[0019] When processing with an open-type rubber mixing mill 1, the raw materials are first uniformly mixed, plasticized, and conveyed to the rollers of the open-type rubber mixing mill 1. During the rubber mixing process, the main cause of the fumes is the volatilization of compounding agents under mechanical stirring and heating conditions. Commonly used compounding agents such as stearic acid, accelerators, and antioxidants all have a certain degree of volatility. These fumes contain a variety of harmful substances. When fumes are generated, the first exhaust structure 5 and the second exhaust structure 6 are activated. The first exhaust structure 5 connects to the housing through the first exhaust fan 51. 2.
