Product Details

Dewatering Sieve (Vibrating Dewatering Screen)

The Dewatering Sieve is a high-frequency vibrating screen designed for reducing the moisture content of sand, tailings, and coal slime. It features a unique Negative Inclination (climbing) angle.

It is the standard equipment for dry discharge of Tailings and final dewatering of washed sand in Silica Sand Plants, achieving a final moisture as low as 12-15%.

Working Principle: Climbing Dehydration

Dual motor synchronization creates a linear force to throw water off.

Feeding & Filter Layer

Slurry is fed onto the steep back section (45°). Water drains quickly. A thin bed of sand forms, acting as a natural filter for fine particles.

Climbing Movement

The main deck has a Negative Angle (-5°). The vibration force pushes the material to climb uphill, extending the dewatering time and squeezing out water.

Dry Discharge

Under high-frequency vibration, water passes through the PU screen mesh. The dry sand cake is discharged from the front end.

Dewatering Sieve Structure

Technical Choice: Dewatering Screen vs. Circular Vibrating Screen

Why can't I use a normal screen for dewatering?

Feature	Dewatering Screen (TS)	Circular Vibrating Screen (YK)
Motion Trajectory	Linear (Back & Forth).	Circular.
Deck Angle	Upward (+5°).	Downward (-15°).
Function	Water Removal.	Size Classification.
Frequency	High Frequency.	Standard Frequency.

Core Advantages

1. Durable PU Panel

Equipped with modular Polyurethane (PU) screen panels. They last 5 times longer than metal mesh and are non-blinding (resist clogging).

2. Dual Motor Drive

Uses two vibration motors with self-synchronization technology. This ensures stable linear motion and allows for adjustable vibration amplitude.

3. Reinforced Body

The screen box is riveted (no welding stress) and made of thickened steel plate to withstand high G-force vibration without cracking.

Typical Applications

● Sand Washing Plant:
Final dewatering of silica sand or construction sand after the Sand Washer.
● Tailings Dry Discharge:
Reducing tailings moisture to allow for dry stacking and water recycling. See Tailings Solution.
● Coal Slime Recovery:
Recovering fine coal from washing water in Coal Preparation Plants.
● Potassium Feldspar:
Dewatering feldspar concentrate after flotation and magnetic separation.

Frequently Asked Questions (FAQ)

Q: What is the final moisture content?

A: For clean sand, it can reach 12-15%. For fine tailings, it is usually 15-20%. The material is dry enough for conveyor transport.

Q: Can I use steel mesh instead of PU?

A: Yes, Stainless Steel mesh is available for high-temperature or special applications. However, PU panels last much longer and are standard for sand dewatering.

Q: Is it suitable for very fine mud?

A: Yes, but you need a Hydrocyclone before the screen to thicken the feed. The screen works best with high-concentration feed (above 40% density).
