It is the use of large amplitude, large vibration intensity, low vibration frequency and a variety of self-cleaning screen surface to complete the wet coal screening process. The traditional sieving theory holds that the sieving process is divided into three stages: loose, stratified, and sieved. Loose is the prerequisite for stratification.

As the screen vibrates, the material moves along the deck and under a water spray that rinses the coal. The liquid and fine coal particles pass through the gaps in the screening deck as the material flows toward the discharge end of the screen. Finally, the rinsed coal falls off of the discharge end of the screen to continue with further ...

According to the annual census of coal preparation plants conducted by Coal Age [], the USA operates 286 coal preparation plants in 12 states.This number is relatively small by comparison to the worldwide fleet which is estimated to be 2,283 plants [].The capacity of the plants can range from less than 200 t/h for small operations to 6,000 t/h or more for …
