The open type rubber mixer is mainly used for heat refining, sheeting, breaking, molding, and mixing of rubber. It consists of a roller, a roller bearing, a roller pitch adjustment device, an emergency braking device, a frame, a base, a transmission device, and a heating and cooling system. The working principle of an open rubber mixing machine is that raw rubber or rubber material is pulled into the roller gap by friction between two opposing rotating rollers at different speeds, and is subjected to intense shearing and extrusion to increase plasticity. This double roller open type rubber mixing machine has been used in production since 1826. Its structure is relatively simple, and it is still widely used in modern times.
