Jul 07, 2021 an earthquake is a weak to violent shaking of the ground produced by the sudden movement of rock materials below the earth’s surface.. the earthquakes originate in tectonic plate boundary. the focus is point inside the earth where the earthquake started, sometimes called the hypocenter, and the point on the surface of the earth directly above the focus is called the epicenter.Introduction shaking table has been widely applied in many industries, which can conduct different working modes such as rough separation, fine separation and scavenging. it is suitable for separating gold, silver, tungsten, zinc, iron, manganese, lead, coal and other metal or heavy metal materials. shaking table is suitable for 2-0.5mm coarse shaking table.
Introduction. gold shaker table is used as a gravity separation device to sort fine materials. the shaking table separation depends on the combined effect of mechanical asymmetric reciprocating motion and thin water layer on the sloping table surface, so that ore particles on the table get loose and move to different layers and zones, and then the minerals are separated according to different shaking table.
