(Summary description) 1. The bed surface division of the shaker The bed surface is divided into concentrate area, middle mining area, tailings area and sludge area. Generally, the width of the mud area is 0.9~1.4m. The ore flow in the tailings area should be stable, and there should be no rapids or ravines. The thickness of the ore bed must be appropriate and must be covered with water. The tailings area can be controlled by adjusting the feed concentration and the sand hole of the feed trough. The middle mining area is the division of the middle mining area, which is mainly controlled by adjusting the scouring water and the lateral slope. The beneficiation area requires the separation zone of each specific gravity mineral to be obvious. In order to form a stable and obvious boundary between the beneficiation area and the primary selection area, the area is controlled by adjusting the scouring water and the lateral slope. 2, the horizontal and vertical slope of the floor of the shaker When the equipment is installed, the longitudinal slope is determined, the coarse sand area is longitudinally inclined 1~2, the fine sand area is 0.5~1.0, and the ore mud area has basically no slope. The bed surface is inclined by 1.5~5 from the feeding end to the opposite side. In actual operation of the shaker, the vertical and horizontal slope of the shaker surface must be accurately controlled. Generally, when the mineral particles are relatively coarse, the lateral slope of the shaker floor should be appropriately increased. On the contrary, if the mineral particles are very fine, the slope of the ground needs to be lowered. Generally, the transverse slope ranges of coarse sand area, fine sand area and sludge area are 2.5~4.5, 1.5~3.5, and 1~2 respectively. 3, feed size The particle size of the ore must be appropriate. The upper limit of the input particle size is 2~3mm, and the lower limit is 0.037mm. Generally speaking, classification in advance ensures uniform particle size at all levels, but in order to ensure that the particle size at all levels of the shaker is uniform and the particle size is within the appropriate range, it is necessary to observe the ore belt in the concentrate belt and check the tailings through ore washing. 4, the amount of ore The size of the ore volume is related to the size of the raw material. When the ore grains are coarse, the required amount of ore feed becomes larger. However, if the amount of ore is too much, it will cause banding problems. In this case, it is necessary to move the concentrate cut-out board to increase the horizontal slope of the flushing water and the shaker surface. It should be noted that once an accurate feeding amount is found, it is necessary to continuously ensure the feeding process to maintain uniformity. 5, the concentration of the ore In the screening process, it is necessary to ensure the proper concentration of the ore. Generally speaking, the feed concentration of coarse and fine-grained minerals is 20% ~ 30% and 15% ~ 25% respectively. When there is a groove problem on the rocking bed, the ore concentration can be appropriately increased to adjust; on the contrary, when sand hills appear, the ore concentration needs to be reduced at this time. The concentration of ore can be controlled by adjusting the amount of water supply. 6. Washing water Flushing water includes mineral water and flushing water. When operating the shaker, when the concentrate belt becomes narrow and the concentrate rushes into the middle ore, the amount of flushing water needs to be reduced; on the contrary, when the floor of the shaker is exposed to anhydrous film, the amount of flushing water needs to be increased appropriately. To control the amount of washing water, it is necessary to carefully observe the slurry flow rate and the narrow width of the concentrate belt.
