The feed concentration, feed quantity, and the dry ore quantity and feed concentration of the ore body to the shaking table determine the pulp volume. The feed concentration and feed volume have a great influence on the separation of the shaking table. The feed concentration is too large, the pulp turnover is large, the fluidity is bad, and many heavy minerals can not be layered and zoned; If the concentration is too thin, it will not only reduce the productivity of the shaker, but also cause the loss of fine concentrate to the tailings. The appropriate pulp concentration should ensure that the pulp has sufficient fluidity and the stratification and zoning of ore particles on the bed surface. The ore feeding concentration of shaking table is generally 15% - 30%.

The feed volume is also an important factor in the operation of beneficiation shaker. If the feed concentration is too low and the pulp volume increases when the feed volume is certain, the beneficiation recovery will decrease. If the ore feeding amount is certain and the ore feeding concentration is too large, it will also reduce the beneficiation recovery. The size of ore feeding is also determined according to the particle size of the treated ore.
