Coal dryer is now hot equipment in the world. Coal is vital energy resource in various industries and daily life. When coal is washed or stored in open yard, some is washed away which forms coal slime later. This is a great loss. Coal slime is of high moisture and low heat, which means poor economic value. However, coal dryer solves this problem perfectly.
Under normal conditions, moisture inside of coal slime is 20-30%. After drying, the moisture can be reduced to 0.1%. Thus, coal slime can be used in many occasions. Coal dryer turns waste into treasure.
How does coal dryer work?
Coal dryer is divided into several sections for higher efficiency.
A. Transmission section. Wet material enters coal dryer, then it gets full contact with hot air, moisture inside gets vaporized. With lifting boards elevating and scattering materials repeatedly, wet material is conveyed to next section.
B. Cleaning section. When materials fall down, they are easy to stick on the inner wall of the cylinder. During this process, cleaning device breaks the clumps. This spreads the surface area of heat exchange and improves heat efficiency.
C. Lifting boards section. Wet material gets loose and of low moisture content that meets the requirement.
D. Discharging section. No lifting boards in this area. Materials roll to the outlet coal dryer. The whole drying process is completed.
