Jig machine using reciprocating movement of the screen frame to force the material stratification, change the ordinary jig machine using diaphragm drumming water flow to produce pulsation to force the material stratification principle, with the effect of mandatory stratification, while increasing the handling capacity of the jig machine and the size of the entry, the entry of the grain size, water consumption has dropped significantly, become the current water-saving jig machine equipment.

Advantages of using jigger:

(1) The use of jigger process is simple, saving investment, compared with the previous heavy media gangue and traditional jigging gangue, can save times the investment.

(2) The feed size is large, the upper limit can reach 350~400mm, which can solve the problem of mixing raw coal and gangue crushing. The jigger can separate the gangue after the gross coal is lifted to the wellhead, creating conditions for the later crushing process, effectively avoiding the crusher to crush the gangue. Especially for the gangue is easy to sludge the mine is more favourable.

(3) and mining mechanisation to improve matching. At present, the degree of coal mining mechanisation is higher and higher, encountering faults are generally forced through, instantaneous gangue mixing rate increases rapidly, with jigger can be mostly excluded without affecting the quality of coal.

(4) Can cancel the manual gangue selection. For the mine scale is expanding, artificial hand-picked due to its low efficiency, labour intensity, has been unable to adapt to the requirements of modern mine production. The use of jigger gangue is the ideal choice to solve this problem, can reduce staff and increase efficiency, improve the degree of modernisation of the mine, for the construction of high-yield and high-efficiency mines to create the conditions.
