Equipment View

Applications

Sea salt, mineral salt and similar crystals
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

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

Get a Tailored Configuration

Provide feed properties, target purity, desired moisture and utility limits. We will map HR400-N / HR500-N / HR630-N to your capacity and washing needs.
