Sludge Dryer

Applications

Various sludges and high-viscosity materials.

Product Introduction
To address the tendency of sludge to agglomerate during dewatering, we have modified the feed plate structure of conventional single-channel dryers and adopted a combined self-cleaning device. This significantly expands the application range of single-channel dryers, making them suitable for drying not only various types of sludge but also various high-viscosity materials.

Key Advantages
● Can process sludge with a moisture content of 90% and boasts strong adaptability.
● Equipped with a lifting plate within the drying drum, the material is evenly heated and thoroughly dried.
● The dryer boasts a high degree of automation, utilizing an advanced fuzzy control system for automatic control of product quality.
● The sludge dryer boasts a rational structure, superior workmanship, high output, low energy consumption, and easy operation.

Operating Principle
Sludge is fed from a feeder through a chute onto the guide plates within the sludge dryer. As the drum rotates, the sludge is directed onto the inclined lifting plates, where it is lifted to the center of the drum and gradually dispersed, forming a material curtain. High-temperature air flows through this curtain, preheating the sludge and evaporating some of its moisture. As the sludge falls and moves onto the movable grate wings, it mixes with the preheated grate wings, transferring heat to the material and evaporating some of its moisture. Simultaneously, the wings carry the material, lifting and dispersing it repeatedly, creating a continuous flow of heat through convection and contact with the hot air. Simultaneously, a cleaning device embedded in the material slides down the inside of the arc-shaped lifting plate, clearing any material adhering to the inner wall. After the cleaning device rotates with the cylinder past the vertical line, it drags along the back of the arc-shaped lifting plate, clearing any material adhering to the outer wall. The continuous rotation of the sludge dryer cylinder evaporates some of the moisture, further drying the sludge. The cleaning device also breaks up sludge clumps, accelerating drying speed. After drying, the sludge becomes a low-moisture, loose material that is discharged from the sludge dryer's outlet.
