Coal Mining Methods

Advantages of Longwall Mining Longwall mining is a very efficient coal producing technique. Longwall productivity is potentially higher than that of room-and-pillar mining, because longwall mining is basically a continuous operation requiring fewer workers and allowing a high rate of production to be sustained. The amount of coal recovered is also

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.
