Principle

Materials are send to hopper of rotary dryer by belt conveyor or bucket elevator, the hot air move forward from the tail, then full access with materials,through heat conduction,convection and radiation heat transfer,then deliver the heat to materials directly,then the materials moisture content is evaporated constantly in the cylinder body,the wind device on the outlet take out a large number of moisture,wet,to prevent the second pollution caused by the dust discharging.Through the spiral stirring and shovelling plate to drive the material moved,until finish the whole drying proces
The raw materials are send to hopper by belt conveyor or bucket elevator firstly, and are send into feeding end by hopper feeder and feeding pipe. The feeding pipe slope is bigger enough to keep sure that the materials can be sent into dryer smoothly. The dryer cylinder is a rotary one which has some angels with horizonal line. Materials are fed into dryer from one end with heating-carrying agent, and pass through inner cylinder, middle cylinder and outer cylinder to output end and then to final product hopper. The dust carried by heat-carrying agent normally need to be collected by cyclone. To further reduce the dust content, it needs bag filter or wet dust collector. The dried products are sieved to get qualified size as final products.

Advantages：Inquiry > >

1.Our dryer adopt reasonable parameters, consumption of coal and electricity will be 10-15% lower than common dryers. 2.Rotary dryer is used widely in various industries, and the color and shape of final product is very good. When the dryer is working, it keeps smooth and can dry material very fast, which obtains higher revenue.
3.Little malfunction, low maintenance cost and power consumption.
4.intelligent control The rotary dryer can control the temperature of barrel, and we can install thermometer at the feeding part, so that we can control the temperature of materials.
