HKSH roller 3 cylinder sawdust rotary drum dryer

1.Make the most of waste heat 2.Decrease heat loss 3.Increase the transfer area 4.Low energy consumption

HKSH roller 3 cylinder dryer is mainly used for drying certain humidity and granularity materials. Such as sand from mortar , various size foundry sand from casting , blast furnace slag and granularity clay-beaded sand from building department ,and granularity materials which has no chemical change ,it can resist high temperature and not be polluted by dirt from chemical industry .According to various requirements on moisture content of different department HKSH roller 2 cylinder dryer can control moisture content below 1-0.5%.

Work Principles:

HKSH type 3 cylinder dryer introduces Germany Krupp Heat Exchange technology, the dryer is assembled by 3 concentric cylinders which halved together with different diameters Its structure makes its-self is a thermal insulation system.The surface of the two inner cylinders give off heat to the outer cylinder that can make heat exchange come true . And the outer cylinder in low temperature , so heat loss of the cylinder is remarkable.
