FIELD: process engineering. ^ SUBSTANCE: invention relates to production of abrasive diamond grains and powders, particularly, to units intended for grading them to sizes. Proposed device comprises vibrating table inclined to lengthwise axis, plate with composite flexible elements that form the angle with work table lengthwise axis in horizontal plane, and intake cells. Work table is installed inclined relative to crosswise axis, while composite flexible elements form the angle with work table lengthwise axis in horizontal plane as well as dihedral angle exceeding 90, in whatever cross section perpendicular to grain path along flexible elements. The distance from work table to flexible elements equals that from flexible elements to intake cells measured in the table plane. ^ EFFECT: higher quality and efficiency. ^ 3 dwg |
