Small open mill is a mixing process that enables the product to meet the quality and color required by the customer. After the customer's requirements are met, the experimental results and their ratios are used in the production line. This equipment is to mix the test raw materials and additives.

Open mill was an open-type rubber kneading machine used by rubber factories to prepare plastic smelting rubber, mixing rubber, or performing hot smelting and molding.

The main working parts are two rollers that rotate in opposite directions. The device is called the front roller on the operator's side. It can be moved back and forth by manual or electrical action to adjust the roller distance to meet the operating requirements. The rear roller is fixed. , Can not be moved back and forth. The two rollers are of the same size, and each rotates at different speeds. The rubber is rolled into the gap between the two rollers as the rollers rotate. Open mills are also used in industries such as plastic processing.

    In the plastic products industry, people are used to calling it a two-roller machine. Opening mill is a kind of mixing plastic equipment which is applied earlier in plastic product manufacturing plants. In the calender production line, the role of the open mill before the calender and after the mixer is to mix and plasticize the mixed raw materials to provide a more homogeneous melt for the calendering and molding of plastic products. In the production of cable materials, the open mill can mold the powdered material mixed according to the formula into a molten material. And then press-mold it into a sheet belt to cut the pelletizer into granules. In the floor leather production line, it can provide the base coat for mixing and plasticizing for bucky leather. The recycled waste plastic film (sheet) can also be re-molded on the open mill and re-made.
