Slag dryer, also known as granulating slag dryer,steel slag dryer,gold ores dryer and lead powder dryer, is mainly made up by rotary cylinder, wind equipment, transmission equipment, hot air equipment, deceleration machine, supporting devices, high-speed scattered equipment, feed plate, the cleaning device, transmission device, sealing device, etc. The slag dryer has advantages of reasonable design, perfect workmanship, stable performance, advanced technology, high output, low energy consumption, high mechanization degree, etc.
Slag, limestone, clay, sand, quartz sand, slime, sludge and other materials with high moisture content can be dried by slag dryer.
1. Slag dryer can handle a large quantify and has strong anti- overload capability, high thermal efficiency and low drying cost.
2. Fluorite ore dryer adopts downstream drying method, the material and heat flow get into the drying machine from the same side. The temperature of the dryer exit is low, and it has high heat efficiency.
3. Gold ores dryer uses a new combined feed device which overcomes the “wind tunnel” phenomenon of the traditional dryer.
4. Lead powder dryer can satisfy the size and moisture requirements of different customers after the drying of slag materials.
The slag is sent into the hopper by the belt conveyor or bucket elevator and sent into feed end through feeding pipe of feeder hopper. The dryer cylinder is a rotating cylinder with slight incline to the horizontal line. The materials are sent from the higher end and the heat-carrying agents are sent from the lower end to be countercurrent contact with the materials. Some heat-carrying agents and materials flow altogether into the end of the barrel with the gravity effect as the rotation of the cylinder. In the process of moving forwardness in the barrel, the wet materials are directly or indirectly gained the heat of the heat-carrying agent and be dried, then the discharge end discharges finished products through belt conveyor or screw conveyor.
