Traditional salt sieving mainly relies on manual work or simple equipment, which comes with multiple drawbacks. Manual sieving delivers low efficiency and poor precision, and foreign matters such as hair and gravel tend to mix into finished products. Dust flies everywhere during operation, polluting the workshop and causing material waste. Conventional sieving equipment is poorly adapted to salt materials. Given that salt easily absorbs moisture and forms lumps, screen clogging, material cross-contamination and incomplete classification frequently occur. It is difficult to stably produce salt products with varied particle sizes, hindering the scaled and standardized production of enterprises.
Gaofu multi-layer grading rotary vibrating sieve is developed based on the physical properties and actual working conditions of salt. Optimized in structure, material and sieving principle, it fully meets the demands of fine salt classification. It helps manufacturers get rid of the inefficiency and roughness of traditional sieving methods, and build efficient, stable and clean grading production lines.
1. Multi-layer Screen Structure for Multi-size Grading in One Go
The sieve is equipped with 1 to 5 customizable screen layers. A single feeding process can separate salt into 2 to 6 finished products with different particle sizes, including coarse salt, medium salt, fine salt and superfine powder. The sieving precision remains steadily above 95%.
The mesh count can be adjusted as required, covering a full range from 20-mesh coarse salt to 200-mesh fine salt. It satisfies the particle size standards for edible salt, industrial salt, seasoning salt and other applications. A single unit can produce multiple products simultaneously, greatly enhancing production flexibility and added value.
2. Three-dimensional Vibration Technology for High Efficiency and Anti-clogging Performance
A vertical vibration motor serves as the vibration source. The eccentric weights at the upper and lower ends convert rotational motion into three-dimensional vibration in horizontal, vertical and inclined directions, enabling salt to move in a spiral pattern on the screen surface.
The built-in bouncing ball self-cleaning system (ultrasonic anti-clogging device is optional) continuously taps the screen mesh during operation. It effectively prevents mesh clogging caused by moisture absorption and caking of salt, keeping the screen unobstructed all the time and reducing unnecessary shutdowns for cleaning. Its continuous working efficiency is over three times higher than that of traditional equipment.
3. Food-grade Materials with Excellent Safety and Corrosion Resistance
All components in direct contact with salt are made of 304/316L food-grade stainless steel with fine polished surfaces. Free of burrs and material accumulation dead corners, the material features outstanding resistance to salt corrosion and releases no heavy metals, fully complying with food safety production standards.
The fully enclosed structure stops dust leakage, cutting down material loss and preventing external impurities and moisture from contaminating salt. It also creates a cleaner working environment for the workshop.
Five Core Advantages to Help Salt Enterprises Reduce Costs and Improve Efficiency
1. Wide Capacity Range to Support Large-scale Production
Available in a complete range of models, this rotary vibrating sieve has an hourly output of 1 to 15 tons, suitable for production demands from small workshops to large salt processing plants.
With a compact structure, the equipment can be installed in series or parallel connection. It can be easily linked with belt conveyors, elevators and other equipment to integrate seamlessly into automated production lines and realize continuous operation, maximizing production capacity.
2. High Sieving Precision for Stable Product Quality
The sieve effectively removes dark spots, gravel, lumps and fine impurities from raw salt. The processed salt features uniform particle size and neat appearance, keeping the defective rate at a very low level. Consistent grading performance ensures uniform quality across all batches of products and strengthens enterprises' market competitiveness.
3. Low Energy Consumption to Cut Long-term Operating Costs
Driven by optimized vibration motors, the equipment reduces energy consumption by more than 30% compared with traditional sieving machines. Its operating noise is controlled below 75 decibels for an eco-friendly working environment. Featuring a robust structure and few vulnerable parts, it enjoys a long service life and lowers long-term maintenance costs significantly.
4. Easy Screen Replacement and Simple Maintenance
Adopting a parent-child screen separation design, the screen can be replaced by one worker within just 3 to 5 minutes without professional tools. It shortens downtime for product changeover and adapts to varied particle size production requirements quickly. The equipment is easy to disassemble and clean with no sanitary dead corners, meeting the frequent cleaning requirements of the food industry.
