The rotary dryer is composed of stove , main rotary body, which can reduce moisture from 50% to 10%. The moisture evaporating capacity of our rotary drum dryer can reach to (250kg per hour to 8000kg) per hour. Different density materials, the final product are not the same; also for different moisture of raw materials, which could get the different final capacity.
1. It can use chemical gypsum (Free gypsum dehydration, phosphogypsum etc) to fry β-semi-water gypsum directly.
2. From craft process, guarantee the requests of frying temperature and time which should make precise control in roasting the gypsum.
3. The discharging of work machine is designed rationally, when operation, there is no dust pollution.
4. When interval feeding and discharging, it can be banked fire and shut down furnace. The stove fire can be put into normal production after 3 minutes by again opening furnace.
5. Matched gas stove or fluidized bed furnace is used for supplying heat, the waste heat of tail gas can be used recycling. (Boil water, heat the air.)
