There have been internal mixers with speeds up to 80rpm or even higher, as well as dual speed, three speed, and variable speed internal mixers with extensive adaptability and treatment methods for process and efficiency, as well as internal mixers with adjustable rotor speed ratios. Its operating time has been greatly shortened, from 8-15 minutes for slow machines in the past to 1.5-3.5 minutes, and some even reach 1-1.5 minutes (including the process of combining internal mixing and supplementary mixing).
The structure of the internal mixer is also constantly developing. The working process of the internal mixer and the mechanization and automation level of the entire unit are also constantly improving, using program control. Currently, computer control is used in large imported machines.
In short, this development is greatly strengthening the mixing process, improving machine efficiency, reducing physical labor, and improving the working environment.
