Slurry rotary drum dryer equipment
Product Description
Rotary dryer, also called rotating cylinder drying machine, which is mainly used for mineral processing, building materials, metallurgy, chemical, cement industry and other departments drying certain wet degree or the size of material. Rotary dryer is mainly consisting of rotary body, raw material feeding plate, driving and supporting device, etc. Rotary dryer strong adaptability to raw materials can be drying a variety of materials, and the equipment is simple and reliable, so widely used. It is of high efficiency and has the features of reasonable structure, high capacity, low consumption easy operation, etc. It can make final products free from dirt and impurities and reduce the high quality sand loss.
Main features
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.
.
Working Principle
Rotating cylinder dryer is a new type continuous dryer which designed on foundation of absorbing foreign technology. The machine is equipped 3 sets inner barrel. Raw material fed from screw import, under the function of rake and hot air flow, raw material will get enough heat and mass transfer after second deflection. Dried product will be collected by cyclone separator of bag filter, damp air will be exhausted by fan.
