Slag dryer is widely used in building materials, metallurgy, mineral processing, chemical, cement and other industries, can be used for drying slag, carbide, limestone, clay, sand, quartz sand, slag slurry, sludge and other wet large proportion large materials.
Slag drying production line is mainly composed of rotating the cylinder, the wind, high-speed dispersed equipment, lifting plate, since the cleaning device, gear, transportation equipment, hot air equipment, gear, support equipment, and seals and other components.
What are its advantages?
1. Handle than the larger, anti-overload ability, high thermal efficiency, reduce coal consumption about 20%, and directly reduce drying costs. Transmission size of the column can change gear using the gear off, replacing the traditional steel gears, investment cost, but also greatly reduces maintenance costs and time.
2. In the design to achieve the best drying results, using the downstream drying, the material from the same side with the heat flow into equipment, outlet temperature and low thermal efficiency.
3. The internal structure to achieve innovative, enhanced cleaning materials that have been scattered and thermal conduction, to eliminate the phenomenon of cylinder wall adhesions.
4. Using a new type of feeding, nesting devices to prevent it feed plug, not continuous, uniform and returning materials and so on, as you reduce the dust load of the system. The device on the system in the lifting device made many technological innovations, especially with a new multi-modular lifting device to overcome the traditional dryer’s “wind tunnel” phenomenon.
5. To meet the different users of slag material after drying class size and moisture requirements.
Its Work Principle:
1. The slag from the or bucket elevator to the hopper, then through the hopper of the feeder by feeding into the feed end of the pipeline.
2. The slope of the pipeline feeding the material to be greater than the natural inclination to mine the material smoothly into the drying machine.
3. A dryer cylinder is tilted slightly into the horizontal rotating cylinder. Material from the higher end of the join, body heat from the low-end entry into countercurrent contact with the material, but also heat carrier and the material together and flow into the cylinder.
4. Rotation of materials with the cylinder runs by gravity to a more bottom end. Wet material in the cylinder body moves forward in the process, and is directly or indirectly transported to the heat carrier of the wet material to dry, then the discharge end sent by or screw conveyor.
5. The cylinder wall with the body copy board is to copy the material up and planted, so that the contact surface of the material and increases airflow to improve the drying rate and to promote material progress.
6. The heat carrier through the dryer after the cyclone will generally require gas capture within the material brought down (heat carrier is generally divided into hot air, flue gas, etc.).
