Product Details

High Frequency Vibrating Screen (Fine Screening & Dewatering)

The High Frequency Vibrating Screen is the ultimate solution for Fine Screening (0.1-5mm) and Dewatering of mineral slurries. It is widely used in Coal Preparation Plants and Metal Mines.

Typically fed by a Slurry Pump, it utilizes high-frequency vibration (up to 3000 RPM) to break the surface tension of the slurry, achieving rapid stratification and efficient dewatering of fine particles before tailings disposal.

Working Principle: High Frequency Stratification

High frequency and low amplitude vibration force the material to stratify quickly.

Rapid Stratification

The high G-force separates the slurry. Fine particles (water) sink to the bottom (contacting the screen), while coarse particles float on top.

Breaking Surface Tension

The intense vibration breaks the water tension, allowing water to pass through the fine mesh easily, achieving Deep Dewatering.

Transport

The solids are transported forward to the discharge end, while the water and slime pass through the screen as underflow.

High Frequency Vibrating Screen Structure

Technical Choice: High Frequency vs. Standard Screen

Why choose High Frequency for fine materials? Here is the comparison:

Feature	High Frequency Screen	Standard Vibrating Screen
Frequency	High (3000 RPM).	Low/Medium (800-1000 RPM).
Amplitude	Low (1-3mm).	High (5-10mm).
Application	Fine Slurry & Dewatering.	Coarse/Medium Sizing.
Efficiency	High for < 1mm particles.	Low for fine particles (blinding).

Core Advantages

1. High Efficiency

The high frequency vibration increases the probability of fine particles passing through the mesh, boosting efficiency by 50%.

2. Durable Polyurethane Mesh

We use premium Polyurethane (PU) screen panels, which last 5 times longer than metal woven mesh and are anti-clogging.

3. Adjustable Angle

The inclination angle can be adjusted to control the flow speed and dewatering effect according to your material.

Typical Applications

● Mineral Processing:
Classifying grinding circuit discharge (replacing Hydrocyclone) in Ball Mill circuit.
● Tailings Dry Stacking:
Core equipment for Tailings Reprocessing Solution.
● Coal Preparation:
Recovery of fine coal (coal slime) and dewatering.
● Aggregate Washing:
Removing fine clay and silt from construction sand.

Frequently Asked Questions (FAQ)

Q: How does it differ from a dewatering sieve?

A: Dewatering Sieve uses linear vibration for final dewatering (thicker cake). High Frequency Screen uses high speed vibration for fine separation and thin slurry dewatering.

Q: What is the lifespan of the PU mesh?

A: Our Polyurethane mesh panels typically last 6-12 months, which is 3-5 times longer than traditional stainless steel mesh. They are also easier to replace.

Q: Can I adjust the vibration intensity?

A: Yes. With a variable frequency drive (VFD), you can adjust the motor speed to control the vibration frequency, optimizing performance for different slurry concentrations.
