Add powder into the processing barrel (3) through the feeding pipe (5); rotate the main shaft (24) along the support plate (23), and the main shaft (24) drives the stirring paddle (17) to disperse the powder; S2, making a pair of linear shafts (18) slide radially along the support plate (23), and using the stirring paddle (17) to disperse the powder; the fan-shaped shaft (25) synchronously reciprocates along the circumferential fan-shaped direction along with the movement of the linear shaft (18), and using the stirring paddle (17) to disperse the powder; making the main shaft (24), the linear shaft (18), and the stirring paddle (17) on the fan-shaped shaft (25) reciprocate to move closer and farther, and the main shaft (24), the linear shaft (18), and the stirring paddle (17) on the fan-shaped shaft (25) interact with each other to disperse the agglomerated powder; S3, the powder after being dispersed enters the upper filter screen (13), and is filtered once by the upper filter screen (13); the powder that cannot pass through the upper filter screen (13) flows to the lower filter screen (11), and flows to the middle discharge pipe (4) through the lower filter screen (11), thereby achieving classification of the powder; the ultrafine calcium carbonate powder filtered by the upper filter screen (13) and the lower filter screen (11) on the multi-stage filtering structure finally flows out through the lower discharge pipe (9).
