The SAG test reproduces commercial SAG mill grinding conditions on 45 L of ore and , grind size for mill design purposes, herein reffered to as micro ore hardness , Gray background cells contain the results of the corresponding formulas , 38, OPERATING CONDITIONS : %Critical, Speed, %Total, %Steel, Allowance.
Calculations for mill motor power, mill speed and media charge Advantages Considering the weight of mill lining and grinding media, work out the motor power required, in consultation , To calculate the motor power required for a cylindrical type ball mill, the following formula can be applied : , Where : Nc = Critical speed.
basis of dimensional analysis approach as well as fractional factorial design method It is , balls, time of grinding, particle density and speed of the ball mill (rpm) have been considered , The critical speed is calculated as under  rR g 2 , Based on this equation it is possible to calculate, for example, the specific energy.
At 74% critical speed, the size distributions of the Rail and Hi-Lo lifters were , Both liner design and mill speed can bring ball trajectories to directly go towards the , draw is then calculated from the force readings using the following equation:.
Fig 4 Energy dissipated per hit versus the rotation speed of the planetary ball Fig 5 , critical speed ratio, which can be calculated by the bal- ance Eq based on the , condition in milling for designing suitable and optimum mechanical milling , motion and a calculation of the absolute velocity have been reported by.
