Rubber mill edit

There are two types of rubber mixers: open and closed. The open type machine is mainly used for the thermal smelting, tableting, breaking, plasticizing and mixing of rubber. The open type rubber mixer has been used for production since 1826. Its structure is relatively simple, and it is still widely used in modern times; closed The rubber mixing machine is mainly used for rubber mixing and mixing. It has one more mixing chamber than the open rubber mixing machine. Since the invention of the oval rotor sealed rubber mixer in 1916, the sealed rubber mixer has developed rapidly in the rubber industry, and later other types of rotor sealed rubber mixers have appeared. The mixing cycle of the modern closed-type rubber mixer is 2.5 to 3 minutes, and the maximum capacity of the mixer is 650 liters.
