Analysis of the difference between belt type sludge dehydrator and stacked screw type sludge dehydrator. Even if it is the same separation material, different process methods and working conditions also have different separation characteristics. The characteristics of separated materials are just the key factors that affect the effect and processing capacity.

      The settling speed of the separator of the screw type sludge dehydrator mainly depends on the size and shape of the solid particles. Then, the settlement speed can be adjusted and improved by the following measures:

1. In order to improve the viscosity and the density difference between the liquid and the solid phase under the condition of adjusting the temperature;

2. Adding flocculant to increase the particle size and change the particle shape of solid particle agglomerate.

In addition to the above two methods, some materials that are difficult to handle can also be operated in the following ways:

1. Increased aspect ratio

2. Adjust the speed of the drum

3. Adjust the differential speed between the drum and the discharge screw

4. Cone section of the half cone angle of the changed drum

5. Adjust the overflow radius of liquid phase outlet

6. Change the number of discharge screws and screw heads and screw angle

7. Add BD board structure
