s1, preparation: starting the driving transmission assembly and simultaneously driving the crushing assembly and the stirring assembly to move;

s2, feeding: raw materials are led into the crushing chamber 3 from the feeding assembly 4, the raw materials are in contact with the crushing assembly, the agglomerated raw materials are crushed by the crushing assembly and then enter the mixing chamber 101, and normal raw materials can directly pass through the crushing assembly and enter the mixing chamber 101;

s3, stirring: the raw materials enter the mixing chamber 101 and then contact with the stirring assembly, the stirring shaft 601 drives the stirring blades 602 to move to stir and mix the raw materials, and the arc-shaped stirring plate 603 is driven by the stirring shaft 601 to stir and grind the raw materials on the bottom surface of the mixing chamber 101, so that the mixing effect is improved;

s4, discharging: after the mixing of the raw materials is completed, the discharge assembly is adjusted to discharge the mixture in the mixing chamber 101.

In the preparation stage, the crushing assembly and the stirring assembly are started, so that the crushing assembly and the stirring assembly can be preheated, and the agglomerated raw materials and the stirred raw materials can be crushed better in the follow-up process; on the other hand, the mixing chamber 101 is a sealed chamber, and a part of heat remains in the mixing chamber 101 after the stirring assembly is started, which is beneficial to mixing of the raw materials. When feeding, because the feeding assembly 4 can collect the raw materials, the required amount can be introduced at one time when the raw materials are introduced, and the raw materials do not need to be gathered. During the ejection of compact, can manually adjust ejection of compact subassembly, can design into the lateral wall of organism 1 transparent under this circumstances, make operating personnel can observe the mixture state in mixing chamber 101 in real time, also can set up detection device in mixing chamber 101, detection device is to outside transmission signal after the mixture mixes the completion, will design into electric control with ejection of compact subassembly's regulation mode this moment, and the opportunity of adjusting is controlled by detection device.

Through above-mentioned technical scheme, the raw materials can be broken better before mixing, can be by intensive mixing when mixing, and the mixture of exporting like this is more meticulous, the coating of the higher quality that can obtain finally.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
