Working Principle

The KXT mineral jig consists of a cell containing water with a perforated horizontal screen on the top. Steel shot or stainless steel shot or a thick bed of coarse particles is placed on the screen. A rubber diaphragm located at the bottom of the cell is driven up and down by a walking beam and eccentric mechanism. Water is pulsated up and down by eccentric-driven diaphragm.

On the upward stroke of diaphragm mechanism, a pulsating current of water dilates the jig bed so that heavy particles move to the bottom and light particles to the top of the bed. On the downward stroke of diaphragm mechanism, heavier particles are pulled down through the bed and discharge through the hutch concentrate valve at the bottom. While the light particles are carried away by crossflow supplemented by a large amount of water continuously supplied to the concentrate hutch to enter the next jig cell or to be discharged as tailing.

Feed rate, depth of bed, pulsation frequency, stroke length, and make-up are main variables to adjust the jig for optimum recovery.

Features

1. High recovery rate of gold. The jig can improve recovery rate of gold from 5% to 40%. It also can recovery the gold as fine as 270 meshes;

2. Improve production efficiency.The jig can continuously discharge the concentrate when operating and there is no need to stop the machine for collection of concentrate;

3. Strong adaptability: The jig is not only used for placer and rock gold mines, but it can also be used for recovery of heavy minerals such as iron, tin and tungsten ore;

4. Simple operation and easy maintenance. As the machine has few moving parts,it is very reliable in operation.
