Quartz grinding specific rate of breakage (Sj) classification by discriminant analysis

Abstract

Specific rate of breakage (Sj) is an important parameter for grinding kinetics behavior due to it isreverserelated with the process energy consumption. Size grinding media, viscosity medium, and fine particle formation are some ofmodifiablevariableforto reduce the energy in the grinding process.Nowadays, there is no model that explains the relationship among Sj and parameters described above.Aclassification model based on linear discriminant analysisfor quartz wet grinding wasproposedto identify conditions with the high Sj.Three grinding kinetic behavior groups have been found through cluster analysis and two discriminant functions that explicate difference among groups. The first function was themost powerful differentiating dimension with 89.01% of prediction percentage,and the second onerepresented an additional significant dimension with 10.99%of prediction.
