Effect of lifters and mill speed on particle behaviour ...

May 01, 2017· When the mill works at a relatively high speed (ψ ⩾ 90 %), the mill power increases first and then decreases gradually with an increase in the lifter number. This outcome occurs because when the mill rotates at a high speed and with a large number of lifters, the particle area ratio increases and thus causes the mill power to gradually decrease.Chat Online
