        Development History of Open Mill

        2023-06-12

        The full name of the open type rubber mixer is one of the basic equipment in the rubber industry and one of the three major rubber refining equipment. It is a basic rubber machinery that has been used early and has a relatively simple structure in the rubber industry. As early as 1820, there was a single roller trough type rubber mixing machine driven by manpower. The double roller rubber mixing machine was applied in rubber processing and production in 1826, and has a history of over 180 years to this day. The design and manufacturing of large-scale refineries in China began in 1955. In the past fifty years, the design and manufacturing level of refineries have greatly improved. In recent years, there has been a continuous emergence of domestically produced new structural opening mills. It has effectively promoted the development of the refining machine. So far, domestic refiners have become a series, and some specifications have been finalized and designed, and have been exported to foreign countries.
