1. The rubber compound is mixed by one-time mixing method, which can improve the mechanical shearing efficiency of the rubber material, so that the carbon black and various compounding agents are more uniformly dispersed, effectively avoiding carbon black gel during the rubber mixing process , and reducing rubber molecules The occurrence of chain irreversible chemical cleavage increases the number of reversible mechanical shearing molecular, improves the breaking strength, wear resistance and fatigue resistance of the rubber compound, reduces the Mooney viscosity, and improves the physical properties of the compound and product quality. 2. Adopt the mixing mill vulcanization system, through the mixing mill series and parallel arrangement, improve the sulfur dispersion effect; 3. It can reduce the energy consumption of high energy consumption mixer for multi-stage mixing in traditional process and save about 25% electricity; 4. At the same time, the production capacity of the internal mixer is maximized. The average number of stages of the rubber compound is 1.6, that is, the production capacity is increased by 1.6 times; 5. Improve the automation of the final refining line; 6. The quality of rubber is uniform and stable; 7. Save manpower and management cost.
