Once Hand Arm Vibration Syndrome has been onset it is impossible to cure. It is therefore essential that individuals know the risks and employers take the preventative
Read OnShaking 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.
