Effect of lifters and mill speed on particle behaviour

The power consumption is usually determined by charge fill level, lifter height, lifter number, and mill speed However, almost all of the classical theories for calculating the power consumption of ball mills disregard the effect of lifters and only focus on rotation rate, charge fill level, as well as size and shape of grinding media, thereby Bian et al [9], investigated the effect of lifters and mill speed on particle behavior, torque, and power consumption A 3D model was used for trapezoidal lifter, and concluded that the torque is Effect of lifters and mill speed on particle behaviour Sep 22, 2020 Jan 01, 2007 The discharge rate of the product material depends on how efficiently the discharge pump (grate and pulp lifters) is operating Similar to the impeller design affecting the pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of the SAG/AG grinding millseffect of grate discharge area of sag mill performance
