  • Brief Introductions for Mineral Shaking Table 

    Gold Shaking Table can carry out ore concentration operation independently and also can operate in conjunction with jig, screw separator, centrifugal separator and other equipment. The product is made by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

    Shaking Table is to make separations based on the difference of specific gravity of feed materials, reciprocating asymmetrical movement and the stratification performance of the inclined table surface in the lateral water flow with obvious zone of the minerals with different specific gravities on the table, high quality of concentrates produced, convenient operation and adjustment and other features.The table surface is constructed of ore sand or slime and is made up of glass fibre reinforced plastic or aluminum alloy.

    Glass steel shaking tables are effective gravity separation equipment which can  be used for different operation such as rough selection, elaborate selection  and scavenging for large, medium and small-sized factories and applies to the  sorting of nonferrous metal, ferrous metal, rare and precious metal, gold and  nonmetallic ores of fine grains. Such shaking tables are divided into ore sand  tables and ore slime tables. Ore  sand tables apply to the sorting of coarse ores and ore slime tables apply to  the sorting of fine ores.

     

     

    Structure and Working Principle of Mineral Shaking Table

    The working principle of shaking table is to use the combined  action of the specific gravity difference of sorted minerals, alternating  movement of bed surface, and transverse oblique water flow and riffle (or notch  groove), to allow loose layering of ores on the bed surface and fan-shaped  zoning. Then different products can be produced.

    Gold shaking table is composed of three parts, i.e. head of shaking  table, surface of shaking table, as well as bearing and adjusting gradient.

    1. Head of shaking table:

    This is eccentric connecting-rod type  mechanism. The motor drives the eccentric shafts to rotate and the connecting  rod to move up and down. When the connecting rod pushes down the toggle plate  compression spring, the pull rod drives the table surface to move in the  direction of table head. When the connecting rod pushes it upward, it, through  the spring tension, drives the table surface to move in the opposite direction.  When they are linked, the rotating motion of eccentric shaft is changed into  horizontal alternating differential motion of table surface.

    2. Table surface:

    It is mainly composed of vibrating roof, steel  skeleton, glass fiber reinforced plastics and wear-proof surface, feed water  tank, feed chute, and draw bar. The table surface adopts steel skeleton FRP  composite structure. That is, glass fiber reinforced plastics are pasted on  steel skeleton to form a solid glassfiber reinforced plastic surface. Its above  uses abrasion-proof materials to make surface and riffle (notch groove).

    3. Bearing and Adjusting Gradient Mechanism:

    The bearing and  adjusting gradient mechanism is mainly composed of shaking support plate,  adjusting seat board, saddle seat, and adjusting screw rod. The shaking support  plate enables the table surface to make arc forward and backward alternating  movement on vertical plane. The shaking support plate and shaking box are fixed  on the adjusting seat board with gripping channel steel. When hand wheel  regulating screw rod is used to get the adjusting seat board to rotate on the  saddle seat, the Transverse gradient of table surface can be adjusted.
