Dynamic Modelling of Temperature in a Wet Ball Mill

2019-9-1 · A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances. The energy balance relies on temperature and mass flow data. The key model parameters to be measured are mill temperature in the feed and discharge streams, mill power draw and the mass flow rate in the feed stream.

Ball Mills - an overview | ScienceDirect Topics

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.
