DUAL-PURPOSE CRUSHER AND ITS OPERATION METHOD Russian patent published in 2022 - IPC B02C2/00 A47J42/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to crushing devices. The crusher contains a material container assembly having a crushing head rigidly connected to the body of the material container, and a crushing sleeve connected with the possibility of rotation with the crushing head. The crushing head enters the crushing sleeve and defines with the crushing sleeve a material compartment for placing the material. The crusher also contains a connecting structure designed to be connected to an external power supply unit located at the upper end of the material container housing. The material container housing is made with the possibility of rotation and drive in rotation of the crushing head. At the same time, during manual crushing, the crushing sleeve moves relative to the crushing head so that the material is crushed between the crushing head and the crushing sleeve. During automatic crushing, the body of the material container is connected to the external power unit by means of a connecting structure and is rotated by the external power unit so that the crushing head is rotated.

EFFECT: crusher provides the possibility of manual and automatic grinding.
