Energy Saving Intermittent Industrial Drying Equipment For Coal Slime
 
Equipment Introduction:
 
Energy saving Intermittent industrial drying equipment is improved on the basis of traditional rotary drum
dryer, the feeding, drying and discharging process of the dryer is intermittent, the drying time can be set 
up according to the temperature of drying medium, the moisture of the feeding and discharging material
and other factors. It is applicable for drying sludge, coal, sand, animal dung, fly ash, clay, coal slime,
ore, steel slag, quartz sand, kaolin clay, bentonite, sawdust, desulfurization gypsum, compound 
fertilizer and other materials by utilizing of tail gas waste heat. By adopting thermal resistant material on 
surface of shell, so as to prevent heat loss. In this way, it reduces fuel consumption, that is to say, 
energy saving.
 
Working Principle :
 
1.The corotation of the cylinder is the feeding stage when the feeder starts to work, and the feeder stops 
once the set feeding quantity is reached; 
2.And then the cylinder rollbacks and enters the stage of drying, the drying medium will be drew into the 
cylinder of the dryer by the induced draft fan at the end of the drying system, to do the heat exchange 
with the materials being lifted up constantly inside of the dryer, the evaporated moisture is taken out 
continuously by the hot air, the material to be dried to qualified moisture content after a certain period of 
time; 
3.At last, the cylinder corotates once again, the dried material is discharged from the dryer cylinder
under the push of discharging screw, one time of drying process has been finished.
