Abstract

It was made new modification of device for allows increasing recovery, to increase productivity and to lower size of concentrated particles. The device has a deck executed as a circle, which divides into two sectors; each sector has circular rifles with progressively growing height from the centre to periphery of a deck. The table is equipped with the high-frequency step-by-step engine ensuring continuous rotation of a table and submission counter impulses for shear of particles in a direction, opposite to rotation of a table. The quantity of angle sectors can be various. Testing of prototype of a table has confirmed an opportunity of increase of recovery, decrease size of extracted dense minerals and increase of throughput.
