Temperature progression in a mixer ball mill

Mechanochemistry using ball mills is a promising tech-nique with applications in organic and inorganic chemistry as well as material sciences [1–4]. During ball milling, up to 80 % of the energy that is generated in the mill is dis-sipated as heat [5]. This is why measurement and control of the temperature in the ball mills is important, for ...

Ball Mills - an overview ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The gas temperature is controlled by cold-air bleeds to ensure a dry product without overheating the mill. The product passes into an air separator, which returns oversized particles to the mill inlet. Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill.
