Factors to be considered in the selection of vacuum dryer

Factors to be considered in the selection of vacuum dryer

1. The filter belt is required to have the characteristics of high tensile strength, bending resistance, acid and alkali resistance, and temperature change resistance. At the same time, the specific properties of the sludge should be considered, and a suitable weaving texture should be selected to make the filter belt have good Air permeability and performance on sludge particles.

2. The deviation adjustment system of the roller pressing cylinder.

Usually done by pneumatic devices.

3. The tensioning system of the filter belt is generally controlled by the pneumatic system. The tension of the filter belt is generally controlled at 0.3-0.7MPa, and the common value is 0.5MPa.

4. Belt speed control.

Different types of sludge have different requirements on belt speed, that is, there is a belt speed control range for any specific sludge. Quality mud cake.
