Shaking Table Separation
Shaking table separation is the gravity concentra-tion process in which the combined action of the asymmetric reciprocating motion of the table and the water flow on the thin inclined layer separates the mineral particles according to their densities on a wide inclined table. Shaking table separation is suitable for separation of ne particle ...
Vibratory Tables Selection Guide: Types, Features, …
Vibratory tables are table assemblies that are shaken by a vibrator and it is mainly used for fatigue testing, concrete casting, breaking apart, or compaction of media or packaging. Vibratory tables are also known as vibrating tables or shakeout tables. The vibrations of vibratory tables are often imparted by means of off-balance masses ...
Shaking Table Motions
A shaft and cam arrangement at one end of the table served as the actuating mechanism and imparted to the table an endwise, back-and-forth, swinging motion. A shaking block was fixed in the proper position at the shaft end, so that the table would strike against it at the end of each backward swing. The hanger rods or stirrups were so …

Gravity Separation of Zinc Mine Tailing Using Shaking Table …
Analyses in ICP-OES showed that the concentrate material had 40.4% of iron, while in raw material, it was 7%. Therefore, gravity separation using shaking table is seen as an interesting alternative since it reduces the zinc mine tailing, requires less energy and makes possible the material return to process in the steel industry.
An overview of control schemes for hydraulic shaking tables
Shaking table testing is a common experimental method in earthquake engineering for performance assessment of structures subjected to dynamic excitations. As most shaking tables are driven by servo hydraulic actuators to meet the potentially significant force stroke demand, the review is restricted to hydraulic shaking tables.
