Hanpu Pusher Centrifuge Solution for Salt (HR Series)
A continuous, double-stage pusher centrifuge for salt crystals — covering separation, washing and cake discharge at full speed. Verified specs and images for engineering use.
Solid–liquid separation with crystal size > 0.05 mm and slurry concentration ≥ 35%
Continuous operation with in-situ washing and low moisture cake
Control system options: PLC + inverter. Temperature allowed: below 105 °C.
Key Advantages
Continuous feeding, separating, washing and discharging at full speed
Moisture in cake: less than 4% (typical, by model and conditions)
Stable performance, large capacity and good washing effect
Typical price range per set: USD 25,000–90,000 (FOB Shanghai).

Notes: choose model by feed crystal size distribution, solids concentration, washing demand and utility limits.
Front Housing
Front housing with process nozzles.
Typical Process Flow
Crystallization → concentration
Pusher centrifuge: separation + washing
Cake moisture control → drying/packaging
Keep wash liquor and mother liquor on separate lines to prevent cross-contamination.
Recommended Operating Window
Crystal size > 0.05 mm
Slurry solids ≥ 35%
Process temperature below 105 °C
