Over 10,000+ customers' choice, Focus on screening industry 40+ years
Salt screening dust generation mainly originates from the following factors:
High fines content. Salt processing generates a certain proportion of fines (typically below 80 mesh). These fines easily escape through equipment gaps during screening.
Insufficient equipment sealing. Traditional screening equipment often lacks adequate sealing – gaps between screen and frame, discharge port connections, and other locations become channels for dust escape.
Open operation. Some screening equipment uses open designs for feed and discharge – material is directly exposed to workshop air during entry and exit, allowing dust to disperse.
Gaofu's enclosed dust‑proof salt rotary vibrating sieve features a fully enclosed structure that physically blocks dust dispersion paths:
Enclosed screening chamber – dust has nowhere to escape. The screening process takes place in a completely enclosed chamber – from feed inlet to discharge outlet, material is isolated from workshop air throughout. Fine salt dust cannot escape from equipment gaps and must be processed within the enclosed space.
Tight seals eliminate leakage points. All connections use high‑quality seals to ensure system airtightness. Discharge ports, access doors, inspection windows, and all potential leakage points are sealed.
Negative‑pressure dust collection interface – active dust capture. The equipment can be equipped with a negative‑pressure dust collection interface for connection to the workshop dust extraction system. Trace dust generated during screening is directionally drawn by negative‑pressure airflow to the dust collection system for active capture.
Gaofu's enclosed dust‑proof salt rotary vibrating sieve's fully enclosed design delivers multiple practical improvements for salt processing workshops:
Significantly improved workshop environment. The fully enclosed structure effectively controls salt dust emission – workshop dust concentration is greatly reduced. Walls and equipment surfaces no longer accumulate salt frequently, and cleaning cycles are significantly extended.
Greatly reduced material loss. Salt dust no longer escapes from equipment gaps – every grain of salt is effectively collected. Impurities and oversize material are automatically discharged from the reject outlet, while on‑spec salt is precisely collected from the discharge port – reducing material waste.
Extended equipment life. Salt dust no longer adheres to external equipment structures, reducing salt corrosion impact on equipment. Equipment operating in a clean environment with less external rusting enjoys longer service life.
Compliance with environmental and food safety requirements. The fully enclosed structure ensures no dust emission, low noise, and reasonable energy consumption – meeting environmental requirements. At the same time, the enclosed environment prevents foreign matter from entering the material, complying with food production hygiene standards.
Improved operator working conditions. Operators no longer need to work in a salt‑dust‑filled environment – avoiding respiratory irritation and skin corrosion from salt dust.
Does fully enclosed design compromise screening efficiency? Gaofu's enclosed dust‑proof salt rotary vibrating sieve provides the answer:
Screening accuracy is unaffected. The fully enclosed structure does not affect material screening trajectory or pass‑through efficiency. The three‑dimensional vibration fully disperses and stratifies material on the screen, with screening accuracy reaching over 90%.
Continuous operation is uninterrupted. The fully enclosed structure supports continuous operation – no need to stop frequently for dust‑related cleaning. Impurities and oversize material are automatically discharged, allowing long‑duration stable operation.
Flexible discharge orientation. Discharge ports can be rotated 360° around the axis – while maintaining full enclosure, the discharge direction can be flexibly adjusted according to workshop layout.
Gaofu's enclosed dust‑proof salt rotary vibrating sieve is suitable for the following salt processing scenarios:
Edible salt refining workshops: production environments with strict cleanliness requirements;
Sea salt processing plants: high salt dust content during sea salt screening needs effective control;
Industrial salt production workshops: large‑volume industrial salt screening balancing efficiency and environmental protection;
Salt chemical raw material pre‑treatment: pre‑screening of salt‑based chemical raw materials.
Dust control in salt processing workshops cannot rely on end‑of‑pipe measures like "wearing masks" or "frequent cleaning." The solution lies at the source – preventing salt dust from ever having the chance to disperse into workshop air. Gaofu Machinery's enclosed dust‑proof salt rotary vibrating sieve – with its fully enclosed structure, tight seals, and negative‑pressure dust collection interface – systematically contains salt dust within the screening chamber, providing salt processing workshops with a clean, efficient screening solution.
