Apparatus and method for the production of fine heavy particle fine particles of high density ( 5 g / cm³) in facilities for the extraction of sands and gravels

摘要

For secondary production of heavy particle fine particles, the water-sand mixture is passed through the separator. In this process, the light particles are separated from the heavy particle fine particles by the combination of gravity, gradient and the particular shape of the tissues. The invention causes a better fishing behavior and a higher accumulation of heavy minerals. This is achieved by flushing light particles upwards and the heavier particles downwards through the throughflow openings of the individual tissues. The particles settle in the tissues.
