The material is sent into the crushing chamber between the body of the dust suction crusher and the guide ring. Under the impact of the high-speed rotating blade in the crushing chamber, the material is thrown to the ring gear fixed on the body, causing impact, shearing, and The material, the blade, and the ring gear collide, friction, and shear alternately to crush. After the crushed material, under the pulling force of the negative pressure airflow, the small powder particles overcome their own weight, and follow the airflow over the diversion ring and enter the classification chamber. The grading impeller of the dust suction grinder is composed of blades. The high-speed rotating blades produce centrifugal force opposite to the negative pressure. The powder particles sinking into the blade channel are simultaneously subjected to the centripetal force of the negative pressure airflow, the weight of the powder particles and the centrifugal force generated by the impeller. The particles larger than the critical diameter are thrown back to the crushing chamber to continue to be crushed due to their large mass. The particles smaller than the critical diameter enter the cyclone collector through the powder discharge pipe and are discharged through the discharge valve.
It can be applied to the crushing process of the aquatic feed industry, and the dust suction crusher has the advantages of easy cleaning and no residue, and can effectively prevent the mutual contamination of materials. In the crushing of aquatic feeds, the requirements for the fineness of the particles are often very high, so the ultra-fine crushing technology can achieve the maximum crushing effect and make the crushing more uniform. The main feature is that it will not generate a lot of heat during the production process, resulting in product fragments. For bonding, the dust suction pulverizer uses the needle tip between the movable sprocket and the fixed sprocket to operate at high speed on the wheat awns, so that the pulverized objects are crushed by the impact, friction of the sprocket and the collision of the materials with each other. The crushed material can be directly discharged from the mill cavity and come out through the discharge port. After crushing, the material is put into a cloth bag and collected. The crushed material is collected in the bag, and the air comes out of the small holes of the cloth bag, so the fine powder will not be discharged. Non-polluting results.
