The beneficiation process of the beneficiation shaker is carried out on the inclined bed surface with spokes, and the ore particles are sent from the ore feeding tank at the upper corner of the bed surface, and the transverse flushing water is supplied by the water feeding tank. Therefore, the ore particles are layered according to specific gravity and particle size under the action of gravity, transverse water impact, inertia and friction caused by the reciprocating asymmetric movement of the bed surface, And make longitudinal movement along the bed surface and transverse movement along the inclined bed surface. Therefore, ore particles with different specific gravity and particle size gradually flow down in a sector from side a to side B along their respective movement direction, discharge from different areas at the concentrate end and tailings side respectively, and then be divided into concentrate, medium ore and tailings. In order to better prolong the service time of the equipment, the equipment needs to be maintained. So what should we do?

1. If the moving parts at the head of the beneficiation shaker are worn too much, they should be replaced. Ore trough and water tank shall be firm to prevent loosening.

2. The bed runout can be removed by adjusting the tightness of the spring, adjusting the improper position of the four support points, correcting the improperly matched stroke stroke system, and correcting the deviation at the connection of the pull rod.

3. Adjust the sand valve and rising water of the grading box in front of the shaker operation or adjust the ore separator to control the ore feeding amount and ore feeding concentration. Adjust the ore feeding and add water to adjust the ore feeding concentration.

4. Adjust the slope adjustment hand wheel to change the cross slope of the bed surface; Adjust the size of flushing water and the position of water distribution valve, change the flow rate and distribution of flushing water film, obtain neat and carry out concentrate belt.

5. Check whether the connecting screw is loose, whether the position of the pull rod is appropriate, whether the spring is too loose or broken, whether the shaking or sliding surface is in good contact, and whether the bed surface is in contact with non shaking parts. The cause of the abnormal sound can be found and eliminated.

6. During ore stoppage, the bed surface shall be flushed to prevent impurities from oxidizing and scaling the composite crusher. If there is scaling, it shall be removed.
