Comminution is the oldest mechanical operation for the size reduction of solid materials and is an important step in many processes where raw materials are converted into intermediate or final products. It is the most widely used method of powder production for hard metals and oxide powders. ... The stockpile permits steady, controlled flow of ...
This is obtained for a comminution device using Eq. (5.4), by measuring W (the specific energy being used, kWh t −1), F 80 and P 80 and solving for Wi as the operating work index, Wi O. (Note that the value of W is the power applied to the pinion shaft of the mill. Motor input power thus has to be converted to power at the mill pinion shaft output by applying corrections for electrical and ...
