The sand gold shaking table is to feed the sand gold ore particles from the feeding chute at the upper corner of the bed surface, and at the same time supply the transverse rinsing water from the feeding chute, so the sand gold ore particles are stratified according to the specific gravity and particle size under the action of gravity, transverse running water impulse, inertia and friction generated by reciprocating asymmetric movement of the bed surface, and make longitudinal movement along the bed surface and transverse movement along the tilted bed surface. Ore particles with different specific gravity and particle size gradually fan out along their respective directions of movement, and are discharged from different zones at the concentrate end and tailings side respectively, and are finally divided into concentrate, medium ore and tailings.

In order to ensure the efficiency of its production, it is recommended to follow the following points:

　　1, according to the change of incoming ore, adjust the washing water volume and lateral slope in time to keep the concentrate belt stable and in a straight line.

　　2、Frequently clean the sand trough and ore discharge holes of the shaking table to keep it unobstructed and even under the sand, and the bed surface does not produce pulling ditch rapids.

　　3、After each overhaul, take the initiative to check and adjust the stroke and stroke times to ensure that they meet the technical requirements.

　　4, the inspection before driving: before driving, carefully check whether the safety cover is complete, rocking the head of the bed with or without oil leakage, lubricating oil road is normal. Separate mud bucket, separator box of each channel, groove is smooth, there is no debris blockage, equipment, electrical is normal.

　　5, sand and gold extraction equipment shaking bed normal operation to tour the inspection:

　　a, the motor, the temperature of the bed oil bin, the ringing sound is normal, whether the foot bolt is solid, whether the bed jumps, whether the oil chain in the bed oil bin is rotating.

　　b, whether the flow is wrong, whether the flow direction is correct, whether the pipeline, trough has through leakage.

　　c, the separation of mud bucket, separator box overflow tank, grading box sand bar gap is smooth, and timely removal of bed dirt.
