The dewatering screen is mainly used for dehydration, desliming and medium removal and can be used for washed-out sand in sand and gravel plants, coal slime recovery in coal preparation plants and dry discharge of tailings in dressing plants, thus it is also called as sand and gravel dewatering screen, mine dewatering screen, coal slime dewatering screen, tailings dewatering screen, high-frequency dewatering screen, etc.

Although they all fall into dewatering equipment, the structure of the dewatering screen is still somewhat different when applied to different materials. The sand and gravel dewatering screens used on the washed-out sand production lines and the tailings dewatering screens commonly used in dressing plants are different types of equipment.
