AI Technical Summary
Existing fluidized bed jet mills are prone to creating a positive pressure state during the feeding process, which can cause material to be ejected and pollute the environment. In addition, excessive air volume from the induced draft fan can cause unqualified coarse particles to enter the product, affecting product quality.
The system employs a check valve and a support mechanism, and controls material conveying through the cooperation of upper and lower pneumatic butterfly valves. Combined with the design of sealing rings and support frames, it ensures that the material does not spray out under positive pressure conditions, and adjusts the air volume of the induced draft fan to meet the material particle size requirements.
It effectively prevents material ejection from polluting the environment, improves material processing quality, reduces the speed of the classifier wheel and the air volume of the discharge pipe, and enhances the stability and flexibility of the equipment.
