Coal crushing Process. The general hardness of coal is 1-4. Following coarse crushing by jaw crusher, fine crushing by impact crusher, and sieved by vibrating screen, coal could be processed and crushed into different sizes of the requirements. TY jaw crusher, impact crusher for coal crushing have been widely utilized within the coal The liberation of minerals from coal by comminution is an important process taking place prior to the removal of minerals from coal substances. However mineral liberation with conventional mechanical comminution methods is difficult for middling coal in jig treatment which has increased the fine mineral particle content.

Analysis on the impact crushing dust generation test method

The impact crushing dust generation test device, developed by China Coal Technology Engineering Group Chongqing Research Institute, is mainly composed of a drop hammer, a guide rod, a crushing rod and a sample tank, as shown in Fig. 1.A certain mass of coal was placed in the sample tank and then crushed by the drop hammer freely Coal and gas outbursts are a dynamic phenomenon controlled by the geo-stress, gas pressure, and mechanical properties of the coal itself. They manifest as the rapid release of large volumes of coal, rock mass, and gas and are one of the common dynamic underground disasters (Guan et al. 2009; Tu et al. 2016; Zhao et al. 2016).Many Powder Mass of Coal After Impact Crushing: A New Fractal
