Open mill Open mill is the abbreviation of open plastic refining machine. In plastic products factories, people are accustomed to calling it a two-roller machine. The open mill is a relatively early type of plastic mixing equipment used in plastic product manufacturers. In the calender production line, the function of the open mill before the calender and after the mixer is to mix and plasticize the uniformly mixed raw materials to provide a relatively uniform molten material for mixing and molding of plastic products rolled by the calender. When producing cable materials, the open mill can directly refining the powdered materials mixed according to the formula into molten materials and then press-molding them into sheet-like ribbons for the pelletizer to cut into granules. The floor leather production line can directly provide cloth-based leather with evenly mixed and plasticized base coatings. The recycled waste plastic films (sheets) can also be re-refined in an open mill. The open mill has a simple structure, is relatively easy to operate and master, and is easy to repair and disassemble, so it is widely used in plastic products companies. The disadvantage is that workers consume a lot of physical energy to operate and need to manually mix and turn the materials in a higher temperature environment. The number of times the plastic sheets are manually turned over has a greater impact on the quality of the raw materials.
