The unit for gravity concentration of fine particles
- Saint Petersburg State Mining Institute (Technical University)
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.
