Technical Principles and Operational Characteristics
Rubber grinding mechanically breaks down and homogenizes coagulated latex to reduce molecular weight and enhance plasticity. Mastering critical techniques—shear force control, temperature management, and repeated processing—is essential to transform tough raw rubber into pliable sheets suitable for manufacturing.

Equipment Configuration and Operational Flow
Operators first feed large chunks of gelatinous rubber into the compression zone of counter-rotating corrugated rollers. The equipment continuously shears and flattens the material through extrusion and stretching within the roller gap. Workers repeatedly fold and refeed the processed rubber, progressively refining texture and uniformity until the material achieves the desired thickness and plasticity.

Core Features and Advantages
Molecular Structure Breakdown: Mechanical shearing shortens polymer chain lengths, reducing viscosity and enhancing subsequent processing properties.
Impurity Removal: Grinding and extrusion expel residual moisture, bark particles, and gel irregularities, preventing quality defects in finished products.
Uniformity Achievement: Repeated rolling establishes stable material characteristics, ensuring reliable production performance.
Preservation Treatment: Thoroughly ground sheet-like rubber exhibits greater stability than original gel, extending market shelf life.

Key Processing Considerations
Temperature Control: Monitor roller friction heat to prevent material loss of plasticity due to scorching or premature vulcanization.
Feed Uniformity: Maintain consistent raw material particle size to ensure smooth roller contact, avoiding jams or uneven processing.
Operational Safety: Proper positioning and guarding prevent access to pinch points between high-power rollers.
Quality Grading: Visual inspection during processing identifies material defects or impurities requiring sorting.
