In order to solve the phenomenon of powder overflow of vibrating screen, it is necessary to find out its cause. Vibrating screen generally adopts the way of adding negative pressure to control dust, adding negative pressure can solve the powder in the vibrating screen inside the situation of dust, dust itself is relatively small, so the effect is more general. Lead to the emergence of vibrating screen powder machine dust or powder leakage phenomenon mainly from the following two processes: feeding dust and receiving dust. Now, the artificial material is larger than the artificial feeding of the dust, the material from the vibrating screen equipment is very small vibration dust, but the material fell into the pocket and open the cylinder of the secondary dust volume is appropriate, difficult to control, great harm.

The dust problem of the powder vibrating screen needs to be analyzed and controlled from the aspects of feeding, receiving, and transportation. At present, many production enterprises that do not have a considerable scale will choose a more economical and concise method of manual feeding and receiving when feeding materials, which is the main reason for the phenomenon of powder leakage in the powder vibrating screen, and the operation process of manual feeding is not conducive to Screening, screening equipment continues to uninterrupted quantitative feeding until demand. Generally, manual feeding is to add a lot of materials at once, and let the equipment perform screening. Screening is almost like feeding again. Such screening operations not only cause a lot of dust to fly. , it will also constitute a decrease in the output value and power of the screening equipment (the output value of metal powder decreases by more than 60%).
