Vibrating Screen

The determination of structural parameters of vibrating sieve sieve surface, can from the following four ways:
1. The screen surface length and width
It is generally believed that screen surface width directly affect the productivity and the length of the screen surface directly affect the screening efficiency. Wide screen surface, effective area, productivity; Screen surface is long, the material stay on the screen when asked long, through the sieve more opportunities, high screening efficiency. But it is not as long as possible, because the screening efficiency and material in the whole screen experience is complex, the relationship between the start time, due to the fine grained material on the surface of the screen is more, through sieve probability per unit time is bigger, through sieve probability is higher, when after a certain time, stay on the surface of the sieve material particle size mostly near the size of a mesh screen material hard, even if the material stay on the screen for a long time (i.e., the sieve surface length big and it is hard to increase material through sieve probability, thus results in the decrease of sieve machine work efficiency. For screening efficiency, in fact, the screen surface width screen surface length for screening ability also has different degree of ring, the match is very important also, general wide long than l: 2 ~ l: 3 is advisable.

2. The mesh shape
Although mesh shape depends mainly on screening product size and demand for undersize purposes, but also have certain influence to screening efficiency. Circular mesh compared with other shape of the mesh, in the case of the same nominal size, under through the screen mesh size smaller, for example through the circular mesh particle average maximum particle size only through the same size of the square mesh particles of 80% ~ 85%; And rectangular mesh screen surface effective area is big, the screen surface quality is light, large production capacity, at the same time, through the mesh material granularity than through the nominal size of the same circle and square mesh material particle size.
Therefore, in order to get higher rates of screening efficiency, must according to different sieve material choose different mesh shape. Choose a square mesh, such as processing block material handling should choose rectangular mesh plate materials; Dry screening with a square hole, wet sieving using circular hole. This can improve the processing ability of vibrating screen.

3. The mesh size and mesh opening rate below
In the case of screening material must, mesh size had a great influence on screening efficiency. The mesh size, the greater the material through sieve ability stronger, the greater the processing power of vibrating screen also. Mesh size, of course, is mainly composed of is determined by the technological requirements of sieve material. On the surface of the sieve hole opening rate refers to the screen surface area and screen surface area ratio (also called coefficient) effectively. Opening rate high, increasing the probability of material particles through the sieve, sieve processing capacity is high. On the other hand, the vibrating screen processing capacity is low. Therefore, in order to improve the efficiency of screening, should choose effective coefficient larger screen surface.

4. The screen surface materials
Non-metallic screen surface, such as sizing screen surface of rubber, polyurethane type sizing screen surface, polyurethane to sew sieve surface, nylon sieve surface, etc., due to the nature of the non-metallic materials, second in the process of screening high frequency vibration, it is difficult to make blocking phenomenon occurs, is advantageous to the material through sieve, than metal sieve sieve surface processing efficiency improved.
