Application of Vacuum Belt Filter in Mining Field
1. Core application scenarios
1) Dehydration of concentrate
Used for rapid dehydration of metal ore (such as iron ore and copper ore) concentrates, achieving efficient solid-liquid separation through vacuum negative pressure suction, increasing the solid content of concentrates for easy transportation and smelting.
2) Tailings dry discharge and resource recovery
Tailings dewatering: Processing the tailings slurry after beneficiation significantly reduces the risk of leachate pollution in tailings ponds, and the moisture content of the filter cake can be controlled at 15% -20%.
Uranium ore leaching solution filtration: efficient recovery of solid particles from precious metal leaching solution, improving resource utilization efficiency.
3) Mine water treatment
Process mine water containing suspended solids, purify wastewater through coagulation and sedimentation processes, achieve reuse or meet discharge standards, and reduce environmental risks.
2. Technological advantages and innovation points
1) Efficient continuous operation
The vacuum negative pressure system provides strong suction, which increases dehydration efficiency by more than 30% compared to traditional equipment and supports continuous production around the clock.
Modular structural design (such as DU series) supports quick disassembly and assembly, adapting to harsh working conditions in mines.
2) Significant energy-saving and water-saving measures: Adopting high-pressure self-cleaning filter cloth technology, there is no need to rinse the filter belt with water, resulting in an average daily water saving of 60-70m ³ per machine.
Reduce drug consumption: optimize the matching of vacuum degree and filter belt speed, reduce flocculant dosage by more than 50% compared to belt filter press (only 1.2-2kg/ton dry mud).
3) Environmental adaptability
Sealed design reduces dust and avoids the diffusion of heavy metal dust; Centralized recovery and treatment of filtrate to reduce wastewater discharge pollution.
4) Intelligent control upgrade
Equipped with an automated correction system (dual airbag cylinder serpentine correction) and real-time vacuum monitoring, reducing manual intervention and lowering the failure rate by 40%.
