Dewatering Screen


Dewatering screen aka sand dewatering machine is the most suitable machine for sand dewatering process. They are designed as linear vibrating screen that widely applicated to dewatering, desliming, sculting, washing, degritting and screening. Dewatering screens as the most widely used dehydration product, which are mainly to produce a consistent dripless finished product and handle sand, gravel, aggregates, artificial sand, sea sand, clay, ores, tailings, coal, mining and other materials.

The deep bed design and high wearable polyurethane screen panel are adopted to dewatering screens, which can more effectively remove the more moisture. And depending on the gradation of material processed, dewatering screen will typically produce a finished product with water content as low as 8%, getting the highest possible percentage of final product. Dewatering screen can also recover fine solid particles from liquids as sand recycling system. The materials that greater than or equal to 200mesh more than 95% can be recycled and dewatered to dripless prior to stockpiling.

Working Principle

Dewatering screen adopts dual-motor self-synchronization technology. When working, materials are fed onto the screen surface at the feed end of dewatering screen to achieve a rapid dewatering. As the material piled up on the screen, a puddle began to form.

Under a reverse movement of two sets of vibrating motor in the same angular velocity, the inertial force produced by an eccentric block in a particular aspect to repeated stack or offset. So as to produce a great shock driving screen box along the straight line track to do periodic reciprocating motion, make the materials on screen from input to output to do gradually vibrate and water is separated from materials and pass screen hole and drop to water tank. Solids on screen surface are moving towards the outlet end of screen and conveyed to stock pile.
