Capacity of a shaking table is in the range between 0.5 tons per hour and approx. 1.5–2 tons per hour depending on the particle size processed. Therefore, it is usually a standard in the industry to install tens of shaking tables in series or parallel in order to process excessive tonnages, especially in chromite processing.

Parameter variations are relatively common during the test as the specimen changes in response to the unleashed inertial forces. The nonlinear regime of specimens also plays an important role in such parametric changes. (iv) MCS can cope with nonlinear dynamics, which shaking tables exhibit over their range of operation.
