The ore feeding volume is also an important factor in the operation of the shaking table. If the ore feeding volume is constant, the ore feeding concentration is too low and the pulp volume increases, which will cause the beneficiation recovery rate to decrease. If the amount of ore to be fed is certain, and the concentration of ore to be fed ...
