Spiral classifier for gravity separation

Gravity separation of shot particles is of fundamental importance for peening. From a commercial viewpoint it is the basis of several methods for separating acceptable from unacceptable shot shapes i.e. classification. The commonest such method is probably spiral gravity separation. This method has a long and successful history

    The motion of the spiral creates Pool Hindered Settling in the bottom pool area, where the agitation of the water hinder the fines from settling to the bottom, but the coarser particles do settle and are carried up the slope by the revolving spiral, to the discharge, located at the top of the classifier. Then gravity flow or pumps are used to

    The Gravity Separation Methods Used To Process Gold?

    Sep 17, 2019 Gravity separation is one of the common methods for gold extraction, which uses different specific gravity of materials and different settlement velocity in the medium to carry out stratified separation. Generally, when gold mostly exists in the form of monomer natural gold, the density difference between gold and gangue is large, it is more effective and economical for gold separation
