Working Principle
The horizontal screw centrifuge relies on the density difference between the solid and liquid phases to accelerate the sedimentation rate of solid particles under the action of centrifugal force to achieve solid liquid separation. The centrifuge consists of two rotors, one called a drum, and the other rotor is a screw discharger (referred to as a screw). When the drum rotates at a high speed, the slurry inside the drum rotates with the drum and is subjected to a centrifugal force that is many times greater than gravity. In this way, solid particles will be separated from the liquid and settle onto the inner wall of the drum from the centrifuge drum shaft. The screw discharger located inside the drum rotates at a speed lower than the drum and pushes the deposited solid particles to the slag outlet, The differential rotational speed between the outer drum and the screw discharger depends on the transmission ratio of the differential and its rotational speed..

Characteristics of suspension materials
1. The larger the solid particles, the easier the separation.
2. The machine can remove particles above 5um.
3. Small particles will not settle and will be discharged with the clarified liquid.
4. Separation effect depends on the distribution of solid particles.
5. Crystalline solids and fibrous solids are easier to separate.
6. Flocs and paste solids are more difficult to separate due to their large maximum water solubility.
7. Greater weight difference between solid and liquid phases results in better separation.
8. Lower liquid viscosity leads to easier separation.
9. Feed flow rate affects separation efficiency.
10. Smaller feed flow rate results in better separation.
11. Larger feed flow rate decreases retention and reduces separation effect.
12. Appropriate feed rate should be selected based on material characteristics, separation requirements, and solid content.
13. Recommended flow rate should not be too large for materials that are difficult to separate.
14. Maximum slag discharge amount of spiral should be considered to avoid material blockage.
