To determine the selection function for a particle size class, a semilogarithmic curve of the remained mass on the screen vs. grinding time is plotted. Then, as grinding process of homogeneous ore follows a firstorder kinetics, the slope of the line fitted to data ...
WhatsApp: +86 18838072829This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.
