The process of an open mill is relatively simple. Initially, raw rubber is placed between the two roller cylinders, and then the rollers are driven to rotate through a transmission system. Under the shearing, friction, and extrusion forces of the rollers, the raw rubber is gradually plasticized and moves as the rollers rotate. During its movement, the rubber raw materials are treated at various temperatures and for different durations to achieve the desired mixing effect. The open mill then discharges the processed rubber raw materials, completing the entire process.
The advantages of open mixers include their simple structure, ease of operation, and excellent mixing results. Additionally, due to their unique working principle, open mixers also boast the following benefits:
Uniform Mixing: During the mixing process, the rubber raw materials are subjected to various forces between the two rollers of the open mill, resulting in a more uniform blend.
Adaptable: The open mill is capable of accommodating various types and hardness of rubber raw materials, ensuring excellent mixing results under all circumstances.
Adjustment Convenience: The roller spacing and speed of the open mill can be adjusted via the distance adjustment device to accommodate different thicknesses of rubber raw materials and various blending requirements.
However, open millers also have some drawbacks, such as low production efficiency, high labor intensity, and poor operating conditions. These issues have led to the fact that open millers are no longer fully meeting the demands of modern industrial production.
