Rotary Dryer

Rotary Dryer Introduction:
(Drying Machine) is used for drying materials with a certain humidity or granularity in milling

of ores, building materials, metallurgy and chemical industry. Rotary drying machinery has a

strong adaptability of materials and it can dry various materials. The operation is very simple

and liable. For this reason, it is used widely.

Rotary DryerComponents:
Rotary drier is mainly composed of cylinder, under frame, feeding and discharging devices,

transmission device, gear cover, etc. (Optional auxiliary equipment includes combustion chamber

feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us

adopts new lifting plate, which is of functions like guiding, currentsharing, and material raising.

The materials are raised and evenly drop so that they are in fullcontact with heat for better drying

efficiency. Our rotary drier is designed with the best working conditions, which enables it to save

10-15% of energy and increase 10-15% of productivity compared with common dryers.

Rotary Dryer Working Principle:
Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.The barrel is

installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air

enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower

side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and

down to make materials and hot air mix completely. So drying efficiency is improved.
