DEVICE FOR IMPACT-CENTRIFUGAL CRUSHING AND CHIPPING Russian patent published in 2009 - IPC B02C13/14 

FIELD: mechanical engineering.

SUBSTANCE: invention refers to mechanical engineering, in particular to impact-centrifugal crushes and mills and can be applied in construction, mining-concentration, chemical, metal and other industries for crushing and chipping various metallic and nonmetallic bulk materials. Device for impact-centrifugal crushing and chipping includes body, branch pipe for raw material feeding located at the top of the body, branch pipe for final product output located at the bottom of the body, beating elements mounted on side wall of the body, accelerator located on vertical shaft in the body, raw material distribution tool, coaxially fixed accelerator rotation axes and accelerator drive. Raw material distribution tool is made in the form of disk with circular bead on its peripheral portion and rigidly attached to the body or the branch pipe for raw material feeding.

EFFECT: invention allows to increase durability of raw material distribution tool due to significant reducing abrasive wear caused by raw material action.
