The study on the crushing characteristics of vertical pulverizers in power plants was begun in 1930s. After the coal grindability index (Hardgrove grindability index) was proposed by Hardgrove, the basic theories of crushing and grinding characteristics were widely studied [2]. The crushing characteristics of the pulverized
