rotary drum dryer used for drying manure,fertilizer,sludge with high efficiency

rotary dryer is Mainly used for drying wet materials in building construction, metallurgy,wood sawdust,animal manure,fertilizer granules and so on. the rotary drum dryer Can dry various materials with strong adaptability Besides, the rotary drum dryer machine is a common drying equipment in cement plant with simple and reliable operation which Applies the new type scatter plate device and with various functions, such as guide direction, flow on an average, scatter the material and what is more the rotary drum dryer Can make the material in the thin, average and complete condition Contact the heat airflow completely and use the heat energy fully Moreover,the manure drying machine adopts reasonable operational parameter, and compared with general dryers, it reduces the coal and power consumption above 10 to 15% and increase the output above 10 to 15% At present, the rotary drum drying machine is widely used in cement and mining industries,and used with fertilizer pellet mill in fertilizer production plant to produce compound or organic fertilizer granules

working principle of rotary drum dryer

1.Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. China best Brewers grain dryer /Brewers grain rotary drum dryer/Brewers grain drying machine
2.When the material gets high enough to roll back off the fins, the raw materials falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.
3.This hot air can either be moving toward the discharge end from the feed end , or toward the feed end from the discharge end .
4.The hot air can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. China best Brewers grain dryer /Brewers grain rotary drum dryer/Brewers grain drying machine
5.Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.
6.When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.
