Industrial Sludge Hollow Paddle Dryer Dehydrator Kaolin Clay Slurry Drying Machine

Hollow Paddle Dryer

KJG series double shaft sludge paddle dryer are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. They are used for drying, heating or cooling paste, filter cake, powder and small granule materials in almost all kinds of industrials. Sludge drying is one of its most successful applications.Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing and optimize heat transfer. The use of hollow discs and drying chamber heating jacket for heat transfer results in a compact machine. The heat transfer medium: steam, hot water or hot oil is isolated from the process mass. The KJG series Double Shaft sludge Paddle Dryer provides a reliable and efficient method for drying slurry, filter cakes and centrifuge concentrates. The exhaust gases can be treated by cyclone, condenser and scrubber to considerably reduce air contamination. For those wet materials of heat sensitive, easy oxidized, containing organic solvents which need to be recovered, vacuum design is available.

Working principle:

Hollow shaft dense arrangement with the wedge-shaped hollow blade, the heat medium through the hollow shaft flow through the blade. The effective volume of heat transfer area is very large, the heat medium can be water vapor, can also be hot water or heat conducting oil. The heat transfer medium flows through the shell jacket and the hollow stirring shaft through the rotating joint, and the hollow stirring shaft has a different internal structure according to the type of the heat medium to ensure the best heat transfer effect.
In the pulp and jacket access to hot oil, heating at the same time, the upper part of the discharge port at the same time through the heated dry air after further drying, thus greatly increasing the drying strength of the device. Evaporated moisture from the tail gas out of the dryer, wet air discharged by the induced draft fan outdoors.

Features
1. High thermal efficiency which can reach 95%
2. Heat transfer medium does not contact the product.
3. Gas is not used to convey the product. Off-gas flow is minimal.
4. Precise control of temperature
5. Uniform product quality, through mixing and movement of the product
6. Continuous process on a once-through basis
7. High heat transfer area to process volume ratio - reduced floor space
8. Easy to operate, requires minimal attention
9. Safer than direct drying when processing combustible material
10. Simple durable design for easy and low maintenance

FAQ
Questions: What information should be provided in order to get a proposal or quotation?
Answer: Each paddle dryer is specially designed for each customer according to specific wet materials, capacity, drying temperature and heat mediums. Before we can work out a detailed proposal or quotation, we have to know the following information:
1) Detailed information of wet material are you going to dry. We may ask you to provide composition report or samples to do drying test.
2) Initial moisture content before drying
3) water content of dried product
4) Handing capacity per hour
5) Heat medium to be used for drying. Such as steam, thermal oil or hot water
Questions: How the machine will be delivered ?
Answer: Paddle dryer is very heavy and its weight ranges from 3 tons to 50 tons. When the heating area is less than 60 M2, the dryer body can be shipped by 40 feet HQ container; 60-100 M2 can be shipped by 40 feet OT container; more than 100 M2, the dryer body should be dismantled for shipping.
