As people's awareness of protecting and improving the living environment has been strengthened, and the national environmental protection policy has been continuously strengthened, the national sewage treatment rate has continued to increase. All cities have sewage treatment plants, but they all face the problem of how to deal with the large amount of surplus sludge generated every day.

　　Sludge is industrial waste produced in the production process of urban sewage treatment. Because sludge has many shortcomings (such as high water content, high viscosity, large water holding capacity, low heating value, etc.), sludge drying equipment has been developed.

　　Two main advantages of sludge drying equipment:

　　1. Energy saving and consumption reduction to ensure low-cost operation of equipment

　　2. The working environment is clean and hygienic, with good environmental performance
