Tailings Pump
Agitation mechanism prevents settling and clogging
Tight sealing, suitable for high-concentration slurries
The tailings pump is a core piece of equipment in mineral processing plants used to transport high-concentration, highly abrasive tailings slurry. Its flow-path components are made of high-chrome alloy, effectively resisting the high-speed erosion caused by tailings particles. An agitation device at the pump base stirs up settled tailings for direct extraction, preventing clogging. The unit operates fully submerged, eliminating suction lift limitations and simplifying installation. With a flow rate range of 10–2000 m³/h and a head of 5–120 m, it meets various transport distance requirements and is widely used in tailings discharge, tailings pond reclamation, and sedimentation tank desilting. Miaoshun Pump Industry offers tailored solutions based on slurry concentration, particle characteristics, and site conditions.
Product Features
High-chrome flow-path components
The impeller and casing liner are made of high-chrome wear-resistant alloy, offering high hardness and impact resistance to effectively withstand high-speed erosion from tailings particles.
Double-layer casing design
The outer casing bears the pressure while the inner liner provides wear resistance; the liner can be replaced independently, significantly reducing maintenance costs and downtime.
Bottom anti-settling agitation
Equipped with a coaxial agitation impeller that directly stirs up and draws in settled, compacted tailings, eliminating the need for additional water-jetting equipment.
Multiple leak-proof seals
Uses a combination sealing system to prevent slurry leakage, coupled with motor water-ingress protection, ensuring continuous and safe equipment operation.
High piping adaptability
The discharge outlet supports 45° multi-angle rotation for flexible alignment with on-site piping and allows for multi-stage series connection to increase total head.
Wide range of applications
Covers flow rates of 10–2000 m³/h and heads of 5–120 m, with a maximum submersion depth of 50 m, meeting diverse requirements for tailings discharge and desilting.
Applications
Mineral processing plants: Long-distance tailings discharge, ball mill and cyclone feed, and concentrate slurry transport.
Underground mine backfilling: High-pressure injection of paste-produced by mixing tailings with cementing agents-into mined-out areas.
Coal preparation plants: Transport of coal slime water and dense-medium suspensions, as well as feed for tailings filter presses.
Coal-fired power plants: Hydraulic removal of boiler slag and fly ash.
Sand, gravel, and environmental projects: River sand dredging and desilting, hydrometallurgy, and transport of flue-gas desulfurization (FGD) gypsum slurry.
FAQ
Q: What is the difference between a tailings pump and a standard slurry pump?
A: A tailings pump is essentially a slurry pump reinforced to handle extremely harsh operating conditions. Unlike standard slurries, tailings are characterized by high hardness and extreme abrasiveness; therefore, tailings pumps utilize flow-path components made of ultra-hard alloys or tough, resilient rubber. They are also equipped with high-pressure, leak-proof shaft sealing systems to ensure reliable operation-without pump jamming or slurry leakage-during high-pressure, long-distance transport.
Q: What is the service life of the tailings pump's flow-path components?
A: Service life depends primarily on the tailings' quartz content, particle size, and operating concentration. Under standard conditions, high-chrome alloy or rubber components typically last between 3,000 and 8,000 hours; however, if the ore is hard and the particles are coarse, this lifespan may be reduced to 1,000–2,000 hours. It is recommended to implement a routine ultrasonic wall-thickness monitoring program and replace components when wear reaches 60%–70% of the original thickness to prevent casing breach and subsequent production downtime.
