rotary dryer

Description of the Rotary Dryer:
This rotary dryer, also known as drum dryer, is a kind of fertilizer unit mainly used for drying materials in cement sector, mineral industry, building material field, chemical industry, food industry, and fertilizer industry, etc. And this dryer can be used independently as well as in combination with other fertilizer equipments.
Its main components are rotary body, lifting blade, driving device, supporting device and sealing ring.

Features of the Rotary Dryer:
1.This rotary dryer is mainly characterized by rational structure, high efficiency, low energy consumption, reliable performance, and easy operation, etc.

2.This machine has a lower consumption degree of coal and electricity. Besides, it possesses a production capacity ****5% higher than common ones.
3.In order to better control the temperature of the dryer, the feeding device and discharging device are fitted with thermocouples. Thus, temperature changes of the feeding end and discharging end of this rotary dyer can be clearly showed by thermocouples. In this way, users can better control the working temperature inside rotary dryer at ******0℃.

Working Principle of the Rotary Dryer:
1.The heat source of this rotary dryer is from combustion apparatus, and this rotary dryer adopts counter flow type heating mode.
2.The heating air supply enters into the dryer through discharge end, and materials to be dried enter into the slant rotary dryer through feed box. When materials to be dried enter into the dryer, they will be pushed to the back of the drum by spiral shoveling plate. 
3.On one hand, materials flow to the back under functions of gravity and rotary force. On the other hand, they are shoveled up repeatedly by the shoveling plate, and those materials are sent to the upper end and then fall down. In this way, those materials take the shape of curtains, so they can easily and fully exchange heat with hot air.  Gradually those materials can be thoroughly dried.
