Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption). However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.

AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.
AC Replacement for DC Mill-Duty Motors For many years, DC mill auxiliary motors for steel mill applications were specified as Type MD. Many of these motors have been replaced with less-rugged DC or AC motors. This paper reviews the features of direct-replacement AC mill auxiliary motors.

Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball
High voltage motors for mills More for mining ABB’s motors for mill applications are built for high levels of performance, quality and reliability in harsh conditions. They meet high demands for availability and help mining companies to operate mills continuously 24/7. Perfect compatibility with mill
The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8.4 The speed of rotation of the mill influences the power draft through two effects: the value of N and the shift in the center of gravity with speed. The center of gravity first

Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.
use in the mining industry: iron ore-mill with a 21-foot diameter ring motor. The project was completed in 1980 and opened the door for subsequent projects. As output volumes continue to rise in ore mines, the demands on mill drives are also growing. In
