The intermittent supply and exhaust of Jigging Air into the Air Chamber beneath the Jigging Bed is controlled electro – pneumatically through a Piston Valve System. The frequency of air intake and exhaust Piston Type Air Valve can be controlled through PLC Programme based on the characteristics of Raw Coal and Mineral Ore.
As the feed advances along with the Jig Pulsation of water, it gets stratified in Density Layers. The heavy fraction of the stratified feed material is sensed by Hydrodynamically designed Float Sensors, which operate in tandem with Ultra-sonic Sensors, and senses the heights of the bed of stratified heavy feed layers at particular cut density. The heavy stratified fractions sensed by the Float Sensors are discharged through electro-hydraulically controlled Discharge Gate System.
The IMT Coal Jig provides three options for heavy settled material discharge – Rotary Valve System, Hydralic operated Discharge Gate System & Dewatering Bucket Elevator.
IMT under pulsated jigs sizes ranges from 0.5 meters to 5.0 meters wide with 2 products and 3 product designs. Amost all jigs supplied are with Alumina Tile Lined Jigs to ensure long life.
Combo jig designs available to process two different kinds of feed material in a same jig at the same time.
Successful installations are in Iron Ore, Manganees, Barytes and Coal.
