How to address the powder issue in polypropylene pellets
Thread Content
There is powder in the pellets, and the powder remains in the pelletizing water. Could you please offer some advice and solutions?
In the pelletizing water tank, a lot of new powder material is removed every day – what’s going on? There are many reasons, but the situation just doesn’t get any better!
It is unclear what your specific manufacturing process and material properties are; it is speculated that the materials may be too fine, which results in excessive powder being generated during the granulation process； If the properties of the material are fixed ； You can try changing the discharge temperature and adjusting the speed of the pelletizer to see if this can reduce the amount of powder produced ； If there is no way to solve it, it is recommended to find ways on the device to reduce the workload of collecting powder ； You can talk to the equipment manufacturer; they may have encountered such a problem before ； After all, they communicate a lot with the manufacturers ；
In a normal situation in the pelletizing water tank, the water should overflow to carry away the powder; there will always be some powder present. If there is an excessive amount of it, there might be a problem somewhere. Check whether the pellets are too small, resulting in too much fine material
What is the manufacturing process? It can be replaced with a large-ball catalyst to reduce the amount of fine powder
