled quickly. The vibration exciter adopts special labyrinth seal design and grease lubrication which ensure its stable operation. Besides, spare parts have higher degree of general utilization. So, it is easier and quicker for later replacement of spare parts.

4.Stable Performance.Driving motor and exciter adopts flexible drive, makes the operation smooth and stable.

5.Extra-Long Service Life.The screen side frame is without any form of welding point, and the support seat adopts rubber spring. 400mm long feeding chute, 25mm thick rubber plate, and 5mm beam protection wrapper sheet, these component ensured the screen has extra-long service life.

Working Principle

Vibrating screen is mainly composed of screen box, spring support groups, bearing, vibrators, transmission, motor, transmission bearings and other components.Vibrating screen is a machine supported by springs , block eccentric vibration as the exciter source and generated excitation force by the rotation of the eccentric , So that the screen box circumferential consequent reciprocation. The material on the inclined sieve surface successive approximation in round bouncing tumbling motion, by repeatedly comparing with mesh, smaller than the mesh size of the material through the sieve, larger than the screen hole size of materials still on the screen mesh, thereby completing the screening process.
