The screening operations of the mobile waste rock and coal screening crusher is an important link in the coal washing and processing course, the screening efficiency of the waste rock and coal not only affects the product quality of the thermal coal and coking coal,but also affects the environmental protection and the improvement of the economic efficiency of the enterprise.It is the essential equipment in the mining, chemical plants, cement factories ,etc.Now,we will analyse how to improve the crushing efficiency of the waste rock and coal screening mobile crusher.
1. Choose large size sieve
Choosing the large sieve to make the mobile waste rock coal sieving crusher increas the motivation and amplitude of the vibration, which makes the the impact and the shear stress that the sieve plate act on the materials increase, overcomes the adhesion between the ore grains, reduces the sieve surface jams,completes the loosening, layering and sieving of the materials to be sieved rapidly,improves the operating conditions of the sieve, and improves the screening efficiency.
2. Choose a suitable mesh shape
In order to improve the screening efficiency, you must choose different suitable mesh shape according to different materials.Choose a square mesh, when processing the block materials,choose rectangular mesh,when handling with the tabular materials. In the case that the materials are certain, the mesh size has a great influence on the screening efficiency.
3. Use the proper screen surface inclination
Adopting the appropriate screen surface inclination can control the flow velocity of the materials on the screening surface, which makes the materials stay on the screen for a long time, generally the movement speed of the materials on the screen should be controlled below 0.6 m .Moreover,the appropriate angle is beneficial to reduce the thickness of the materials , and realize the high screening efficiency.
