Hi Jim. Thank you for your question.

　　Coal shale shaker is affected by a variety of factors during the screening process, which will lead to low screening efficiency and unsatisfactory screening effect. The factors affecting the screening efficiency of coal shale shaker are briefly introduced as follows:

　　1 Water content of coal

　　When the water content of coal is high, the viscosity of coal will increase, and the binding material will block the screen hole, make the screen hole become small, greatly affect the production efficiency.

　　2 Effect of coal particle size

　　If the coal contains a large number of particles similar to the size of the sieve, the screening efficiency will be greatly reduced.

　　3 Length and width of screen

　　The width of screen surface affects the output of coal screening, and the length of screen surface affects the accuracy of coal screening. However, the effect of increasing sieving efficiency is not remarkable when the sieves are too long.

　　4. Inclination of screen surface

　　The larger the dip angle of the screen surface, the faster the material flow rate, the greater the processing capacity; the smaller the dip angle, the longer the stay time of the material on the screen surface, the higher the screening accuracy. The inclination angle of the screen surface is related to the structure of the screen and the quality requirements of the screened products.
