In 1976 Polysius adopted the design of shell-supported grinding mills using slide shoe bearings. Since this time, the design has been perfected based on the experience of more than 180 units operating all over the world in various industries. Today Polysius grinding mills are exclusively built as shell-supported units. Ball mill in iron ore bene-

incorporated in the shell lifter design. Increasing the shell liner face angles does reduce the impact point of thrown balls, and can reduce shell liner damage [5, 6, 15, 16]. In the recent years, DEM (Discrete Element Method) has been used successfully for modelling and analyzing the internal dynamics of grinding mill motion.
The Explosion of a Ball Milling Jar The sound of the other shoe (1997) By Lloyd E. Sponenburgh ver since I wrote the original articles on how to build a ball mill (AFN November 1995), I wondered how destructive an event it would be if a mill of my design were to explode while milling black powder. It was like waiting for the sound of

Ball mills are cylindrical or conical shell rotating about a horizontal axis, partially filled with a grinding medium such as natural flint pebbles, ceramic pellets or metallic balls. The common classification of ball mill is any type of mill in which mild steel or iron balls are ... design, that is, to try all possible combinations of settings.
The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application.

This is a mill jar which has been constructed from 5 inch PVC pipe and fittings. The milling media is antimony hardened, 3/4 inch lead balls. The construction of the jars is relatively simple, but is a subject for another project page. Finally, this shot shows the placement of the 5 inch mill jar in the cradle.

Outotec offers both trunnion and shell supported mill design, complemented by a drive solution tailored for optimum performance in any environment. Mill bearings The type of support bearing is selected on the basis of mill size, intended duty and environmental conditions at the installation site.
the first GMD for a double-rotating ball mill in Carlin, Nevada, meeting a 160 °C heat challenge at the mill shell. GMDs have now been supplied for the world's largest autogenous (AG), semi-autogenous (SAG) and ball mills, fulfilling the highest power requirements while operating under extreme environmental conditions. Focus on the future
semi-autogenous (SAG) mill and two ball mills, each with 13 megawatts (MW) of installed power, was expected to be SAG mill limited when treating competent basement rock. Ausenco Services Pty Ltd (Ausenco), was engaged to help optimise and enhance the productivity of the Phu Kham comminution circuit over an eight-month period.
The second type of ball mill considered in this paper is the vertical ball mill. Vertical ball mills, as the name suggests, have the mill shell oriented in the vertical position. Unlike their horizontal counterparts, the mill shell does not turn. However, feed size reduction is accomplished through a similar mechanism as the horizontal mill.
