Polyurethane Mesh Linear Vibrating Screen Vibratory Sieve Sifter Equipment

Introduction

The dewatering vibrating screen adopts seat or flange exciter, which is driven by two motors in the opposite direction and rotates synchronously. The self-synchronization technology is driven by two motors. The exciter is driven by a winding coupling. When the two groups of exciters rotate synchronously and reversely, the exciting force produced by the eccentric block cancels each other in the direction parallel to the axis of the motor and is perpendicular to the axis of the motor. The two axes have an inclination to the screen surface. Under the action of the excitation force, the screen box moves in a reciprocating straight line. The material is thrown up and jumped forward in a straight line motion. At the same time, the V-shaped structure of the screen surface can achieve better dehydration effect

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.
