III. Working Principle of Rotary Coal Dryer

Under normal conditions, the wet material is clotty coal. If so those clotty coal should be crushed by double-shaft mixer before sending dryer. Just like the picture in following.The crushed wet coal will be deliveried into coal slurry dryer feeder by belt conveyor. At the same time, hot-air made by stove will go into dryer cylinder under the founction of induced draft fan.Along with the rotation of coal slurry dryer, wet coal will throughly making contact with hot-air, thus humidity inside of wet coal will be evaporated.Under the action of gravity, dried coal will move into the discharged hole because the coal slurry dryer is installed with 3-5 degree tilt angle. The temperature output coal is around 70-80 centigrade.

IV. The Maintenance Method for Rotary Coal Dryer

With reach rotary coal dryer manufacture experience, Guoxin will offer you professional after-sale service. Expecially maintenance is important factor during machine running.Bearing is a part of equipment which take full weight of dryer, the choice of tube have a great influence on service life and rotation rate. So it would be better if we can sure it's clear and with good sealing performance.Gear is also important device, it's the key of transmission, we should do preventive maintenance regularly, remove the rust and add lube. This method also applies to the transmission.Finally, it's cleaning dryer's inner structure regularly. Because the wet material with high moisture easily stick upon the wall of rotary coal dryer, if we don't clearn it regularly, it will be clogging in the dryer. So cleaning method is running dryer without wet materials, thus those sticky material will be dried and out off drum wall, as the same time, rapping on a barrel wall of dryer in the rules.

V. Successful Case for Coal dryer:

VI. We can control the drying effect through three aspects:

1. Adjusting the input capacity

2. Adjusting rotary dryer's rotation speed by adjustable-speed motor

3. Adjusting fan's air flow capacity
