XSG series rotary flash dryer
working principle
The hot air tangentially enters the bottom of the dryer and is driven by the agitator to form a powerful rotating wind field. The paste material enters the dryer by the screw feeder. Under the strong action of the high-speed rotary stirring paddle, the material is dispersed by the impact, friction and shearing force, the block material is rapidly pulverized, and it is in full contact with the hot air and is heated. ,dry. The dehydrated dry material rises with the hot gas flow, and the classification ring intercepts the large particles. The small particles are discharged from the center of the ring to the outside of the dryer, and are recovered by the cyclone separator and the dust collector. The dry particles or the bulk material are subjected to centrifugal force to the wall. , fell to the bottom and was crushed and dried.
