A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature (feed and discharge streams), mill power draw and the mass flow rate in the feed stream.
Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the chance of the material properties
