Working Principle
The machine operates according to the principle of centrifugal filtration separation.
Process Flow:
- Slurry enters the rotating basket.
- Centrifugal force drives liquid through the filter media.
- Solids remain on the basket wall forming a filter cake.
- Optional washing liquid cleans the cake surface.
- Centrifugal drying removes residual liquid.
- The scraper mechanism automatically discharges solids.
The process enables efficient solid liquid separation and crystal dewatering.
Process Description
Feeding Stage
Material slurry is automatically introduced into the centrifuge basket.
Separation Stage

Cake Washing Stage
Optional washing improves product purity.
Suitable for:
- Pharmaceutical crystals
- Chemical salts
- Food ingredients
- Fine chemical powders
Drying Stage
Residual mother liquor is removed by centrifugal drying.
Automatic Discharge Stage
The scraper blade removes solid cake automatically.
