[0002] Mixing is a process of mixing raw rubber or plasticized raw rubber with compounding agents into mixed rubber using a rubber mixer. It is an indispensable equipment in the rubber processing process. Its main function is to mix the rubber raw materials with various additives (such as fillers, plasticizers, vulcanizers, etc.) to achieve the required physical and chemical properties and provide qualified mixed rubber for subsequent processing steps (such as calendering, molding, vulcanization, etc.).
