Mixer

A material mixing machine is characterized in that a gear ring is fixedly installed outside a circular material barrel of the material mixing machine, two annular rolling wheels are arranged on the two sides of the gear ring, two sets of carrier rollers are installed on a base, the two annular rolling wheels are supported between the two sets of carrier rollers, the gear ring in the middle is meshed with a gear below, and the gear is driven by a gear motor to rotate. The circular charging barrel of the mixer rotates between the carrier rollers close to the base, the mixing height is reduced, the carrier rollers and the annular rolling wheels can provide stable rotating support for the circular charging barrel, the problem that in the background technology, a connecting bearing of a mixer is large in load is solved, and the mixing efficiency is improved. The stability of material mixing is ensured, and the material mixing effect can be improved; and the charging barrel assembly of the mixer is arranged on the
