Abstract: In order to improve the control bandwidth of the electro-hydraulic servo shaking table, a three-state control strategy based on state space analysis is proposed in this paper. First, the working principle of electro-hydraulic servo shaking table is introduced. According to the theory of electro-hydraulic servo system, four equations describing the …

Working Principle. The ore dressing shake table can make the ore particles move in different directions according to their density and particle size, and fan out along the diagonal line from the ore feeding trough, and discharge along the edge of the bed surface in turn. The ore discharge line is very long and can accurately produce a variety ...

Traditional operation control of shaking table mainly relies on the operators to observe the ore belt of and then determine the operation state through the appearance characteristic information such as the shape and color of the ore belt. The feed water, slope angle, stroke, stroke rate and other operating parameters are adjusted accordingly.

The table is supported by the frame or lifted by the frame. The table of the shaking table is inclined, 1.5-5 degrees in the lateral direction from the feed end to the opposite side, so that the water flow from the feed trough and rinse trough to form a thin layer of inclined water flow on the table. There is a feeding trough on the upper right ...

What is Shaking Table. Shaking tables, also known as wet tables, consist of a sloping deck with a riffled surface. A motor drives a small arm that shakes the table along its length, parallel to the riffle and rifle pattern. This longitudinal shaking motion consists of a slow forward stroke followed by rapid return strike.

Principle of Shaking Table Beneficiation. While the ore particles are stratified between the beds, they also move in different directions along the bed. In the beginning, the mineral particles are relatively static on the bed surface. To make the mineral particles move relative to the bed surface, only when the inertial force of the mineral ...

. There are many factors affecting the work of the shaking table, among which the main stroke, the number of strokes, the concentration of ore feeding, the amount of ore feeding, the flushing water for the ore body, the lateral slope of the bed surface, and the nature of the ore feeding. (1) Stroke and stroke times.

1.3 Operation of Shaking Tables. Shaking table is a mechanical device that is used to test any structures under seismic or other types of dynamic loading such as step load, sinusoidal varying force, or random load. If the shaking table is designed primarily to test civil structure under seismic loading, then it is also called earthquake simulator.
