Investigating the controllable factors influencing the weight loss of grinding ball using SEM/EDX analysis and RSM model
چکیده انگلیسی

This study was aimed to investigate the effects of individual variables and their interactions on weight loss of grinding ball using the SEM/EDX analysis and RSM model. The results SEM/EDX analysis indicated that corrosion mechanism type for steel balls is pitting. In addition, abrasive corrosion was observed on high carbon chromium steel ball surface. It was also found that steel balls were formed from corrosion phases of Fe, O, S and Si. The results of RSM model showed that the linear effects of all factors and the quadratic effects of solid concentration and charge weight of balls were significant parameters on wear rate. Also, it was observed no interactions between factors. Furthermore, results indicated that degree of influence of factors on the wear rate was in the order of ball type > solid percentage > pH > solid percentage2 > charge weight2 > grinding time > rotation speed of mill > charge weight > throughout.
