Plastic powder air screen / clay air screen

  Brief introduction of pneumatic screen pneumatic screen is a kind of high-precision screening equipment for screening fine powder
It is widely used in chemical industry, medicine, food, papermaking, metallurgy, building materials, rubber, machinery and other industries
It can be used for continuous screening of powdery materials with fineness ranging from 80 to 500 mesh, and the screen can be changed at will
The air flow screen (air flow screen) has high screening efficiency, large output, accurate fineness, no over diameter mixing phenomenon, no load on the vertical installation of the screen, long service life, wide range of fineness, fully enclosed structure, no dust overflow, low noise, low energy consumption, continuous operation and convenient maintenance

In the traditional sense, the vibrating screening equipment relies on a certain frequency of motor vibration to realize the classification of granular objects through the screen
Due to the open screening, the dust in the material screening process is large, which virtually causes waste and loss in the material screening process, and leads to great pollution of the natural environment and working environment
At the same time, vibration screening has great requirements for materials, such as specific gravity, viscosity and chemical properties, which leads to many materials with small specific gravity cannot pass through the screen, and many materials with high mesh screening requirements cannot be screened

It is widely used in chemical industry, medicine, food, papermaking, metallurgy, building materials, rubber, machinery and other industries
It can be used for continuous screening of powdery materials with fineness ranging from 80 to 500 mesh, and the screen can be changed at will
The air flow screen (air flow screen) has high screening efficiency, large output, accurate fineness, no over diameter mixing phenomenon, no load on the vertical installation of the screen, long service life, wide range of fineness, fully enclosed structure, no dust overflow, low noise, low energy consumption, continuous operation and convenient maintenance

Pneumatic screen should screen materials
Graphite powder, resin powder, traditional Chinese medicine powder, coating, fly ash, talc powder, industrial drugs, cosmetics, fire extinguishing agents, plastic powder, clay, abrasive, aluminum powder, glass powder, refractories, starch, milk powder, metallurgical powder, electromagnetic materials, copper powder, carbon black, activated carbon, light calcium carbonate, iron ore, etc

Working principle of air flow screen
The air flow screening machine discards the operation principle of gravitational potential energy and adopts the operation principle of air as carrier and kinetic energy as work
After mixing the material and air through the negative pressure air flow, it enters the middle of the fan wheel of the screen machine, and applies sufficient centrifugal force through the blade of the fan wheel to spray the bucket screen and collect it through the volute
Oversized materials cannot pass through the net and are discharged from the automatic slag discharge port, so as to achieve the purpose of rapid screening

The vertical air flow screen is suitable for the screening and classification of various powdery materials with 80-530 meshes
It has high screening efficiency, large output, automatic feeding and discharging, continuous operation and no pollution, making it difficult to carry out high-precision screening with various vibrating screens in the past
After screening and using 120-180 mesh light calcium, 300 mesh heavy calcium, 400 mesh active calcium, 300 mesh hawthorn powder, 320-500 mesh zinc powder, 500 mesh iron oxide black, iron oxide red, 120-160 mesh traditional Chinese medicine powder, 180-270 mesh quartz powder and other materials, the hourly output per square meter of screen area is measured to be about one ton, at the same time, the screening efficiency is measured to be more than 95%, and the air dust content is less than 10mg/m3
