AUTOMATIC CRUSHER AND METHOD OF GRINDING IN IT Russian patent published in 2021 - IPC B02C2/00 A47J42/00 

FIELD: crushers.

SUBSTANCE: group of inventions relates to an automatic crusher for grinding and a method of grinding in such a crusher. The automatic crusher contains a control structure and at least one material container assembly. The control structure comprises a drive unit and a connecting structure connected to the drive unit. The material container assembly comprises a material container case, a crushing head rigidly connected to the material container case, and a crushing sleeve connected to the crushing head with a possibility of rotation. In the material container case, a groove is made, which contacts with the connecting structure. The crushing head is inserted into the crushing sleeve, and the crushing head and the crushing sleeve determine between themselves the material compartment for placing the material. The drive unit rotates the material container case by means of a connecting structure. The crushing head is rotated by the container case and moves relatively to the crushing sleeve so that the material between the crushing head and the crushing sleeve is crushed into powder. The grinding method includes a grinding step in which the drive unit rotates the material container case by means of a connecting structure, and the material container case rotates the crushing head, which moves relatively to the crushing sleeve. The material is crushed by moving the crushing head relatively to the crushing sleeve. To grind the second material, the material container assembly is disconnected from the drive assembly and replaced with another material container assembly, after which the grinding stage is resumed.

EFFECT: automatic crusher eliminates the mixing of various crushed materials.
