product details

Technical Characteristics

Vibrating screens are key equipment in salt washing production, used for precise particle size classification, impurity removal and dehydration. They handle large volumes of washed and dried salt, ensuring uniform particle size, high purity and stable final salt quality. The equipment is made of food-grade stainless steel and is equipped with heavy-duty vibrating motors, featuring high screening efficiency, stable operation and easy maintenance, suitable for salt plants of all sizes.

High-efficiency grading and screening play a unique role in the salt washing processing line:

Multi-layer precision screening

2 to 4 layers of screen (customizable mesh size 0.1 to 10 mm), allowing for the classification of coarse salt, medium salt, fine salt and powder salt in one pass.

High screening efficiency

accuracy rate up to 95% - 99%, adjustable amplitude to prevent clogging.

Anti-clogging self-cleaning

high-frequency vibration + rubber/polyurethane cleaning balls, reducing salt clumping and screen clogging.

Large capacity and durability

output 1 - 50 tons/hour; heavy-duty carbon steel frame, equipped with rubber shock absorbers, low noise, long service life.

Easy maintenance

quick-release screen clamps, screen replacement without tools; external motors can be maintained during operation.

Fully enclosed design

dust cover prevents cross-contamination, meeting environmental protection requirements.

Working Principle

The dried salt is evenly fed onto the top screen surface through a vibrating feeder. The dual vibrating motors generate linear/elliptical motion, which evenly spreads the salt on the screen surface. Particles smaller than the screen holes pass through the holes, while oversized impurities or large particles are discharged. The multi-layer screen design can simultaneously separate 2 to 4 different particle sizes. The high-frequency vibration of the screen surface can break up lumps, ensuring continuous and efficient screening.
