KJG Series high efficiency hollow paddle dryer for sludge treatment

Product Description:

The KJG Series High Efficiency Hollow Paddle Dryer is a premier industrial solution specifically engineered for the challenging task of sludge dehydration and volume reduction. This low-speed agitation dryer utilizes indirect conduction heating, ensuring that wet sludge comes into full contact with the heat transfer surfaces to achieve a high-efficiency drying purpose without the need for large volumes of air.

Whether handling municipal sludge, petrochemical waste, or industrial slurry, the KJG series offers a robust, self-cleaning, and energy-saving system designed for continuous 24/7 operation.

Technical Specifications

• High Thermal Efficiency: The system uses indirect heating, meaning all heat is used to heat the material; only 1.2 kg of steam is needed to evaporate 1 kg of water from slurry.

• Self-Cleaning Technology: The wedge-shaped stirring blades feature a unique self-cleaning function that removes adhering material, maintaining a clean heat transfer surface for consistent performance.

• Stable Piston-Flow Processing: Sludge moves in a "piston flow" along the axial direction, ensuring uniform drying with minimal gradients in temperature and humidity.

• Low Environmental Impact: Since it does not use air for heating, dust entrainment is minimal, making it ideal for contaminated materials or systems requiring solvent recovery.

• Compact Footprint: The large heat transfer area per unit effective volume significantly reduces equipment size and building space requirements.

FAQ

Q: What heat media can be used with the KJG series?

A: The system is highly versatile and can use steam, thermal oil, or hot water, with temperatures ranging from -40°C to 320°C.

Q: How does the dryer handle sticky or pasty sludge?

A: The wedge-shaped blades create a special compression-expansion stirring effect that ensures sticky materials stay in contact with the heat surfaces and are continuously moved forward by the "piston flow".

Q: Is the maintenance cost high for such heavy-duty equipment?

A: No. The structure is designed to minimize wear and tear, and the self-cleaning mechanism prevents buildup, resulting in very low operating and maintenance costs.
