Description

TECHNICAL FIELD

[0002] The regenerative rubber mixing mill for rubber tire preparation is a core equipment in the rubber industry, mainly used for plasticizing, mixing, heat mixing, sheet pressing and glue supply of rubber, and also can be used for crushing, kneading and refining in the production of regenerative rubber sheet. It can carry out physical and chemical reactions on the unprocessed rubber raw materials and various additives (such as vulcanizing agent, filler, plasticizer, stabilizer, etc.) under high temperature and high pressure, so that the rubber molecular chain is broken and recombined, so as to realize the conversion of rubber raw materials and prepare the glue that meets the production demand of various rubber products. This equipment plays a key role in the manufacturing process of rubber products such as tires, rubber pipes and sealing elements, and the adjustability of its process ensures the diversity and applicability of the glue performance.
