An underground gross coal gangue removal and mine water treatment combined process is characterized in that the process comprises two parts: gangue removal operation from lump coal and mine water solidliquid separation operation, wherein, the gangue removal operation from lump coal comprises screening, crushing and separation steps, and the mine water solidliquid separation
products are taken to the discharge shafts over movable jig beds (swing bed) of maximum m width. Wider jigs use several movable jig beds in a row. all jig beds can open up to 350 mm to allow all sinks to discharge. The shaft walls are protected against wear by ceramic tiles or special wear plates. Fine and mediumgrain discharge deVices.
When the refuse gate is closed, rock and heavy impurities are prevented from exiting the jig bed. Coal product, however, continuously overflows the above the refuse gate and passes out of the jig As a new feed enters the jig, the rock and impurities build up, causing the aluminum float to gradually rise.
Movable Sieve Jig Fine Coal Discharge Gate. Movable Sieve Jig Gravity Separation Equipment. 2 Less water consumption,Movable Sieve jig forced through a sieve of vibration layered material, Water consumption is only onetenth of the ordinary diaphragm jig. 3St roke and the number of stroke are easy to adjust.

The Allair jig is a modern version of the Stump jig (1932) and the Roberts amp; Schaefer Super Airflow table (1942) which were popular dry processing units in the United States. Dry processing of coal in the United States peaked in 1965 when some 25 million tonnes of clean coal

May 01, 2017#0183;#32;The paper presents a simple dynamic model of coal product discharge in a jig. The model is based on the principle of mass conservation of coal density layers transported in the jigs bed. It can be used to investigate dynamic properties of a discharge zone in a jig and to design control systems of products discharge in a jig.

However, the current moving sieve jig has a larger machine body an d a discharge device, the structures of which need to be optimized for underground applications.
Jigs represent one of the earliest types of machinery employed in mineral separation. Their adaptation to process coal established jigs as the most popular and efficient method of coal cleaning
A novel preparation process for predestoning refuse of up to 400 mm from ROM coal was designed and developed in cooperation with KHD Humboldt Wedag AG, Cologne, and a prototype of a movingbed jig
This machine is mainly used in coal selecting, dressing industrial sector and ore tailing dehydration, forced dehydration for vulgar, middle, fine particle material. This series dewater screening has big dealing capacity, high efficiency dehydration, compact structure, long service life, is suitable for dewatering operation in fine ore and tailing ore dehydration.
The former mainly includes jig and movable sieve jig for separation, while the latter mainly refers to shallow trough, inclined wheel, heavy medium cyclone and spiral rolling equipment for separation. The lower limit of separation granularity of these coal separation equipment is more than 13 (25) mm.
The most commonly used UDCG methods are selective crushing, movable sieve jig, and dense mediumshallow trough (DMST) [20] [21][22][23][24]. Table 2 summarizes the advantages and disadvantages of
Typical fine and mediumsized material jig for coal and ore applications. Wider jigs use several movable jig beds in a row. all jig beds can open up to 350 mm to allow all sinks to discharge. middling products are discharged into bucket elevators or equivalent discharge devices via the jig discharge gates and the chamber bottom outlets.
The movable screen jig is a singlecut machine developed for primary separation of rejects from the coarse raw coal of 400 30 mm size. The applications of the romJig have been extended to include preparation of steam coal and the cleaning of coarsegrained rubble.
