The screening equipment commonly used in beneficiation

In the production process of beneficiation, after the material crushing and grinding effects Then they also need to use screening tool to mix materials of different particle sizes into various levels of granularity There are many screening equipment type that concentrator commonly used , such as fixed screen, vibrating screen, cylindrical screen, fine screen and roller sieve Properties of materials, the beneficiation process requirements, performance of the screening equipment, as well as onsite job’s application conditions must be considered when selecting the screening equipment, the vibrating screen is the most common choice in concentrator And the vibrating screen is also major screening equipment in Liming Heavy production Here are the characteristics and applications of several popular screening equipment for reference

1 The vibrating screen
The vibrating screen box have different trajectories, can be divided into linear vibrating screen, circular vibrating screen, vibrating screen fine three Here we mainly introduce the Circular Vibrating Screen: circular vibrating screen is a kind of do circular vibration, multiple layers, efficient new shaker Circular vibrating screen adopts the barrel type of eccentric shaft vibration exciter and partial block help to adjust amplitude, screening specifications, reliable structure, strong exciting force, high efficiency, low noise and durable, easy maintenance, use of safety features the shaker is widely used in mining, building materials, transportation, energy, chemical industry products classification

2 Fixed sieve
Fixed sieve contains grizzly screen and bars sieve grizzly screen used for ore by crushing ore bin or coarse ore bin upper ore particle size as a control with, usually installed horizontally Article sieve used for prescreening coarse crushed or broken before the mesh is generally not less than 50mm Article crusher installed in front of the screen at the same time play the role of the runner, which angle is generally 4050 °, if the ore containing mud water a long time, can increase the inclination 510 °

3 The curved sieve
The curved sieve generally used for wet classifying fine materials , dehydration, heavy media beneficiation sculping job Its structure is simple, lightweight, small footprint, no moving parts, large capacity, high separation precision, easy to plug the sieve, sieve product moisture but high screen bar wear quickly, even to the mining claim and take some pressure

4 Roller Screen
The coarse material commonly used Roller Screen screening, feeding maximum particle size of up to 500mm, suitable for screening large lump coal, limestone and shale, but also for washing machine or to the mining machine to use High efficiency roller sieve, sieve material was too crushed small, small mounting height; but the more complicated structure, heavy, hard roller wear faster when screening material Metal mines currently being replaced by more heavy vibrating screen
