Project Background

In the production process of color masterbatch, plastic pellets and PVC pellets are typically at a high temperature after extrusion or pelletization. If cooling is insufficient, problems such as pellet deformation, adhesion, and agglomeration are likely to occur, which can affect the stability of subsequent packaging, weighing, and conveying.

In this case, the customer hopes to achieve fast plastic pellet cooling and stable plastic pellet conveying in a limited space, while ensuring continuous output and pellet integrity, with high requirements for equipment stability and process matching.
