High-efficiency and multifrequency dewatering screen

Introduction
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water contained in particles. High-efficiency and multifrequency dewatering screen can enable ore handling and make concentrates be transported easily, allow further processing to occur and to dispose of the gangue.
Features
High-efficiency and multifrequency dewatering screen has special design, especial suitable for processing fine particle minerals. It has large dealing quantity, can make complete dewatering. It has remarkable technical and economic effect.
Application
Xinhai multi-frequency dewatering screen adopts unique design, we can get unexpected effect when combined with Xinhai XCⅠ、XCⅡ cyclone and Xinhai high-efficiency thickener (deep corn, multi-cone). It can be widely used in discharging dried tailings, fine mineral dewatering, chip removing, carbon-in-pulp separation etc.
Working principle
The product adopts double vibration motor as power supply. The double vibration is installed parallel, when they are running at the same time, centrifugal force is produced by two groups of eccentric block. Centrifugal force along the direction of vibration is superposed, otherwise it is offset. Thus form a single centrifugal force which along the direction of vibration, which makes screen box affectation reciprocating linear motion.
