mining jig working principle,the process of mine jig

As coal mining increased mechanization, mixed with the increase in the amount of raw coal gangue, pulverized coal increased. After using the spray off the dust technology, raw coal moisture increases, the need to adopt new technology in the process and coal preparation equipment, which makes mining equipment is the rapid development of jig.
 
Mining jig that can both increase the Korea iron sand process capacity, but also increased the number of the whole plant efficiency and simplify the slime water system. Coal in the history of more than 100 years of the jig, the 1830 is a manual jig, 1840, sieve jig, 1848, invented the continuous operation of the mechanical transmission jig, it is a piston jump prototype of the jig. With the accumulation of technological progress and production experience, structure and performance of the piston jig With the new development.

 

At present, the internationally adopted jig is fixed sieve type for sorting metal ore, such as containing tungsten, gold-bearing sands, selection of tin, etc., can be used for selected fine material can also be used to Coarse materials, the maximum feed size is 6-8mm, sorting placer individual cases, the maximum particle size of 12mm.Paraguay Used hard crusher

 

In general, the jig is a deep trench type selected equipment, all of the jig jig room. Mining jig works: by punching steel plate, the jig indoor sieve woven made ??of iron mesh or grate bars, the water flow through the sieve into the jig room bed rises modest height and slightly loose state, the density of particles due to the partial pressure and the settling velocity into the bottom of the density of small particles is transferred to the upper.

 

When the water drops, the density of fine particles Europe Gold mining tools can also be adopted to gradually close the gap bed into the lower supplementary bodies of water movement instigated by density stratification in the early years of using piston, the piston chamber located in the jigging chamber flanking the lower part of the connectivity by the eccentric linkage to drive the piston up and down movement, thus completing the sorting task.
