Hot Sale High Efficiency Hollow Paddle Dryer for Electroplating sewage sludge

The material overview:

Electroplating sludge is the electroplating industry wastewater treatment of the "final thing", which contains a lot of copper, nickel, chromium, iron, zinc and other precious metals.

Electroplating sludge mainly from the industrial electroplating process of various electroplating waste and electrolytic bath liquid through the liquid chemical treatment of solid waste, due to the electroplating manufacturers of different production processes and treatment processes, electroplating sludge chemical composition of considerable Complex, mainly containing chromium, iron, nickel, copper, zinc and other heavy metal compounds and soluble salts.

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.
