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. 2. Main technical parameters

Shaking tables are one of the oldest gravity separators in the mineral processing industry, capable of handling minerals and coal of 0-2mm. Shaking tables are rectangular-shaped tables with riffled decks across which a film of water flows. The mechanical drive imparts motion along the long axis of the table, perpendicular to the flow of the water.

Shaking tables provide one means of obtaining data from physical models of geotechnical systems under simulated earthquake loading. While there may be challenges in ensuring exact scaling of all aspects of a geotechnical system between prototype and model, the large size of the shaking table models does give a good basis for validation of numerical modelling strategies.

3.2. Similitude relationship. The important step in the test is defining the similitude relationship between the test model and the prototype. Considering the dimension and bearing capacity of the shaking tables, it is difficult to make all the model parameters to satisfy the corresponding similarity ratios simultaneously for both the model structure and model soil.

Jul 10, 2019· In deciding on these parameters, far-source (or "ordinary") and near-source earthquake ground motions to be reproduced by the shake table were considered. A maximum horizontal peak ground and peak table acceleration of just over 1g was selected based on the upper bound for the vast majority of recorded ground motion records.
