Introduction of Gypsum Dryer
Our gypsum dryer system can be used to dry the FGD gypsum, phosphogypsum, sulfur gypsum, syn gypsum, gypsum slag, gypsum sludge and can be also used to dry kaolin, clay, bentonite, etc.
After drying, the moisture of gypsum can be ≤5%, and the particle size can be controlled below 8mm. And dried gypsum can be used as cement additives in the cement manufacturing industry, and can be used in the wallboard manufacturing industry, etc. Gypsum dryer of our company is an environmental dryer with the features of reliable performance, low fault rate, stable operation, high efficiency and low electricity consumption.
Importance of Drying Gypsum
1. Drying gypsum hardens the material and avoids congesting equipment in future steps, such as grinding;
2. The drying process prevents the matrial from some handling issues such as clumping. Drying also forms a strong pellet that is capable of breaking down quickly;
3. The tumbling action within the gypsum dryer rounds and polishes the pellet, helps to create a uniform, premium product.
Advantages of Gypsum Dryer
01
High Thermal Efficiency
Downstream drying feeds flue gas and material into the drum from the same side for high thermal efficiency.
02
Stable & Cost-Effective
Stable operation with strong processing capacity, low fuel consumption and low drying cost.
03
Controllable Output
A new internal structure strengthens material cleaning and reduces wall sticking; product size and moisture can be controlled, with gypsum moisture at or below 7% and particle size below 8 mm.
04
Customized
Gypsum rotary dryers can be customized to fit specific processing needs, including size, capacity, and temperature requirements.
05
Multiple Heat Sources
Coal, biomass pellets, natural gas, diesel, and other heat sources are available.
06
Low Investment & Fast ROI
Low equipment investment and operating cost with quick return on investment.
Working Principle of Gypsum Dryer
Gypsum dryers system of our company mainly consists of a heating machine, conveyor, feeding part, drum dryer, discharging part, and dust collector, etc.
The gypsum dryer is divided into the following working areas during the drying process:
1.In the material guiding working area, gypsum enters into the roller and fully contacts with the high temperature hot air here to evaporate water rapidly.
2.The cleaning area; The cleaning device and crushing device in the cleaning area can effectively clean and crush the materials sticking to the inner wall, thus increasing the heat exchange area and improving the drying efficiency.
3.Inclined material lifting area; where the gypsum has a low moisture and loose state, and after full heat exchange, it reaches the required moisture.
The discharging area; where the material rolls and slides to the discharge port to complete the whole drying process.
