Application of Vacuum Horizontal Belt Filter Cloth in Dewatering

In mining production, tailings dewatering is a key step in resource recovery and environmental protection. With its automated continuous operation, the vacuum horizontal belt filter delivers high-efficiency solid-liquid separation. It is widely used for tailings dewatering in the mining industry. As a core component of the filter, horizontal belt filter cloth is broadly applied to dewater various metallic ores, non-metallic ores, and industrial by-products.

1.Wide Range of Applicable Materials

Vacuum belt filter cloth can meet the dewatering requirements of slurries with different particle sizes. Typical applications include:

Mining dewatering: such as iron concentrate, and lithium mica, making transportation and further processing easier after filtration;

Tailings dry discharge: dewatering of iron, copper, and gold tailings to reduce tailings storage area and lower environmental pollution risks;

Industrial by-product treatment: such as fly ash and desulfurization gypsum, enabling resource utilization of solid wastes.

2.Technical Advantages and Working Principle

The vacuum horizontal belt filter uses high-strength polyester (PET) or polipropilene (PP) filter cloth, combining vacuum suction and mechanical pressing for efficient dewatering:

Continuous automated operation: slurry is evenly distributed onto the filter cloth and moves with the conveyor belt; in the vacuum suction zone, rapid dewatering occurs without manual intervention;

High-efficiency solid-liquid separation: the microporous structure of the filter cloth precisely matches the particle size of the material, ensuring rapid liquid passage while retaining solid particles;

Low energy consumption and minimal maintenance: maintains stable performance during long-term continuous operation, reduces clogging, and lowers replacement costs.

3. Industry Application Prospects
With the mining industry moving towards greener and smarter operations, vacuum belt filter cloth has significant potential in the following areas:

Fine particle tailings dewatering (such as lithium mica and rare earth ores);

High-corrosion material handling (such as acidic slurry and chemical residues).

Conclusion
In the future, with the development of new composite filter cloth materials, the application range of horizontal belt filter cloth will further expand, contributing to the sustainable development of the mining industry.
