Introduction
Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed by dewatering screens.

Working Principle and Application
To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
When the two vibrating motor that installed vertically on the dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force will cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.
Dewatering screen is widely used in coal industry, ore industry, electricity industry metallurgy industry, mining industry etc.

Advantages and Features
1. Low noise, easy maintenance
2. Stable structure with strong exciting force
3. High screening efficiency and low noise pollution
4. Light weight, easy to disassemble and replace
5. Stable structure and strong exciting force
