USAGE AND BENEFITS OF ROTARY DRUM DRYER
WORKING OF ROTARY DRUM DRYER
The material is fed in the rotary dryer by the conveyor, and when it’s coming through the cylinder, the hot air will flow from it and makes it dried,. The dried material will be collected at the output. In this drying process, the material will move as the cylinder rotation. With the gravity, the material will fall from highend to low-end. There are also copy boards in the dryer to raise the material, so that the material and hot air’s contact surface area increases, which helps to increase the drying rate .
USAGE OF ROTARY DRUM DRYER Used For Drying Construction and Engineering Raw Material Used For Drying Industrial Products Or By Products Processing Of Mineral Products After Mining. Used to dry Agriculture and Forest Waste
Coal
FUEL USED BY ROTARY DRUM DRYER
Coal, the most versatile and costeffective fuel, can generate heat of 5000 kcal/kg.
Gas Gas includes all combustible gases such as natural gas, biogas and coal gas. Its heat is about 8500 kcal/cubic meter with high combustion efficiency, less air pollution and slightly higher comprehensive cost than that of coal.
Biomass Biomass fuel made of wood raw materials, generally has a low calorific value of 3000~4500 kcal/kg. Its cost is a little more than that of coal, about the same as gas fuel, and is not restricted by pipelines.
BENEFITS OF ROTARY DRUM DRYER Drum dryers are easy to operate and maintain. Drum drying can be clean and hygienic Drum dryers normally have high energy efficiency Good porosity and good rehydration due to boiling evaporation
