In practical application, the ground ultrafine powder is poured into the screening tank 201, the stirring motor 202 is started, the breaking rod 204 breaks up the materials, the broken ultrafine powder is screened to the bottom of the screening tank 201 by matching the scraper 205 with the bristles 2051, the materials enter the kneading tank 301 through the feeding pipe 208, the auxiliary motor 303 and the kneading motor 304 are started to enable the auxiliary motor 303 to rotate clockwise, the kneading motor 304 rotates anticlockwise, the second electromagnetic valve 306 is opened to add water into the kneading tank 301, the first helical blade 310 on the second rotating rod 312 stirs the materials at the bottom of the kneading tank 301, the first helical blade 310 on the third rotating rod 311 extrudes the materials above to the lower part of the kneading tank 301, the kneading and stirring are carried out in a reciprocating manner, meanwhile, the friction and stirring between the rising materials and the materials pressing down can be continued, the kneading efficiency and the kneading quality are effectively improved, so that the materials are quickly and fully kneaded in a short time, after the kneading is finished, the auxiliary motor 303 is closed, the kneading motor 304 is controlled to rotate clockwise, the first electromagnetic valve 309 is opened, and the kneaded materials are led out through the discharge pipe 308.

The present invention can be easily implemented by those skilled in the art from the above detailed description. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the basis of the disclosed embodiments, a person skilled in the art can combine different technical features at will, thereby implementing different technical solutions.
