APPARATUS FOR FINISHING-CLEANING AND HARDENING PROCESSING Russian patent published in 2019 - IPC B24B31/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in finishing cleaning of parts in free granulated medium. Proposed plant comprises drums with drive elastically installed on said bed with loading and unloading means and composed of cylinder with ellipsoidal end walls. Inner perimeter of the drum has pockets of curvilinear shape, and along the outer perimeter there are alternating ledges of curvilinear shape. Elliptical elliptical flat end walls are parallel to each other, arranged inclined at an angle to the drum horizontal axis, are turned relative to each other by an angle β and have perimeter generatrices in the form of alternating projections of curved shape, corresponding to shape and dimensions of said drum projections. Latter is made with loading and unloading journals of conical shape with coils of rectangular cross-section rigidly fixed on inner diameter.

EFFECT: as a result, the technological capabilities of the installation are expanded and the processing efficiency is increased.
