One of the important properties of aggregates affects the overall strength primary crushers in mill feed size optimisation? In terms of the three WipFrag fractions, crushing reduces the topsize (i.e. coarse) by generating medium and fine fraction material. Some of the medium material is also broken down. The pitfall to avoid is generating excessive critical size in the product or allowing medium-sized material Since the primary goal of this analysis is to determine the amount of energy absorbed by the tube as it is crushed, the most important output is the energy history output. Request the following history output to the output database *OUTPUT, HISTORY, TIME INTERVAL0.00008 *ENERGY OUTPUT ALLWK, ALLKE, ETOTAL, ALLPD, ALLIE, ALLVD, ALLAE, ALLSE
