Product Description

Rubber Refining Mill

Our Rubber Refining Mill is a heavy-duty, precision-engineered machine designed for the mastication, blending, and sheet formation of rubber compounds. Serving as a cornerstone of rubber processing, it is essential for transforming raw rubber, reclaim, or compound mixes into a uniform, pliable, and consistent sheet ready for the next stage of production. Its robust construction and precise control make it indispensable for producing high-quality rubber products across various industries.

Specification

Core Function: Precision Mixing and Homogenization

1.Plasticizes the Rubber: Breaks down the polymer chains, making the rubber soft, pliable, and easier to process (mastication).
2.Disperses Additives: Ensures the uniform distribution of carbon black, oils, sulfur, accelerators, and other chemicals throughout the compound.
3.Develops Compound Properties: The shearing action helps to develop the necessary physical properties in the rubber compound, such as tensile strength and elasticity.
4.Produces Uniform Sheets: Forms a consistent, continuous sheet of a predetermined thickness and width for calendering, extrusion, or molding.

Key Features & Technological Advantages

1.Robust Construction: Heavy-duty frame, high-strength steel rolls, and powerful gearing ensure reliable performance under continuous high loads.

2.Precision Temperature Control: Advanced cooling/heating systems maintain exact roll temperatures for consistent compound viscosity and quality.

3.Adjustable Roller Gap: Micron-level gap setting (nip) allows for production of sheets with precise thickness specifications.

4.Friction Ratio Drive: Counter-rotating rolls operate at a defined speed differential to generate essential shearing and blending action.

5.Comprehensive Safety: Integrated emergency brakes, safety bars, and guards ensure operator protection and meet top industry standards.

6.Material Versatility: Processes a wide range of materials, including natural, synthetic, and reclaimed rubber (e.g., from tires), as well as EPDM.
