1, It can change operation parameters according to different material property, the rotary drum dryer can form full section material fall which makes the heat exchange more fully;
2, New type feeding and discharging devices completely eradicate the disadvantages of traditional dryer like feeding jams, feeding discontinuously and unevenly, returning materials, and reduce the load of dust removal system ;
3, Scale plate sealing is used to connect shell and feeding and discharging device , good sealing greatly reduce the shell internal heat loss, thus directly reducing the fuel consumption;
4, Counter-current drying method obtains higher evaporation intensity; Fair current drying method and indirect drying way are suitable for drying temperature sensitive material;
5, New burner satisfies the customers’ demand for saving energy and high efficiency. It can choose diesel oil, heavy oil, natural gas, coal gas etc. to be fuel instead of the only choice for coal as fuel in the past.
Product Working Principle
The rotary dryer is mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. The dried wet material is sent to the hopper by a belt conveyor or a bucket elevator, and then fed through the hopper through the feeding pipe into the feed end. The slope of the feeding pipe is greater than the natural inclination of the material so that the material flows smoothly into the dryer. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the lower end, and is in countercurrent contact with the material, and the heat carrier and the material are simultaneously flowed into the cylinder. As the rotating material of the cylinder is moved by gravity to the lower end. During the forward movement of the wet material in the cylinder body, the heat supply of the heat carrier is directly or indirectly obtained, so that the wet material is dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor.
