Powder is one of the existing forms of many materials. Other materials are solid or liquid. Because the powder is light, it is easy to overflow, do not touch the screen surface, and do not discharge materials. Generally, the finer the particle size of the powder, the more difficult the screening is. At the same time, powder leakage, dust and other phenomena may occur during the screening process, which is relatively harmful to the workshop environment and human health. In recent years, China's work in environmental protection is also relatively strict, so the vibrating screen needs to change to the direction of environmental protection.
In order to solve the phenomenon of powder overflow of vibrating screen, it is necessary to find out the causes. The vibrating screen generally uses the method of adding negative pressure to control the dust. The method of adding negative pressure can solve the problem of dust in the vibrating screen. The amount of dust is small, so the effect is relatively general. The obvious dust or powder leakage of the vibrating screen is mainly caused by the following two processes: feeding dust and receiving dust. At present, the amount of dust caused by manual feeding is larger than that caused by manual feeding. The vibration dust is very small when the materials come out of the vibrating screening equipment. However, the amount of dust caused by the secondary flying when the materials fall into the pocket and open the material barrel is appropriate and large, which is difficult to control and is very harmful.

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 without a considerable scale will choose a more economical and simple manual feeding and receiving method when feeding, which is the main reason for the powder leakage phenomenon of the powder vibrating screen. Moreover, the process of manual feeding is not conducive to screening. The screening equipment continues to feed the materials in a constant manner until the demand. Generally, the manual feeding is to add a lot of materials at one time and let the equipment screen. The screening is almost to add materials again, Such screening operation not only causes a lot of dust to fly, but also reduces the output value and power of screening equipment (the output value of metal powder decreases by more than 60%). The above is about how to solve the problem of powder leakage in the screening process of vibrating screen.
