The invention discloses a battery negative electrode material mixing device with cyclic grinding equipment. The battery negative electrode material mixing device comprises a mixing chamber; a discharge pipe is arranged at the bottom of the mixing chamber; a stirring mixing device is arranged inside the mixing chamber; the stirring mixing device is composed of a bottom scraper blade, a through hole, a first vertical rod, a second vertical rod, a stirring shaft, a spiral stirring blade and a stirring motor. The battery negative electrode material mixing device is simple in structure, reasonable in design and convenient to use; due to arrangement of a grinding chamber, materials can be ground, a filter plate at the bottom of the grinding chamber can filter out qualified materials obtained after grinding, then, small and large materials are separated out through an inclined plate, large-particle materials can be input into the grinding chamber again through a cyclic feeding device, secondary grinding treatment is performed, small-particle materials are separated out through the inclined plate to be input into the mixing chamber, and the materials and additives are mixed; the stirring mixing device can greatly increase the material mixing speed, the material production time can be shortened, and the production rate can be increased.
