The beneficiation process of ore dressing shaking table is carried out on the inclined bed with compound bars, the ore particles are fed into the feeding trough from the upper corner of the bed, and at the same time the transverse flushing water is supplied from the feeding trough, so the ore particles are stratified according to the specific gravity and particle size under the action of gravity, transverse water impact, inertia and friction generated by reciprocating asymmetric movement of the bed and move along the bed in longitudinal direction and along the inclined bed in transverse direction. Therefore, the ore particles with different specific gravity and particle size gradually flow down in a fan shape from side A to side B along their respective movement directions, and are discharged from different zones at the concentrate end and tailing side respectively, and are finally divided into concentrate, middle ore and tailing. 　The following introduction 6s shaking table use to pay attention to do what maintenance work? 　　1, the bed head moving parts should be spear replaced when the wear and tear is too large. Ore trough, water trough should be firm to prevent loosening. 　　2, adjust the spring tightness, adjust the improper position of the four support points, correct the matching improper stroke stroke system, correct the tie rod connection at the bias section, you can clear the bed jumping. 　　3, adjust the shaking table work in front of the grading box sand valve and rising water or adjust the mineral separator to control the amount of ore and ore concentration, adjust the ore replenishment water can be adjusted to the concentration of ore. 　　4、Adjust the slope handwheel to change the lateral slope of the bed; adjust the size of the flushing water and the position of the water valve to change the flow rate and distribution of the flushing water film, to get neat, carry out the concentrate belt. 　　5、Check whether the connecting screws are loose, whether the position of the tie rod is appropriate, whether the spring is too loose or dismantled, whether the shaking or sliding surface is in good contact, whether the bed surface is in contact with the non-shaking parts, you can find the cause of the abnormal rattling sound and eliminate it. 　　6, stopping the mine, the bed should be flushed clean, so as to avoid impurities oxidation scaling compound crusher. If there is scaling, it should be added to remove.
