Operating principle
Rotary dryer is the most common and wide drying equipment in mining machine, and its cylinder is the horizontal rotating cylinder barre. Rotary dryer is suitable for drying of metallic and non-metallic mineral magnetism’s magnetic, heavy, floating concentrate, cement industry’s clay and coal industry’s slime. It’s characterized by high productivity, easy operation, etc.
Operating principle
The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
Advantages1 Adopted new combined-type feed and feed device, the center of second material without wind.
2 Cleaning, maintenance is convenient.
3 High heat efficiency.
4 Phenomenon of drying.
5 Reliable performance.
6 Transmission large and small gear pin can change gear, replaced the traditional gear of cast steel, saving the cost of investment, and also greatly reduces maintenance costs and time.
