A study of the energy-size reduction relationship in impact crushing of coal

摘要: Abstract Size reduction is an important step in the processing of coal due to advent pulverized fuel boilers, requiring run-of-the-mine coals be reduced size order tens microns. The main operating cost pulverizing plant power required drive plant. study energy-size relationship thus vital importance economy electric stations. This report describes work performed on five South African determine relationships impact-crushing environment. A hypothesis for proposed and its validity tested experimentally.
