Rotary dryer consists of rotary body, lifting blade, driving device, supporting device and sealing ring.The raw material enters the rotary dryer by electromagnetic vibrating feeder.
there is also a feeding chute at the inlet of sawdust rotary dryer to assit materials going down quickly.Meanwhile, the hot air generated by burner goes into the rotary dryer from heating furnace and the material get heated.usually the rotary dryer used with organic fertilizer granulator to produce organic fertilizer granules in fertilizer production line.the organic fertilizer granulator is usually disc granulator for making organic fertilizer.the wet material is loaded from one head of rotary dryer, and then it is stirred by the bafflers that is uniformly distributed in the barrel. Material is uniformly distributed and dispersed in the rotary dryer, fully contact the hot air of parallel (or counter) flow, so the drying process is expedited, and the impulsion power of media transfer is enhanced. During the drying process, material is under the effect of angled baffler and hot air, moves to the star shape unloader that is at the other head of therotary dryer.
features of rotary dryer
1. rotary dryer is widely used for drying material with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. It can be used for drying many kinds of materials such as limestone slag, coal powder, clay stone etc.
2. rotary dryer has advantage of reasonable structure, high efficiency, low energy consumption.
3. rotary dryer mainly consists of rotary body, raw material feeding plate, lifting blade, driving and supporting device, sealing ring and etc.
