Super Rotary Sludge Dryer
The Super rotary sludge dryer is a developed equipment by Jiangsu Benenv Environmental Technologies Co., Ltd. It incorporates the efforts of experts in the field of drying and carbonization from Japan, and universities professors. This equipment uses clean energy as heating and adopts direct drying method. The moisture content of the material can be reduced to 10%.
Compared with direct sludge heating and drying, the super rotary sludge dryer requires less energy and reduces carbon emissions, which meets the international low-carbon environmental protection requirements.
* Drying Principle
The sludge cake is pre-crushed by the stirring device of the feeding hopper, then conveyed by the twin-screw feeder to the main rotating drum, where the sludge will be crushed into small pieces of size 1-3 mm. The wall plates of the drum drives the small sludge particles forward, by lifting and dropping it, while being continuously stirred and crushed by the disintegrating shaft. The specific surface area of the material increases the contact area with the hot air and accelerates the drying process with high efficiency.
* Based on evaporation of 1 ton of water
