Shaking table is one of the major gravity ore dressing machines, in some aspect it is the most important gravity ore dressing machine. It was designed to concentrate the fine-grinded or micro-grinded rare metal & precious material.

The shaking table separate the mineral granular based on the gravity differences between the different materials inside the pulp. When the pulp reached the table surface from the feeding channel, the granular in it will be effected by the gravity force, water flow force, the inertial force and friction force which comes from the reciprocating movement of the table surface, under the effect of these four forces, the granular inside the pulp will be classified and moved to the different direction: the high density one will go front and drop from the concentration end, the gangue will go to the tailing side, and the middles will be re-concentrated on the shaking table.
