The purpose of wrapping ball mills with thermal/acoustic blankets is twofold: (1) to maintain the desired temperature inside the mill and (2) to reduce the sound emanating from the mill. This field case study focuses solely on the latter, evaluating and documenting the sound level reduction attributed to the installation of the blankets and its potential to reduce the noise dose experienced by .
Ball mill operating at correct speed Exercise A d v a n t a g e s The mill may be used wet or dry although wet grinding facilitates the removal of the product. The costs of installation and power are low as compared to other mils. The ball mill may be used with an inert atmosphere and therefore can be used for the grinding of explosive materials.

The tumbler ball mill is operated closed to the critical speed beyond which the balls are pinned to the inner walls of the mill because of the centrifugal force dominating over centripetal force. For large scale production tumbler mills are more economical when compared to the other high energy ball mills.
A steel ball is a ball, or sphere, made of steel. An example would be a ball bearing, and the whole world runs on bearings, many of which are of the ball bearing variety.
