What is Rubber Mixing Mill?

A rubber mixing mill is an open-type, two-roll machine used in the rubber and plastic industries to process raw materials by plasticizing, mixing, refining, and sheeting. It mixes rubber polymers with additives (oils, fillers, vulcanizing agents) by passing them between two horizontal rollers rotating at different speeds in opposite directions

Key Components: Consists of a frame, two horizontal rolls (usually chilled cast iron), a driving gear, a lubrication system, a roller nip adjustment device (for controlling the gap), and safety brakes.
Process Operation: The raw rubber is fed into the nip (gap) between the rollers, mixed, and then manually or automatically cut and folded back, ensuring a consistent mixture.
Temperature Control: Rolls can be heated or cooled (via steam or water) to manage the compound’s temperature, which is crucial for preventing premature vulcanization.
Safety Features: Equipped with emergency brake systems to ensure operator safety, such as rod or knee-operated stops.

“MODERN mixing mills are equipped with a specially designed hydraulic stock blender to assist the operator in mixing the rubber material and chemical powder. It reduces the labor indulgence, provides safer working conditions, lowering the material temperature and speeding the mixing rate of the compounds.
The speed of the stock blender can be changed as per requirement irrespective of the roll rpm.”
