Learn MoreGunpowder, 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
Learn MoreHorsepower and torque ratings alone don't provide enough information to make an informed decision about a motor's potential performance. Unfortunately, some CNC machine builders use off-the-shelf motors that may appear to have adequate HP ratings, based upon power consumption rather than actual output, and may not meet other important criteria.
Learn MoreKeywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

Learn Morethe desired motor power and drive rating, the maximum design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and
Learn MoreApr 21, · So, for the longest time engine power ratings have been equated through the “horsepower” scale. But as engine technology has advanced, what was once as simple as finding the right diameter of coupling for your steam pipe is now a game of exact distances. Often measured in centimeters. Specifically “cubic centimeters” or “CC’s”.
Learn MoreFor example, ring-geared mill drive (RMD) systems are good solutions when the power required to drive the mill is under 18 MW, i.e., a maximum of 9 MW per pinion (Fig. 4). Yet as tube mills grow in size in order to meet the demand for larger throughputs, the power required to drive them increases.
