Graphical abstract. We proposed an improved mass model for the estimation of coarse coal particles using image analysis, which was only consisted of two variables, projected area and density of coal particles. A series of experiments was designed to establish and test the improved mass model, and some conclusions were acquired.

At present, much work on coal separation using a highdensity gasvibro fluidized bed has been conducted. (18−20,27,30) Separation density data were collected for comparison. For lowdensity separation of fine coal, magnetite powder (110 μm) and quartz sand (200 μm, 40%) were mixed to decrease the separation density in the study.

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.
