Multi-stage steady flow type mixing system

The invention provides a multi-stage steady flow type material mixing system. The multi-stage steady flow type material mixing system comprises a material mixer, at least one material storage cavern, a material buffering bin and a metering device. And an outlet of the metering device is connected with a feeding hole of the mixer. The main shaft is provided with a plurality of stirrers which are continuously mounted along the axial direction of the main shaft; the stirrer comprises two transmission bevel gears, a main shaft bevel gear, two transmission circular gears, two large gear rings and two hollow shafts; the two hollow shafts rotate in different directions, and the numbers of bevel gears of the main shaft are different. The mixer is provided with multiple sections of stirrers with opposite rotating directions, so that the mixing efficiency is improved, and the invalid mixing power consumption is reduced. Different numbers of bevel gears are arranged on the speed difference stirrer on the main shaft, and
