2012-5-1 · The input mass flow of the raw coal to the mill is difficult to measure as well; typically, the conveyor belt speed is used for this purpose. Additionally the varying coal quality, e.g. Hardgrove Grindability Index (HGI) and moisture, of coal fed to the mills varies, and general mill wear cause parameter changes ( Fan, Rees, & Parker, 1997 ).

2014-8-5 · A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln. The method is based on the principle of granular movement in a kiln as described by Saeman (1951) and Scott et al., (2008). It assumes the kiln is operating in the rolling regime, the active layer has zero thickness, and the ...
