The invention discloses a flour mill which comprises a mill body, a stator, a first-level rotor, a second-level rotor, a spindle and mechanical seals with bearing isolating and spiral circle systems, wherein the front end of the mill body is connected with the rear end of the stator; a material inlet is formed at the front end of the stator; the stator is taper-shaped; the first-level rotor and the second-level rotor are arranged in the stator from front to back; the first-level rotor and the second-level rotor are sleeved on the spindle and are locked at the front end of the spindle through nuts; the rear end of the spindle passes through the mill body and is connected with a power part; the mechanical seals with the bearing isolating and spiral circle systems are arranged between the spindle and the second-level rotor as well as between the spindle and the mill body; and a discharging channel is arranged on the mill body at the rear end of the second-level rotor. The flour mill provided by the invention is simple in structure; the stator is taper-shaped; the first-level rotor and the second-level rotor are arranged in the stator from front to back; after materials pass through the first-level rotor, flour is milled to 0.6-1.2mm from 1-4mm; after the materials pass through the second-level rotor, flour is milled to 0.01-0.08mm; and thus the milled flour grains are small.
Description
technical field [0001] The invention relates to the technical field of powder pulverization, in particular to a pulverizer. Background technique [0002] At present, biological, pharmaceutical, chemical, beverage and other enterprises are in urgent need of a powder mill, which can grind Class I and Class II powders from 0.6 to 3.5mm to 0.05mm. The existing pulverizers are all primary pulverizers, and the pulverized powder particles are still relatively large, which cannot meet the requirements. And after grinding for a period of time, the rotor wears a lot, the rotor needs to be replaced, and the maintenance cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mill with simple structure, small powder particles and low maintenance cost. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A pulverizer, in...
