Rotary Drying Machine Description
The rotary drum dryer is mainly used for drying compound fertilizers with a certain humidity and particle size. Besides, drying other powder and granular materials is also available. With the unique advantages of high yield and reliable operation,rotary drum drying machine is the ideal equipment for mass compound fertilizer production. Good Drying Effects of Rotary Drying Machine
Rotary Drying Machine has the ideal drying effects for fertilizer particles. After drying, fertilizer particles are of high strength and good for storage.
* For compound fertilizer: After drying, the moisture content will be reduced to 2%-5% from 20%-30%.
Rotary Drying Machine Features
* Rational distribution and design of the lifting plate ensures high utilization rate of heat energy.
* the Rotary Drying Machine has wide application range, our rotary drum drying machine has a strong adaptability of materials and can be used to dry various materials.
* The hot air passes through the rotary drum body with small resistance, thus has low energy consumption.
* Continuous and reliable operation, large capacity.
* Less fault, convenient maintenance and low repair cost, long service life.
* Realizing mechanization and automation operation with good drying effect.
Working principle of rotary drying machine
rotary drying machine adopts direct heating air with heat soure from firing unit. The material to be dried is pushed immindiately by spiral board when materials enters the shell. Because the rotary dryer is installed in slope,meanwhile, rotary drying machine is lifted by board repeatedly up and down accordingly, which make the material mix evenly with the hot air and exchange heat sufficiently. In the end, the moisture in the material is dryed by repeatedly scattering.
