The company's production equipment is advanced and complete

The sludge dryer is an indirect heating low-speed stirring dryer. There are two or four hollow rotating shafts inside the equipment. On the hollow shafts, fan-faced wedge-shaped hollow blades are densely arranged in parallel, and the structure design is special and ingenious. The relative rotation of the shaft body uses the principle and structure of the same angular velocity but different linear velocities to ingeniously achieve the self-cleaning effect of the sludge on the shaft body, which prevents the "shaft holding" phenomenon in the sludge drying process to the greatest extent.
