Coal Washing Slurry Pump

The coal washing slurry pump is a wear-resistant centrifugal pump specifically designed for coal washing and selection processes. Its core function is to transport highly abrasive slurries with high solid content, such as coal slurry, gangue, and heavy media, preventing blockages and ensuring continuous production

Introduction

Characteristics

Essence: A variant of heavy-duty centrifugal pump that utilizes centrifugal force generated by impeller rotation to transport solid-liquid mixed media (coal slurry, coal water slurry, heavy medium suspension, etc.).
Key features: The overcurrent components (impeller, guard plate, pump casing) are made of high chromium alloy, wear-resistant rubber or ceramic materials, and the flow channel is wide to prevent blockage, designed specifically to cope with coal particle wear and high concentration working conditions.
Difference: Unlike ordinary water pumps, it does not pursue high hydraulic efficiency, but focuses on resistance to abrasion, impact, and the ability to pass large particles, with a significantly longer lifespan under harsh working conditions. ‌‌
Main application scenarios in coal washing process
Raw coal pretreatment: Transport coal slurry water after washing and removing impurities, containing fine coal particles, sediment, and small stones, which need to be anti blocking and wear-resistant.
Heavy medium sorting: Circulating transportation of heavy medium suspensions such as magnetite powder requires stable flow rate to maintain sorting density accuracy.
Tailings and coal slurry transportation: Transporting flotation tailings and concentrate tank bottom flow to tailings pond or filter press often requires a high head to overcome distance and sedimentation risks.
Clean coal dewatering process: Feed the filter press or centrifuge with stable operation to avoid flow pulsation affecting the dewatering effect. ‌‌
