Product presentation

The  sludge dryer dewater sludge after drying, the moisture content is greatly reduced, the volume is very small. In order to facilitate the use and further processing. After drying, the moisture content of the sludge can be reduced to about 20% by volume also decreased, easy to transport, use or final disposal. For sludge drying process easy to knot the unity block characteristics, drying machine uses a multi-channel internal helical structure, and change the structure of the dryer drum plate, using a combined lifting plate structure, increased activity grate style wing and self-cleaning device, various types of sludge can be dried and drying a variety of high viscosity materials.

Performance features


Working principle

Sludge dryer can be one-time 90% of the water content of dried material to finished product. For sludge drying process easy to knot the unity block characteristics, changing the structure of the general single-channel plate dryer, using a modular self-cleaning device, which greatly expanded the single-channel dryer range of applications, not only can each dried class sludge can also be used for drying various high-viscosity materials.


Sludge from the feeder through the chute into the dryer material guide plate as the cylinder rotates, the sludge is led to tilt lifting plate i.e. elevated to the center position of the cylinder, gradually floating down the formation of curtain material , high-temperature air to pass therethrough, so that the sludge preheating and evaporation of some water. When the sludge spilled when moving to an active grate bars style wing plate material but also with the preheated grate-type wing mixed together, the heat transfer to the material, so that part of the water evaporates. Meanwhile, the flap entrained material filed, floating down, repeatedly, materials and hot air convection and contact heat exchange. While buried in the material of the cleaning device, but also along the back side of the arc-shaped lifting plate fell, the lifting plate inner wall adhesion material sweeping down. When the cleaning device turned vertical line with the cylinder and later, in the back of the arc lifting plate drag, which is adhered to the outer wall of the lifting plate material sweeping down. As the cylinder is rotated continuously, part of the water evaporated, the sludge was further dried. Meanwhile, the cleaning device of the sludge group smashed the ball also played a role in enhancing the drying rate, and finally dried sludge into low moisture loose material from the discharge port.
