and the second prior art is as follows: the application publication No. CN113493620A discloses an intelligent granulating device for low-hardness carbon black particles, which drives a reaction inner cylinder to rotate in a reaction outer cylinder by arranging a rotating mechanism, so that stirring teeth can fully stir and react with carbon black powder to enable carbon black to be combined into particles, and the synthetic size of the carbon black particles can be changed by arranging stirring teeth capable of changing angles on the reaction inner cylinder, thereby realizing production of the low-hardness carbon black particles and controlling the particle size of granulation;
to the above-mentioned unable particle diameter of controlling the granulation problem, prior art two has given corresponding solution, but its length that stirs tooth (i.e. threshing bar) is changed through the slope in fact, in order to change its length and go to slope stirring tooth, there is the too big condition of inclination, too big inclination can increase energy consumption and granule wearing and tearing, also can lead to excessively mixing simultaneously to destroy the granule structure, and the carbon black granule of its synthesis does not have the mould that can correspond the regulation to carry out real-time screening and discharge, need to adjust repeatedly according to the demand when carrying out batch production on the production line, still influence the production progress when wasting time and energy.
