BTMA–How much do you know about the shaking table?

Shaking Table introduction


In gravity separation, gold shaking table (gravity separation table) is the most widely used and most efficient fine-grained ore separation equipment. Shaking Table beneficiation is not just used as an independent beneficiation method.




Nevertheless, it is often used in combination with mineral processing equipment such as jigs, flotation, centrifugal separators, magnetic separations, spiral classifiers, and spiral chutes.


The Shaking Table is composed of 8 parts: bed head, motor, slope regulator, bed surface, mining tank, water tank, rifling rod and lubrication system. The longitudinal reciprocating motion of the bed surface is realized by the crank connecting rod transmission mechanism.


Working principle of Shaking Table


The gold Shaking Table is one of the oldest gravity separators in the beneficiation industry, which can process 0-2mm minerals and coal.


Shaking Tables are rectangular tables with a corrugated deck on which a layer of water flows. A mechanical transmission moves the table along the long axis perpendicular to the flow of water. The water carries the feed particles in the slurry through the rifling in a fluid film. This causes fine, high-density particles to fall into the riverbed behind, as coarse, low-density particles are carried in the fast-moving film.


The action of the workbench is such that the particles move with the workbench towards the discharge end until the end of the workbench travel, at which time the workbench moves back rapidly, and the momentum of the particles pushes them to still move forward.


The production capacity of the gold mining Shaking Table is about 0.5 t/h, 1.5 ~ 2tph depends on the process granularity. Chromite processing plants generally use dozens of Shaking Tables installed in series or in parallel to process excess tons of ore. Therefore, the required installation space, the difficulty of equipment control due to the increase in the number of installations, and the need for a more automated process bring new challenges to process design).
