Sludge drying equipment is a drying equipment that dries various types of activated organic sludge and then manufactures sludge bio-organic fertilizer. The drying treatment of sludge makes it possible to treat the sludge for agricultural use, use as fuel, incineration and even to reduce landfill sites.

The sludge enters the guide plate in the dryer from the feeder through the chute. With the rotation of the cylinder, the sludge is guided to the inclined lifting plate, which is lifted to the middle of the cylinder, and gradually falls to form a material curtain. , the high temperature airflow passes through it, preheating the sludge and evaporating part of the water. When the sludge is spilled and moved to the movable grate-shaped wing, the material is mixed with the preheated grate-shaped wing, which transfers heat to the material and evaporates part of the water. At the same time, the material entrained by the wing plate is lifted and sprinkled, repeated many times, and the material and the hot air flow convection and contact heat exchange. At the same time, the cleaning device buried in the material also slides down the inner side of the arc-shaped lifting plate to clean the material adhering to the inner wall of the lifting plate. After the cleaning device rotates along the vertical line with the cylinder, it is dragged on the back of the arc lifting plate to clean the material adhering to the outer wall of the lifting plate. With the continuous rotation of the cylinder, part of the water is evaporated, and the sludge is further dried. At the same time, the cleaning device also plays a role in breaking up the sludge pellets, which improves the drying speed. After the sludge is dried, it becomes a loose material with low moisture, which will be discharged from the discharge port.
