Factors Affecting the Dryness of the Sludge Out of the volute dewatering screw press

Properties of sludge:
When other parameters are fixed, the sludge dryness of different industries will be different after dehydration. For example, the sludge dryness of the paper industry is dry, but the sludge dryness of the petroleum industry is wet.

Spindle speed:
In some sites, in order to increase the amount of mud output, the spindle speed is increased, which will also cause the filtrate to be discharged before it is completely filtered out, resulting in non-dry mud output.

Filtration length of stacked screw filter body:
In order to save costs, some snail dewatering machine manufacturers shorten the filter body of the snail stacker. If the filter body is too short, the filtrate will be discharged before it is completely filtered out, resulting in non-drying of the mud.

Back pressure plate back pressure gap:
If the gap is too large, there will be no extrusion force on the sludge, and the sludge will not dry out. The smaller the back pressure gap, the greater the extrusion force, and the greater the dryness of the sludge. However, if the back pressure gap is too small, the sludge will not be able to Expelled, causing the shaft to hold.
