Gunpowder, also known as the retronym black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive.It consists of a mixture of sulfur (S), carbon (C), and potassium nitrate (saltpeter, KNO 3).The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and

Feb 08, 2021 When using a ball-mill machine for grinding wet coals, its drying capacity limits the grinding capacity.
