Drying of electrolytic anode sludge
Thread Content
In zinc electrowinning, how is the anode sludge taken out of the electrolyzer dried?
Just let it dry naturally; using a dryer would consume too much energy
The hollow-paddle dryer has low energy consumption, causes no dust pollution, and is easy to operate; it is used for anode sludge in Shandong

The structural design of the hollow-blade dryer is highly suitable for drying anode sludge that is sticky and contains a high amount of moisture. Its advantages are environmental friendliness and energy efficiency; this is how such materials are dried abroad
Anode sludge contains acid, making it very difficult to dry
Replying to the person on floor 6: It’s okay if there is acidity; using the appropriate type of steel will solve the problem, as long as it does not contain hydrofluoric acid
Hollow blades – Tianhua has many achievements in this area
The technology for drying anode sludge using hollow paddle dryers is not yet mature; it is particularly unsuitable for anode sludge with high viscosity and high water content. I have painful experience to prove this.
