Application of jigging separation process at Zhuanlongwan Coal Preparation Plant

Despite the fact that jigging process is gradually replaced by heavy medium separation process, Zhuanlongwan Coal Preparation Plant still adopts jigging process. According to analysis of the performance of each operation system in the past 3 years, the jigging process works remarkably well when used for treating high-grade raw coal and even the degradation-prone high-ash raw coal produced during the period when working face passed across fault. For treating high-ash raw coal, an effect better than heavy medium separation process can be expected. Application of jigging process at large-sized power coal cleaning Plant can also poerate reliable with favorable economic result.
