Single Stage Mixing and Production Line, mix master batch in the mixer , then continuously mixing and compounding in mills. It realize whole mixing process from raw material to final batch, automatically and continuously, in one step. This system can improve quality and productivity of compound at the same time. Long time mixing in mills , raise decentrality of additives and chemicals, increase stability and homogeneity of rubber compound. At the same time , heighten abrasion resistance and rolling resistance performance.
