After the material enters the pulverizing chamber of the pulverizing assembly, it is crushed and sheared by the grinding wheel that moves in a circular motion along the grinding rail. The pulverized material passes through the negative pressure airflow caused by the fan and passes through the grading wheel to achieve particle size classification, and then is taken out of the pulverizing chamber. After being processed by the cyclone separator and the dust collector, the overall pulverization and impurity removal and filtration work can be completed.

[0021] 2. The ultra-low temperature ultra-fine pulverizer can drive the grinding wheel to rotate through the main shaft and the grinding wheel bracket by starting the grading motor. After the grinding wheel rotates, it can cooperate with the grinding rail to exert horizontal shear force on the material, which can cut and cut the fibers in the material. At the same time, it can also apply rolling force from the vertical direction to crush the material to an extremely high fineness. The installation shaft and positioning bolts can be used to facilitate the removal of the grinding wheel for maintenance. The crushing chamber cover can be opened to facilitate feeding and maintenance of the structure of the inner cavity of the crushing chamber.

[0022] 3. The ultra-low temperature ultra-fine pulverizer can classify the pulverized materials through the grading wheel, so that the materials that do not meet the size can be placed in the inner cavity of the pulverizing chamber for continuous pulverization until they meet the size, so that the pulverized particle size of the materials can be finer and more uniform, which can effectively solve the problem of uneven particle size of the materials.

[0023] 4. The ultra-low temperature ultrafine pulverizer can ensure that the material is pulverized in a low temperature state in the inner cavity of the pulverizing chamber by setting up an ultra-low temperature refrigerator, thereby ensuring that the activity of the organism is not destroyed and making it difficult for heat-sensitive materials to soften and deteriorate.

[0037] The ultrafine grinding of dry materials is achieved by vertical grinding and horizontal shearing. The device is composed of a PLC electrical control cabinet 1, a grinding component 2, a fan 11, a cyclone separator 12, a dust collector 13, an ultra-low temperature refrigerator 14, a first collecting box 15 and a second collecting box 16. After the material enters the grinding chamber 10 of the grinding component 2, it is crushed and sheared by the grinding wheel 8 that moves in a circle along the grinding rail 22 to achieve crushing. The crushed material passes through the negative pressure airflow caused by the fan 11 and passes through the grading wheel 5 to achieve particle size classification.

By means of the ultra-low temperature refrigerator 14, it can be ensured that the material is crushed in the inner cavity of the crushing chamber 10 at a low temperature, thereby ensuring that the activity of the organism is not destroyed and making it difficult for the heat-sensitive material to soften and deteriorate.

After the grinding wheel 8 rotates, its bottom will rotate on the top of the grinding rail 22, thereby realizing ultra-fine pulverization of dry materials based on vertical grinding and horizontal shearing. The fan 11 is started, and the grinding wheel 8 is rotated.

When the coarser material passes through the grading wheel 5, it will be isolated so that it can be placed back in the inner cavity of the crushing chamber 10 to continue crushing. The remaining material enters the inner cavity of the cyclone separator 12 for separation and processing. The separated impurities fall into the inner cavity of the first collecting box 15. The dust collector 13 is started, so that the hose 17 can draw the remaining material in the inner cavity of the cyclone separator 12 into the inner cavity of the dust collector 13 for dust removal. After dust removal, the finished material falls into the second collecting box 16.
