Operation of Shaking Tables. Adjustments are provided in all tables for the amount of wash water, the cross tilt, the speed, and the length of the stroke. The speed of the table ranges usually from 180 to 270 strokes per minute, and the strokes are from 1/2″ to 1 1/2″ long. Generally speaking, a gold shaker table will see the adjustments as ...

Air tables use a shaking motion similar to that of shaking tables, but instead of water, air is used to separate heavy minerals. The table deck is covered with a porous material and air is blown up through the deck from a chamber underneath. The chamber equalizes the pressure from the compressor and thus ensures an even flow of air over …

Principle and Operation of the Vibrating Screen. In the case of a vibrating screen, the vibrations are given to the screen to effect the separation of solid particles into two size fractions. Vibrations given keep the solid particles moving. Proper selected frequency and amplitude keep the capacity constant.
