This diamond mine in China firstly adopted multijigging( 16+8mm, 8+4mm, 4+2mm, 2+1mm, 1+) with the max. feeding size of 16mm. This processing line needs multilayer screens, which makes the plants alloion hard and waterconsumption large. And aiming at solving the difficulty and the sophistiion, the single jigging can be used instead of multijigging.
