China Juxin Jigger machine is one kind of mining separator to separate light and heavy materials against their different terminal velocity in vertical alternate waterflow. TTJ series of jigging machine is mainly used to handle placer gold, tungsten, tin, hematite and beach placer.

New type jigger machine has advantages as follows.
1.stepless speed regulation.
2.the machine vibrates evenly and the minerals can be processed uniformly.
3.low water consumption.
4.low maintenance.

5.it has remarkable adaptability and is especially good at handling medium and fine minerals.

China Juxin TTJ series of coal-dressing jigger is revised and manufactured, based on the stratified theory and the adequate analysis of other conventional jigs. The jigging pulsation curve----produced by sawtooth wave jig----is in the shape of sawtooth wave which makes upward water flow quicker than downward water flow. The feature that upward time is shorter than downward time solves the problem that time and action of upward/downward water flows. This breakthrough dramatically amplifies the loose degree and mitigates suction action, which facilitates precipitation of coarse ores and improves ore recovery rate.
