In year 1556, dolioform ROM Jigging Bath was used for mineral processing, since early 1800s it was applied into coal washing, and in 1950s, it spreaded all over coal mines in middle Europe.
The structure of Baum jig was simple in early stage, it consisted of U-type machine body, sliding piston valve and discharge manually. In 1930s, manually discharge was replaced by motor-driven or hydraulic pump-driven mechanical control. The sliding piston valve was changed to rotary piston valve in 1950s, and in 1960s it got a further development to electrically controlled pneumatic air valve, since 1980s, this kind of piston valve was controlled by computer numeric CNC gradually.
In year 1954, Japanese professors Dr. Gaosang and Dr Songcun proposed the air chamber jig under screenTACUB jig and it was applied at Chiping Coal Washing Plant in Hokkaido, in 1958. One feature of this jig is that, the air chamber was removed beneath fixed screen deck from side, it is lighter than Baum jig, and needs less space, also it is equally distributed along with the jig chamber water turbulence.
ROM Jig is original machine type of jigging technology, however it didnt get popularization and application. Now new type product was developed and it can replace reject discarding by manual picking, maximum particle size could reach up to 300mm, with advantages of big capacity, good separation effect and less water consumption, which broadens application scope of jigging coal washing technology.
Jigging coal washing technology means a kind of coal washing method by gravity, in the vertical fluctuating medium mainly water, the feeding material realizes layering according to physico-mechanical propertiesmainly density. Jigging coal washing technology is mainly divided into two processes, material layering and product separation.nbsp
