VIBRATION DEVICE FOR GRINDING BULK MATERIALS Russian patent published in 2019 - IPC B02C17/14 B02C19/16 

FIELD: disintegrators and crushing devices.

SUBSTANCE: invention relates to the equipment for grinding bulk materials and can be used in the food, construction, chemical and metallurgical industries as well as in agricultural production. Device contains a drive, a drum with loading and unloading pins. Drum is made as multifaceted prism installed obliquely at an acute angle α relative to the horizontal axis of rotation with flat edges around its perimeter and with flat butt cheeks of polygonal shape, placed at different sharp angles β and ψ to the axis of rotation of the prism and to each other at an acute angle ϕ. Longest axes of the end cheeks of the polygonal shape are rotated along the axis of rotation of the drum relative to each other at an acute angle ω. Drive drum with loading and unloading pins attached to the frame, which is elastically mounted on the frame.

EFFECT: ensured technological expansion, increased productivity.
