Abstract: the time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. this paper looks at the serviceability and economics of five different mill motor options to meet these.
Ball mill motor power draw sizing and design formula. the following equation is used to determine the power that wet grinding overflow ball mills should draw. for mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the.
Jan 01, 2018 by means of a flange type torque sensor, the torque signal is recorded when the motor is driving a constant torque load, (fig. 1(a)), and a ball mill, (fig. 1(b)). the presence of an oscillating component of around 2 nm, superimposed to the average value, can be observed in the case of constant torque.
The torque of liners and baffles are affected by lifter height, lifter number, and mill speed. moreover, the changes in the torque and power consumption of a ball mill can be effectively explained using two important factors: lifter and particle area ratio. keywords: experimental study, particle behaviour, ball.
