AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K Ï b LD 2.5 where k is a proportionality constant.

How to Ensure Greater Efficiency with Reliable Plant

VFDs may work best with applications that require full torque at zero speed. They can produce rated motor torque from zero to rated speed and even provide full torque at no speed. Soft starters, on the other hand, typically operate between the frequency of 50 to 60 hertz, and full torque can only be achieved at full voltage.

The Power of Pareto Analysis in Maintenance Reliable Plant

In a large pulp mill, a study of three years of equipment-level downtime records showed that, of the more than 12,000 items in the plant, 87 (less than 1 percent) caused 80 percent of all unscheduled maintenance downtime. The establishment of a PM program for these 87 items reduced the unscheduled downtime by more than 50 percent within 18 months.
