Product Description

Open Two-Roll Rubber Mixing Mill

3寸炼胶机.png
A. Introduction 

    A rubber mixing machine with exposed rollers used in rubber factories to prepare plasticized rubber, mixed rubber, or heat-cured and molded. The main working parts are two hollow rollers or drilling rollers that rotate inward in different directions. The one installed on the operator's side is called the front roller, which can be moved back and forth horizontally by manual or electric action to adjust the roller distance to meet the operating requirements; The rear roller is fixed and cannot move back and forth. The size of the two rollers is generally the same, and they rotate relative to each other at different speeds. The raw rubber or rubber material is drawn into the gap between the two rollers with the rotation of the rollers, and is subjected to strong shearing to achieve the purpose of mastication or mixing. Mills are also used in sectors such as plastics processing.
