In the process of mixing the raw materials of magnesia carbon bricks, a sand mixer with diversion mixing is required.

[0003] However, when the existing diversion mixing sand mixer is used, the raw materials are poured into the mixer and the raw materials are fully mixed by rotating the internal stirring rod.

The raw materials cannot be diverted to multiple mixing chambers for separate mixing, resulting in low mixing efficiency. Utility Model Content

When it is necessary to transport raw materials to the third chamber, it is only necessary to make the splitter plate 8 It contacts the first ball wall and the third ball wall. At this time, the first discharge pipe 6 is in a closed state and the second discharge pipe 7 is in a flow state, which will send the raw materials to the third chamber. The flow states of the first discharge pipe 6 and the second discharge pipe 7 are controlled by the different positions of the diverter plate 8 in the transfer device 4, so that raw materials of different quantities flow to the corresponding chambers, realizing the control of the diversion, which is easy to use. After the raw materials are added, the raw materials in the second chamber and the third chamber are mixed by rotating the first stirring rod 2 and the second stirring rod 3, completing the use of the sand mixer for this diversion and mixing.
