The Horizontal sludge dewatering machine is a widely used sewage treatment equipment. The moisture content of the sludge treated by this equipment is generally about 80%. What are the factors that affect the dryness of the sludge from the sludge dewatering machine?

  1. The nature of sludge

After the sludge dewatering in different industries, the dryness of the sludge will be different. For example, the dryness of the sludge in the paper industry is dry, and the dryness of the sludge in the oil industry is wet. Sludge in different industries determines the difference in dryness.

  1. Spindle speed

In some sites, in order to increase the mud output, the spindle speed is increased, which will also cause the filtrate to be discharged without being filtered out, resulting in the mud not drying out.

  1. Back pressure clearance of back pressure plate

If the gap between the back pressure plate is larger, the sludge will be discharged without being fully squeezed, and the humidity will be higher. If the back pressure gap is smaller, the extrusion pressure is higher and the dryness is higher. However, the clearance of the back pressure plate has strict standards and should not be too large or too small.

  1. Sludge flocculation effect

The dosage of PAM will directly affect the flocculation effect of sludge. The dosage is small, the flocculation effect is poor, and the mud dryness is poor. The sludge discharged with excessive dosage is sticky and slippery, and the dryness of the sludge will also become worse. Appropriate dosage can ensure the dryness of the mud.

  1. The product quality is not good enough

Some manufacturers will shorten the size of the main body of the screw stacker because of cutting corners, resulting in the filtrate not being completely filtered out, resulting in poor mud production.
