Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials,metallurgy, and chemical industry. Rotary dryer is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube,the dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.
Working principle:
The rotary dryer uses the sleeve sets out the structure can be doubled to reduce the length of the dryer, due to significant reduction of the cooling surface, resulting in decreased heat consumption, while doubling the heat exchange surface to greatly enhance thermal efficiency. Materials that can not touch tobacco, multi-drum rotary dryer provided in the inside and outside the cylinder, respectively, within the smoke pipe and circular pipe, the flue pipe of communication between the radial, the same energy efficient. It is obvious that on the hot and cold media in terms of material, this machine a sleeve-type rotary cooler.
The rotary dryer is mainly composed by the revolving body, lifting plate, driving device, supporting device, sealing ring and other components.
--big processing capacity,
--simple maintenance,
--long service life,
--reasonable structure,
--high efficiency,
--low energy consumption.
