Overview of sludge dryer

The sludge dryer produced by red star machine can dry the sludge, which is convenient for the production of sludge bio organic fertilizer. It is the drying equipment of organic fertilizer manufacturing enterprises. The drying treatment of sludge makes it possible for sludge to be used for agriculture, as fuel, for incineration and even for reducing landfill sites.

Sludge has high humidity, and high adhesion, during the drying process, wet slime are sent into scattered equipment via ribbon conveyor, The massive sludge after scattering are sent into drying chamber dryer of negative pressure to be dried.

The sludge dryer can be widely used in the drying of activated sludge, sewage sludge, petrochemical sludge, papermaking sludge, printing and dyeing sludge, tanning sludge, electroplating sludge, municipal sludge, biological fermentation sludge, etc.

Sludge dryer is mainly used to dry slime, raw coal, peat, flotation concentrate, mixed coal, tailings and other materials in coal industry.

Working principle of sludge dryer

The sludge enters the guide plate in the sludge dryer through the chute of the feeder. With the rotation of the cylinder, the sludge is led to the inclined lifting plate, that is, it is lifted to the central position of the cylinder, and gradually spreads to form a material curtain, through which the high-temperature air flow passes to preheat the sludge and evaporate part of the moisture. When the sludge spills and moves to the active grate wing plate, the material is mixed with the preheated grate wing plate to transfer heat to the material and make part of the water evaporate. At the same time, the material carried by the wing plate is lifted and scattered, repeated for many times, and the material and hot air flow carry out convection and contact heat exchange. At the same time, the cleaning device buried in the material also slides along the inner side of the arc-shaped lifting plate to clean the materials adhered to the inner wall of the lifting plate. When the cleaning device turns the vertical line with the cylinder body, it drags on the back of the arc lifting plate to clean the materials adhered to the outer wall of the lifting plate. With the continuous rotation of the cylinder of the sludge dryer, 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 the sludge balls and improving the drying speed. After drying, the sludge becomes loose material with low moisture content and is discharged from the outlet of the sludge dryer.

Performance characteristics of sludge dryer

1. The sludge dryer has strong overload resistance, large capacity, less fuel consumption and drying;

2. The new feeding and discharging device reduces the load of dust removal system by blocking, discontinuous, uneven and returning materials;

3. Adopting the forward flow drying method has high thermal efficiency;

4. According to the user's requirements, the product particle size and moisture can be controlled. The moisture content of coal slime drying product can be less than 8%, and the particle size can be controlled below 8 mm;

5. The sludge dryer adopts the "center adjustment type supporting wheel device", which makes the coordination of the supporting wheel and the rolling ring always in linear contact, thus greatly reducing the wear and power loss;

6. The "zero horizontal thrust" of the dryer greatly reduces the wear of the supporting roller, and the cylinder runs stably and reliably.

 Sludge Dryer

1. Sludge dryer has strong anti-overload capability, large quantity management, low fuel consumption, low drying costs;

2. New feeding, discharging devices can prevent phenomenon of clogging of the feed drum dryer, not continuous, not uniform and returning materials, reduce the load of the exhaust system;

3. Adopt downstream drying, high thermal efficiency;

4. Control particle size and moisture according to user requirements, the moisture of sludge drying product reaches to below 8%, particle size can be controlled less than 8mm;

5. Sludge dryer adopts self-aligning roller device, so the roller and rolling ring are linear touched, thus it greatly reduce the wear and power loss;

6. Sludge dryer achieves a “zero thrust” which greatly reduces the wear of roller block, to make sure the smooth and reliable operation of cylinder.
