Rotary Electroplating Sludge Vacuum Hollow Paddle Dryer Customized

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

11) Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect.A large heat transfer area to volume ratio is achieved by the use of hollow discs and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.

12) The KJG series Paddle Dryer transports material, regardless of its handling characteristics. Sticky, pasty materials can be transported. Pre-conditioning the feed by mixing with recycled dried product, to make it conveyable, is not required. This results in lower capital, operating, and maintenance cost.

 

 

The main structure is a W-shaped shell with a jacket, which is equipped with a pair of hollow low-speed rotating hollow shafts. A number of mixing blades are welded on the shaft. The jacket and the hollow mixing blades are all equipped with heat carriers, and the two heating surfaces heat the materials at the same time. The heat carrier is usually fed from the middle of the dryer and discharged from the other side through the surface of the material layer in the agitated state.
Wedge-shaped hollow blades are densely arranged on the hollow shaft, and the thermal medium flows through the blades through the hollow shaft. The unit effective volume has a large heat transfer area. The temperature of the thermal medium ranges from - 40 ° C to 320 ° C, which can be water vapor or liquid type: such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to take away heat. Heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation layer of the reactor body. The heat transfer surface of the wedge-shaped blade has the function of self-cleaning. The relative movement of the material particles and the wedge-shaped surface can wash off the attached materials on the wedge-shaped surface, so that the clean heat transfer surface is kept in motion all the time.
