The invention discloses a dry-process sand mill, and relates to the technical field of material crushing and
grinding, the dry-process sand mill comprises a
machine body, the
machine body is provided with a feeding device, a
grinding device, a discharging device and a driving device, the
grinding device comprises a stirring shaft which is rotatably arranged, the stirring shaft is provided with a stirring
assembly, and the stirring
assembly is provided with a feeding device and a discharging device. The stirring
assembly comprises a plurality of stirring discs which are arranged at intervals in the axial direction of the stirring shaft, a plurality of uniformly arranged stirring blades are installed on the stirring discs in the circumferential direction, the working face of each stirring blade is of an arc-shaped structure, and the
radian direction of each stirring blade is matched with the rotating direction of the stirring shaft; the invention provides a
dry sand mill which comprises a plurality of axially arranged stirring discs and a plurality of stirring blades uniformly and circumferentially arranged on the stirring discs, and the working surface of each stirring blade is of an arc-shaped structure, so that aggregates can be effectively impacted, the condition that uncrushed coarse particles and fine particle aggregates exist in products is avoided, and the product quality is improved. And meanwhile, the uniformity of
particle size distribution of the product is ensured.
