Drying equipment mainly compose of induced draft fan, broken up device, belt feeder, feeding machine, rotary drum, heat, belt discharge machine, unloader and distribution cabinet.
The rotary drum dryer equipment’s work area is quite simple which is composed of the material area; tilt spreading board area, cleaning up area, guide material area.
The material area: The drum dryer does not set the spreading board in this area, the material in this area nesting population scroll slide to complete the drying process.
The tilt spreading board area: Wet slime in this area has shown a low water loose state, the material in this area do not have the phenomenon of bond, through heat exchange materials achieve the required water status and then go into the final discharge area .
Clean up area. Wet coal slime be spreaded at the spreading board form the material screen state, the material is easy to form bonding phenomenon with the drum in this area when it is down the wall, because of the cleaning device designed in this area, the material adhere on the wall would be reasonably cleaned, in this process, the cleaning device also play the role of fragmentation for the agglomeration of materials group, thereby increase the heat exchange area, improve the drying rate.
Guide material area, wet coal slime contact with the high temperature and the hot air when it go into this area and rapid evaporation of water, the material spreaded move by a large lead angle spreading board, go into the next work area before the bond formed.
