Dewatering screen

Dewatering screen

Vibration dewatering screen, the main role is dewatering, desFodamon, desulfurization, can be used for sand washery, coal preparation plant slurry recovery, tailings dry drainage and so on, so also called sand dewatering screen, mine dewatering screen, slime dewatering screen, tailings dewatering screen, high-frequency dewatering screen.
1. Matching of dewatering screen and sand washing machine.
We should know that the sand washed by sand washing machine is not very clean, and the sand is too muddy and wet (water content is large), and does not meet the production needs of low mud content and high standards. Therefore, desiccant screens are needed. Sand and stone are washed by sand washing machine, and then are washed by vibrating dewatering screen, hydraulic grading, desFodamon and dewatering. Reasonable particle size ratio is achieved, and the mud content is reduced to less than 0.7%.
2. Vibration dewatering screen is used alone.
Vibrating dewatering screen can also be used alone when it acts on some materials with low mud content, and no sand washing machine, such as quartz sand, is needed. Because of the low mud content of quartz sand, washing sand with sand washing machine not only consumes energy but also has poor effect. It is very important that the investment cost of dewatering screen is lower than that of sand washing machine.

Working principle

The dewatering vibrating screen adopts double motor self synchronizing technology, universal eccentric block and adjustable amplitude vibrator. It is mainly composed of screen box, vibration exciter, supporting system and motor. Through belt coupling to drive two unrelated vibrators to run synchronously and backward respectively, the centrifugal force produced by two eccentric masses superimposes along the vibration direction and counteracts by reverse centrifugation, thus forming a single exciting vibration along the vibration direction and making the screen box move in a reciprocating straight line. The water tension on the surface of the pulp is changed by the exciting force. The pulp water passes through the screen and becomes the bottom of the screen. The fine material is blocked by the screen to form the filter layer and is discharged forward by the vibration force.
