The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle. To calculate the bed depth of the material, the following formula is used.
In the coal industry, the role of vibrating screens is not only to classify, most of the vibrating screens are also used for dewatering or de-intermediation of coal, and even for desilting. In the coal preparation plant's screening operations, raw coal preparation and product processing, it is mainly divided into five categories.
The present study involves the analysis of the screening performance of the new vibrating screen with the coal feed of varying moisture content of 4%, 6% and 8%. The maximum screening efficiencies obtained for screening the coal feed with the moisture contents of 4%, 6% and 8% were 85.96%, 77.84%, and 68.27%, respectively. ...
The application practice and effect of flip flow screen on raw coal screening, desliming before lump and slack coal separation, dehydration and sculping of slack coal are comprehensively introduced. The undersize fraction and the oversize fraction are simultaneously decreased because of the application of flip flow screen on raw coal …
Polyurethane screen plate is a kind of mesh screen produced by polyurethane as raw material, which is suitable for screening materials of various nature, as well as coal, gangue, coke, slaked lime and other materials that are wet and easy to block.

Screening of coal is one of the processes carried out to produce clean coal suitable for the blast furnace. In this work, the screening of moist coal was carried out for different angles of the screen and frequencies. A 2 mm screen perforation was used to separate undersize coal of size +1 mm-2 mm from the +1 mm-3 mm coal samples.
