Working Principle of Rotary Dryer
The material was sent to hopper by belt conveyor or bucket elevator and then by the feeding machine of hopper through charging pipe into the feeding side.
The slope of feeding pipeline from rotary dryershould bigger than the materials' natural dip angle, in order to sand smoothly flow into the dryer machine.
The drum of rotary dryer is a rotary drum which is slightly obliquely with the horizontal line. Add the materials from the higher side, heating body goes into the lower end, form countercurrent contact with materials, also exists the heat body and materials together concurrent flow into the barrel. Along with the cylinder rotating, the materials move to the lower end by gravity.
During the moving process of rotary dryer, wet materials in the cylinder directly or indirectly got heat from the heating body, make wet materials to dry, then in the discharging end the materials were sent out by belt conveyor or screw conveyor.
