to take advantage of the motor's peak torque, or breakdown torque (BDT). A motor's BDT is typically as high as 180 220% of the motors full load torque (FLT). Using the VFD's constant Volts/Hz relationship, the VFD can be operated to provide motor starting torque equal to approximately 80% of the motor's BDT.

where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
