First, the working principle
Wet material from the belt conveyor or bucket elevator into the hopper, then through quantitative feeder, feeding tube into the tank and dryer cylinder of the dryer cylinder is a slightly inclined to the horizontal rotating cylinder, the material from Join the higher end of the heat carrier and the material in parallel flow into the cylinder body (also countercurrent) with rotation of the cylinder and the cylinder wall copy board role, as well as materials affected by gravity, so that the material runs to the material estuary, wet material in the process of moving the cylinder body, the direct heat exchange with the heating medium cut, the wet material to dry.
Main characteristics
1, the product is dried uniformity.
2, a large number of consecutive dry materials, large capacity.
3, simple structure, easy to operate, durable, less failure, low operating cost, reliable operation.
4, operating flexibility, adaptability.
5, fluid resistance, and resistance at 10-15mmH2O, energy saving.
6, can use high-temperature heat, the highest temperature up to 400 ℃.
7, the precipitation rate of up to 80% to 12%, the output can handle wet residue having 1 to 20 t / h.
Third, the scope
Rotary drum dryer is widely used in chemical, pharmaceutical, light industry, coal, building materials, food and metallurgical industries of the particulate material, the material moisture range of 3-25% in the treated, dried and water content of 0.5% the following.
