VIBRATIONAL MILL Russian patent published in 2017 - IPC B02C19/16 B02C17/00 

FIELD: machine engineering.

SUBSTANCE: grinding mill comprises a cylindrical grinding chamber 1, filled with grinding bodies 2, installed with elastic elements 3 and 4 on a stationary base 5. The grinding chamber 1 is rigidly connected to the side unbalanced vibrators 6 and 7, which are located on its diametrically opposite sides in a plane transverse to the symmetry of the grinding chamber. The unbalanced vibro drives 6, 7 and 8 consist of shafts with drives, designed to independently change the angular velocity and direction of rotation, and unbalances, the mass of which can vary. The axes of rotation A and D of the lateral unbalanced vibration drives 6 and 7 are perpendicular to the transverse symmetry plane of the grinding chamber. In the proposed solution, the lateral unbalanced vibro drives 6 and 7 are offset in different directions relative to the horizontal axis B passing through the center of gravity C of the grinding chamber. At the bottom of the grinding chamber is an additional unbalanced vibro drive 8 with the possibility of independent change of angular velocity and the direction of rotation, the axis of rotation E which is located on the vertical axis F passing through the center of gravity C of the grinding chamber.

EFFECT: in mill it is provided a degree of grinding of materials and intensification of their movement.
