Custom Screening And Packaging Machinery. Multi-Level Vibrating Screen For Refined Salt, Automatic Packaging Machine For Refined Salt Products, Service
Product Description
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 manufactured from food-grade stainless steel and is equipped with heavy-duty vibrating motors, featuring high screening efficiency, stable operation, and easy maintenance, making it suitable for salt plants of all sizes.
Equipped with 2 to 4 screen layers (customizable mesh size 0.1 to 10 mm), facilitating the classification of coarse, medium, fine, and powder salt in a single continuous pass.
Delivers exceptional accuracy rates ranging from 95% to 99%, with an adjustable vibration amplitude engineered to prevent material clogging.
Combines high-frequency vibration with food-safe rubber/polyurethane cleaning bouncing balls to substantially minimize salt agglomeration and screen blinding.
Accommodates throughputs of 1 to 50 tons/hour; built with a reinforced structural frame and rubber shock dampers ensuring minimal noise and prolonged service lifespan.
Integrated quick-release clamps enable screen mesh replacement without tools; exterior motor configuration allows convenient routine service checks during operation.
A tightly sealed dust cover configuration eliminates dust escape and prevents cross-contamination, complying fully with environmental and hygiene regulations.
Working Principle
The dried salt is evenly fed onto the top screen surface via a vibrating feeder. Dual synchronized vibrating motors produce linear or elliptical motion dynamics, spreading the material uniformly across the screen deck. Particles smaller than the aperture dimensions easily pass through the mesh layers, while oversized particles and foreign impurities are continuously directed toward their respective discharge outlets. The advanced multi-deck configuration facilitates the simultaneous separation of 2 to 4 specific particle grades, while continuous high-frequency vibrations disintegrate loose agglomerates, ensuring an uninterrupted and optimized classification workflow.

Frequently Asked Questions (FAQ)
The equipment is built using high-grade food-safe stainless steel (such as SUS304 or SUS316L) for all product contact surfaces to prevent corrosion caused by salt, while the structural base is engineered with high-strength carbon steel for robust vibration dampening.
The system combines precision high-frequency vibration with an integrated bouncing ball self-cleaning mechanism (food-grade rubber or polyurethane), which continuously strikes the screen deck from below to dislodge trapped salt granules and mitigate mesh blinding.
Yes, both the screen dimensions (lengths ranging from 2m to 6m, widths from 1m to 3m) and mesh sizes (ranging from 0.1 mm to 10 mm across 2 to 4 decks) can be fully customized according to your line capacity and classification requirements.
The production line can integrate automated packaging machinery supporting small consumer retail packs (500g to 5kg), commercial bags (10kg to 50kg), as well as jumbo bulk ton bags (1000kg), alongside provisions for manual packaging lines.
Maintenance is designed to be tool-free and rapid. Equipped with fast-release screen clamps, operators can replace screen decks in minimal time without extensive downtime, and the externally mounted vibrating motors facilitate direct maintenance access.
