Description
The rotary dryer, as a material heating and drying device, realizes drying process by making materials inside the coaxial rotary drum move back and forth between the inner and external wall driven by the spiral vane and interrupted spiral raising plate.
Rotary dryers or kiln dryers are mainly used to dry slag, clay and coal powder in the construction and metallurgy industries, and leaching residue of the metal processing industry. Rotary dryer is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350o)
Features
1. The rotary drying machine or rotary dryer is with high mechanization, strong production capability and continuous operation 2. Excellent and simple structure, steady operating process under resistance of the drum, easy operation 3. Little malfunction, low maintenance cost and power consumption 4. Wide application range and good drying effect.
