Frequency domain characterization of torque in tumbling

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 load.

Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

BALL & ACME LEAD SCREW TECHNICAL INFORMATION I

the performance of ball screws is far superior. The rolling action of the balls versus the sliding action of the ACME nut provides significant advantages. Advantages of ball screw drives are increased efficiency (typically up to 90 95%) which allows required motor torque to be lower, predictable service life, low wear rate and maintenance

shell lifter profile changes through wear. The energy required to lift and throw charge (aimed to generate high-energy ball-rock impacts at the charge toe) can be estimated from the lifting rate and height of lift of mate-rial between the shell lifters. The energy required is a minor proportion of SAG mill power and this proportion falls as the

The torque speed characteristic of a typical ball mill is shown in Figure 1. On this curve there are three distinctive points of interest, which uniquely characterize the ball mill operation. Figure 1 a) The breakaway from rest is identified as the region on the graph requiring 40% to 70% of nominal torque from rest to approximately 20% speed.

Effect of lifters and mill speed on particle behaviour

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.
