The three-ring drum dryer realizes high-temperature and fast drying process, Compared with the traditional dryer, the floor space is reduced by 2/3, energy saving is 40%, and the drying strength is doubled.
The Sawdust and other materials enters the belt conveyor through the feeding hopper, and the equal-thickness stream is fed into the dryer feeding port through the feeding air-closing device, and enters the multi-cylinder roller together with the high-temperature hot flue gas from the hot air furnace at the feeding port of the dryer. after three cycles of mass heat exchange to complete the drying of the material, the dried material enters the multi-group cyclone separator, the dry material is discharged through the discharge air shut-off device, and a part enters the briquetting system and is extruded into blocks. Forming the finished product. Another part of the material enters the anti-blocking fuel feeding device, and is sent to the hot blast stove through the fuel feeding fan, and under the action of the cyclone-enhanced combustion fan, the combustion is completed and the high-temperature flue gas is formed, which is used as the whole drying system. The exhaust from the cyclone is discharged into the atmosphere.
