Machine product

Original: China

Jig machines need water to work, and it loosens materials in vertical alternative water-flows, and it forms different layers of materials of different densities and discharges both layers from up and down discharging ports separately. The basic composition of jigger is jigging chambers, also called jigging boxes, and there are screens in each chamber.

Water and raw ore will be fed from one end of the jigger screen, the ore granules will move in the vertical alternative water-flows. Layers will be formed because of density difference of materials. The minerals with small density will be in the up layer and will flow together with the up pulp flow while material with bigger density will be in the down layer and will discharged from the down discharging port as jigging concentrate.

Main product

Name: Spiral concentrator
Brand: GANDONG
Original: China

Spiral Chute is working under the the force of water flow, gravity, inertial centrifuge and friction. Slurry is pumped to the top of the spiral , and it enters a feed distributor that evenly distributes the feed to each spiral concentrator. The design and shape of the spiral make it work, when combined with gravitational acceleration. As the slurry travels the spiraling path down the spiral, mineral grains settle and start sorting according to size, density and to a lesser extend shape. Low density particles arecarried with the bulk of the water towards the outside of the spiral , while particles with the greatest density migrate towards the inside of the spiral.
