Industrial Spiral Classifier
HSX FG/FC Series heavy industrial spiral classifiers provide wet hydrodynamic particle size classification, washing, de-sliming, and dewatering for mineral ore slurries and aggregate sands. Featuring high-wear white cast iron spiral shoes, high-weir settlement pool designs, and automated lifting devices, the FG Series maintains high separation efficiency across closed-circuit grinding systems.

Precision Wet Hydrodynamic Sizing & Dewatering
Gentle, low-turbulence settling pool separates fine slurry overflow from coarse sand with high grading accuracy.
Replaceable High-Chromium Alloy Spiral Shoes
Flight outer edges are bolted with modular high-wear white cast iron (Cr26) or polyurethane shoes for quick changeout.
Motorized Spiral Lifting Mechanism
Integrated electric motorized winch lifts the lower spiral head out of the slurry bed during shutdown, preventing startup motor stalls.
Heavy Flanged Tubular Center Shaft
Seamless heavy-walled seamless steel tube shaft with precision machined flange joints eliminates axial deflection under heavy sand bed load.
Fully Submerged Bottom Bearing Sealing
Multi-stage grease-purged labyrinth seal and rubber packing ring protect bottom pivot bearings against abrasive water ingress.
Proven in Severe Plant Environments
Delivering high thrust and zero-drift actuation across critical heavy industrial facilities.
Ball Mill Closed-Circuit Grinding
Returning oversized sands back to ball mill feed trunnions while discharging fine product overflow to flotation.
Sand Washing & Desliming Plants
Removing silt and clay impurities from crushed manufactured sand and silica aggregate.
Glass Raw Material Silica Purification
Dewatering and de-sliming high-purity quartz slurry prior to drying and screening.
Coal Slurry Classification
Separating coarse refuse from coal slurry in coal preparation froth flotation feed loops.
