Product Description


Product Description
主图3


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
Structure

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.

Advantages


  • Polyurethane screen is adopted because it longer service life than other types of screen, and it doesn’t block the holes

  • It can effectively reduce the loss of fine sand and control it between 5% and 10%

  • Different solutions can be designed according to your requirements

  • Reduce the stacking time of fine materials, and it can work directly to supply the market



Dewatering Screen FAQ – Common Issues & Solutions

1. What are the most common problems with dewatering screens?

Screen panel clogging/blinding – Fine particles stick to the mesh, reducing efficiency.

Excessive vibration/noise – May indicate unbalanced loads, worn bearings, or motor issues.

Water not separating properly – Could be due to incorrect screen angle, feed rate, or mesh size.

Premature wear of screen panels – Caused by abrasive materials or improper tensioning.

Motor or drive failures – Overloading, electrical issues, or lack of maintenance.


2. How to prevent screen blinding?

Use polyurethane or rubber screen panels (better for sticky materials).

Adjust spray bars (if equipped) to keep the screen clean.

Optimize feed rate – Too much material can cause clogging.

Choose the right mesh size for your material.


3. Why is my dewatering screen vibrating too much?

Unbalanced load – Uneven material distribution on the screen.

Worn-out bearings or springs – Check and replace damaged parts.

Loose bolts/fasteners – Ensure all components are securely tightened.

Motor misalignment – Verify proper installation and alignment.


4. How to improve dewatering efficiency?

Adjust the screen angle (steeper angles drain water faster).

Optimize vibration intensity & frequency (higher G-force improves dewatering).

Use proper screen media (wedge wire, polyurethane, or rubber panels).

Control feed consistency – Avoid overly dilute slurry.


5. How often should I maintain my dewatering screen?

Daily: Check for unusual noises, loose bolts, and screen wear.

Weekly: Inspect bearings, motors, and spray systems (if used).

Monthly: Lubricate moving parts and replace worn screen panels.
