Product Application

Rotary drying equipment is widely used for drying materials with humidity or granularity in the industry of mineral powder, building materials, metallurgy, chemical and so on. Such as sand, coal, sludge, coal slurry, brown coal, fly ash, gypsum, clay, kaolin, grain(corn, wheat), slag, iron powder, mill scale, sawdust, chicken manure, feed etc. 

Components

Rotary drying equipment mainly consists of a large revolving cylindrical tube, wheel gear, roll ring, supporting device and reduction gears etc. In the feeding terminal, we adopt screw feeding device to make materials enter into tube successfully. There are many lifting boards which fixed on the inner wall of tube. This device greatly increase the connection surface with hot air and improve the drying efficiency. On the traditional technical, our company specially subject a number of steel chains ans movable plate, which resolve the problems of sticky materials with easy block. Other related equipments are conveyor, dust remover and draught fan etc. 

Working Principle

Wet materials are sent into hopper by belt conveyor or bucket elevator, then enter into the tube. The tube has slope slightly so that the discharge end is lower. During drying process, materials are lifting up repeatedly by lifting boards and contact with hot air sufficiently. Then the moisture contained in materialsis vaporized. At the end of, the waste gas is released into atmosphere by draft fan .
