What is the purpose of a dewatering screen?


Overview of the Dewatering Screen:
  Dewatering screen is also called drainage screen, drainage sieve, dehydration vibrating screen,
dewatering vibrating screen, vibrating dewatering screen, dehydration shaker, sculping screen,
medium drainage screen, medium draining screen, sizing-medium drainage screen etc.
  Then what is the purpose of a dewatering screen? The dewatering screen is often used in coal preparation,
ore dressing, power generation, sugar making, salt making and other industrial sectors, for medium and fine
grained materials wet and dry grading, screening, dewatering, medium removal and desliming.
This kind of screening machine can choose vibration motor or exciter as vibration source.


Vibration Motor Type Dewatering Screen


Vibration Exciter Type Dewatering Screen

Features of the Dewatering Screen:
  1. Low noise, easy maintenance.
  2. Reasonable structure, strong and durable.
  3. Good dewatering effect, safe and reliable.
  4. High screening capacity and efficiency.
  5. Screen has a simple structure, easy maintenance. Screen adopts high strength metal woven mesh,
durable service, or uses polyurethane screen mesh.
  6. It has seat type and hanging type for choice.
 
Working Principle of the Dewatering Screen:
Dewatering vibrating screen adopts dual motor self-synchronization technology, universal eccentric block 
and adjustable amplitude vibrator. It is mainly composed of screen box, vibration exciter, supporting system and motor.
  It drives two non-contact vibrators to do synchronous reverse running respectively through the tape coupling.
The centrifugal force which is produced by two sets of eccentric mass superimpose along the vibration direction of component force.
Reversed centrifugal force counteract, forming a single vibration exciting force along the direction of vibration, so as to make
the screen box do reciprocating linear motion.

Ordering Instructions of the Dewatering Screen:
1. The screen structure (weaving, punching, wedge-bar), mesh size, processing capacity, material name and feeding particle size
should be indicated in the selection and ordering by the user.
2. When selecting and ordering, the user should determine the arrangement of the sieve and screen seam size. If they do not make
a decision, we supply the machine according to the right-type screen seam 0.5mm arrangement. (The motor is installed on the
left or right side of the material flow direction.)
3. The dip angle of the screen surface can be adjusted from -2 to 10 degrees. Other angles can be adjusted by the user.
4. When the forced synchronization is adopted, the motor can be installed on the left or right. User must state when ordering.
