How to solve the problem of gas expansion when superfine powder is packaged?
Super fine powder in the packaging will appear in a large number of gas specific gravity of ultra light, water shape, conventional weighing packaging machine can not packaging.
Status of ultra-fine powder packaging:
Dust is big
Insufficient bag space
Poor packing accuracy
Packaging speed is slow some powder materials, such as battery cathode materials, cathode materials, potassium perchlorate, cobalt oxide, graphite powder, extinction powder, etc. Material, floating material itself has a large number of gas, material as a whole is virtual, lead to cannot smoothly into the bag or in the process of packaging barrels, if not for mandatory bagging process will cause the phenomenon of bulge bag or torn bags, to avoid this situation, many enterprises choose to place the materials for a period of time to precipitation, and then to packing. Although long time precipitation can solve the powder can not be filled with bags and bags, broken bags, but the consumption of time is long, packaging efficiency is very low, high labor cost. It is very inconvenient for enterprises eager to ship goods. Most of the packaging machines in circulation on the market do not have exhaust degassing energy. How to do this situation? This requires degassing device to combine with the packing machine to complete powder degassing, measurement and packaging operations together.
Superfine powder packing machine, also known as degassing type weighing and packing scale, is used for weighing and packing superfine powder. It is added vacuum negative pressure degassing device and anti-dust flying mechanism on the basis of vertical spiral packaging. The main degassing methods are:
Mixing bin pre-degassing, so that the bulk density of materials increased, gas content decreased.
The vertical spiral tube sandwich gas negative pressure filter design, using negative pressure vacuum degassing and mechanical exhaust device (the size of the spiral pitch has an extrusion effect on the material), so that the material further degassing.
During the packing process, the degassing rod is automatically inserted into the bag for degassing again
After degassing, the bags are automatically pulled to the degassing station for final degassing.
