Hot sale Continuous vacuum rotary hollow paddle sludge dryer for sludge

Dual counter-rotating shafts with unique intermeshing hollow wedge-shaped paddles produce intimate mixing, optimize heat transfer, and provide a self-cleaning feature. A large heat transfer area to volume ratio is achieved by the use of hollow paddles and a jacketed vessel, through which the heating medium flows. The result is an efficient, compact machine with less space requirements and lower installation cost.

WORKING PRINCIPLE

KJG Series New Type Hollow Paddle Dryer for Industrial Sludge is a kind of conduction heating and low rotating speed-stirring type drier. There is jacket on the body of drier, hollow oar blade on the hollow shaft, filling heating medium in them, wet material is stirred by oar blade and carries on heat exchange with shaft and oar blade. The structure of the machine is generally horizontal type with two or four shafts.

1. Blanking dryer low energy consumption: due to indirect heating, there is no large amount of heat taken away with the air, the dryer wall is installed the insulation layer, save more energy than the usual convection drying method.

2. Hollow paddle dryer system cost is low: the unit effective volume has a huge heat transfer surface, to shorten the processing time, equipment size becomes smaller, it greatly reduces the building area and building space.

3. A wide variety of process problems can be solved by using any kinds of heating source. It is especially suitable for drying heat sensitive materials and light temperature materials. The normal heat transfer medium can be steam, heat transfer oil, hot water, as well as cooling water etc... The dryer can be used for continuous or batch processing. It has been widely used in many industry areas already.

4. Small environmental pollution: do not use air with dust material. Material solvent evaporation is very small, easy to handle. For the pollution of the material or the need to recover the solvent conditions, can be used the closed circuit.

5. Low operating costs: normal operation of the device, only 1 hour/day. Low-speed mixing and reasonable structure. Wear rate is very low, and maintenance costs are also very low.

6. Stable operating continuously: Because of the special compression and inflation of the agitation function of paddle dryer, the material grains touch the heat-transfer area thoroughly. Within the axis direction, the temperature, moisture, mixture, and grades of the materials is very small so as to guarantee the stability of the whole process.
