Product Description

Xinxiang Mining Ore sieve shaker Mining Machine Circular Vibrating Screen

Introduction 
Circular Vibrating Screen is a kind of new and highly effective vibrating screen which can be designed with multiple layers. It is composed of screen box, screen mesh cloth, suspension (or support) device, bottom frame and motor. Circular vibrating sieve is available for smelting , quarry , coal preparation, ore dressing, energy, power, chemical, construction material industries.



Application
The circular vibrating screen is widely use for larger ore, iron ore, stone, urea, potash, pellet, activated carbon, coal, aluminum powder, copper ore, alloy ore , limestone, kaolin, calcium carbonate those metallurgy, mining, chemical, building material, grain, fire-proof industries.


Working principle
The vibrating exciter eccentric block and shaft of circular vibrating screen driven by motor are rotating with high speed. Motorial eccentric block occurs large centrifugal force, motivating the screen box move in circle. The material does parabolic motion,  and the size of material is less than the screen mesh so that material can pass the screen mesh to make it separate.
This motion to make the mineral separate equipment be used very well in large granular size, especially for mineral.

Advantages and Features 
1.Simple structure, easy maintenance, stale operation, high production yields;
2.Adopt punching sieve or steel sieve mesh in order to prevent blockage;
3.Sieve beam and screen box adopts high strength bolt connection, no welding processing;
4.Adopt perforated sieve plate to prolong mesh service life and prevent mesh blockage;
5.Rubber vibration spring to reduce noise pollution and provide smooth vibration operation;
6.Large dip angle structure enables high screening efficiency and handling capacity;
7.Hooked riveting with lock rivert, advanced structure; sturday and durable.
8. Adopt special configuration, conform to personalized needs of the customer and meet the needs of different industries to achieve the best screening goal.
9.Motor brand can be domestic or imported: Yutong, Shuangyu, ABB, Siemens, WEG etc;
10.Bearing brand can be domestic or imported: C&U, LYC, HRB , WZS, FAG, NSK, SKF etc.

Features

Between the connection of circular vibrating screen's beam and screen box, it adopts high strength bolts;

It has simple structure so that can maintain it easily;

The mineral separator equipment adopts tyre coupling and flexible connection, running steady;

The circular vibrating sieve adopts eccentric shaft and block as the vibration source;

With strong vibrating exciting force, high frequency, large capacity, little amplitude and large angle, it can guarantee the high screening efficiency;

Low noise, energy conservation;

Eccentric shaft can be drived by motor through belt or motor through coupling.

Common Troubles and Maintenance

Vibrating screen is essential in manufacturing processes for many factories. In general, when circular vibrating screen goes wrong, the whole production line will stop. In addition, the maintenance may delay the production. The following is the common troubles and maintenance of circular vibrating screen.

When circular vibrating screen cannot be started or in a low amplitude, reasons are the following: 1, Motor is damaged.
2, Electric components controlling the circuit are damaged.
3, Low voltage.
4, Too many waste sundries on screen cloth.
5, Vibration exciting goes wrong.
6, lubricating grease is agglomeration.

The concerning troubles are caused by mismanaging the clean-up and check the machine irregular. Therefore, replace the damaged components in time and check the machine regular, clean up the sundries produced by vibrating screen in time when machine finishes working.

Reasons of abnormal flow of materials are the following:
1, Machine body is instability as the stiffness of screen box is not enough.
2, Screen box is horizontal deflection.
3, Support springs are deformation or damaged.
4, Screen cloth is damaged.
5, Unbalanced feeding.
6, Beam is fracture.

When rotating speed of screen slows down and bearings are heating, follow the below methods.
1, Check the volume of lubricating grease in main bearing hole.
2, Inspect whether there is blocking of bearings. Clean up in time and replace the sealing components.
3, Check the oil in bearings.
4, Check whether bearings are damaged or poor installation.
5, Eccentric block on the wheel falls off, or sizes of eccentric blocks are different.

If the machine noise at work, check the following components.
1, bearing of vibration exciting.
2, fastening bolts.
3, the beam.
4, Support springs.
