Rotary drum dryer can dry many different raw materials contain moisture, such as sawdust, coal, coal slurry, slag, fertilizer, sand, chicken manure, cassawa and sugar bagasse, etc. They are widely used in building materials, metallurgy, and chemical industry.
Rotary dryer structure
Rotary drum dryer cosists of rotary body, lifting blade, driving device, supporting device, sealing ring.
Heating source can be coal, charcoal, wood, gas, electricity, oil, wind power, etc.
Working principle: Wet materials are sent to dryer by conveyor belt or elevator, or in order to feed materials continuously and smoothly, you can add a feeder. When installation, the drum need have a 3-5º inclination, to ensure the materials move from the upper part to lower part smoothly. In upper part, we can build up a brick heating stove or coal-gas producer, make the hot air enter into dryer, and materials and hot airs are contacted completely, due to constantly raised and shed materials, then wet materials are dried.
