A particle size reduction model has been developed as the first component of an upgraded ball mill model The model is based on a specific energy size reduction function which calculates the particle breakage index t 10 according to the size specific energy and then calculates the full product size distribution using the t 10 t n relationships and the mass size balance approachfrequently used interchangeably Usually however a ball mill is referred to as one that uses steel balls as grinding media while a pebble mill is one that uses flint pebbles or manufactured ceramic shap Fundamentally milling is a process for reducing the particle size of solids to some required degree of subdivision It is also a method
