This machine is primarily composed of rotating bodies, feeding plates, transmission devices, supporting structures, and sealing rings, among other components. Our factory's dryer utilizes a new feeding plate device that offers guidance, even flow distribution, and feeding capabilities, enabling the even distribution of materials across the radial cross-section of the dryer. The material curtain becomes thin, even, and complete, ensuring complete contact with the hot air stream to maximize the use of thermal energy. Our dryer is designed with reasonable operating parameters, reducing coal and electricity consumption by 10-15% or more compared to general dryers, and increasing the hourly output by 10-15% or more, and has been widely applied in cement and ore selection enterprises.
