particle size distribution graphite ore

Research on prediction model of ore grinding particle size

The results show that particle size distribution of crushing products under different crushing energies and ore particle sizes is obtained by drop weight test and the crushing parameters A and b are calculated by fitting regression and then the correlation between t x and t 10 obtained in drop weight test is also applicable to the correlation...
