Sludge drum dryer is a kind of equipment designed based on the principle of heat conduction, which is specially used for drying materials with high moisture content such as sludge.

The working principle of sludge drum dryer mainly relies on the heating effect of heat source on the material, so that the moisture inside the material evaporates, and the water vapor is discharged through the internal fan, so as to achieve the drying of the material. Specifically, the wet sludge is sent into the drum, and the drum continuously picks up and throws the sludge during the rotation process, so that the sludge is fully in contact with the hot air flow, thereby improving its drying efficiency. At the same time, the high temperature environment inside the drum promotes the rapid evaporation of the moisture in the sludge, and the water vapor is discharged by the fan.

Sludge drum dryer is widely used in urban sewage treatment, industrial wastewater treatment, agricultural waste treatment and other fields. It can dry materials with high moisture content such as sludge, medicinal residue, fruit residue, soy sauce residue, bagasse, peat, etc., which provides convenient conditions for subsequent storage, transportation and further utilization.
