Rotary Drying Machine
Rotary Drying Machine, also named rotary drum drier, it is a heating and drying device for material. Were widely used in cement, mining, building materials, chemical industry, drying coal, limestone, grain, sand, clay and other materials.
Roller Drum dryer
The main part of the drum dryer for a slightly sloping rotating cylinder.cylinder rotating by gear transmission, speed is commonly 2 ~ 6r/min, the gradient of cylinder related to its length, usually between 1 ° ~ 5 ° between. Material were feeding into from the higher side of the drum, and fully-contact with hot air, along with the rotationg cylinder, materials was dry and eduction under the force of gravity flow to the lower end . As the dryer were working under the negative pressure conditions,so feeding and discharging end all use sealing device to avoid air leakage.
Composition:
Drum dryer mainly consists of Revolved Body, raise material plate, gearing, supporting device and seals ring and other parts.
Working Principle:
Dry wet materials by belt conveyor or bucket elevator transfer to hopper and then to the feeding end by hopper of feeding machine through charging pipe .
Feeding pipeline slopping angle should max than the natural angle, in order to materials smoothly into dry containers.
Rotary dryer is a revolving round drum with a small slope.matrial from the high side into the pipe and heat-carrying agent into is from the low end,counter-current contact with material,also material can flow into the drum pipe with heat-carrying agent.
Along with rotate of the round drum materials run to the bottom of the end by gravity .when.the wet material moving forward in the pipe,can get the heat from the heat-carrying agent directly or indirectly to make the material dry,then discharge the material by the belt conveyor or screw conveyor.
