The material is evenly and continuously fed into the grinding chamber of the main machine through the vibrating feeder. Due to the centrifugal force during rotation, the grinding roller swings outwards and is pressed tightly against the grinding ring. The spatula scoops up the material and sends it between the grinding roller and the grinding ring. The purpose of crushing is achieved by the rolling of the grinding roller.

Existing mills, such as the common Raymond mill, when milling, firstly, the material is broken into pieces smaller than 20 mm by the crusher, and the electromagnetic vibrating feeder is quantitatively sent to the main machine of the mill. Grind inside. The grinding roller device suspended on the grinding roller frame in the main engine rotates around the central axis, and the grinding roller rotates around the grinding roller axis at the same time. Throw it between the grinding roller and the grinding ring, and achieve the function of crushing and grinding due to the rolling of the grinding roller and the grinding ring.

The cavity flows to the secondary sorting cavity, and then enters the sorting sieve through the powder passing gap on the coarse material baffle plate 33. After being sorted again, the fine powder flows from the powder outlet of the sorting sieve to the collecting cavity after passing through the sorting gap. The coarse material cannot be thrown out through the sorting gap, and after being blocked by the retaining rib 321, it is collected into the coarse particle receiving bucket 34 and then discharged from the powder mill through the discharge pipe 35 to complete the calcium hydroxide powder powder making.

Further, as shown in FIG. 2, the longitudinal surface of the rib 321 is a plane, and the angle α between the longitudinal surface of the rib 333 and the line connecting the rib edge and the center of the ring satisfies 10°≤α≤62°, The vertical surface of the sorting rib 321 is a plane, and the angle β between the vertical plane and the line connecting the edge of the sorting rib and the center of the ring satisfies 18°≤β≤70°, such as when α=13°, β =21°; when α=18°, β=40°; when α=26°, β=70°; when α=62°, β=70°, or select other angle data according to the actual situation. In this way, during the rotation of the sorting sieve, the thicker calcium hydroxide particles cannot pass through the sorting gap and are bounced to the ribs. With such an angle design, the ribs can block the thicker calcium hydroxide particles and pass through Coarse grain receiving bucket 34 is discharged from discharge pipe 35, avoiding passing through the powder passing gap and returning to the cavity of the secondary separator.
