A Kinetic Model for Size Reduction in a Pilot Scale Tower Mill: Model Verification

Mark Duffy produced a complete set of grinding data on pilot-scale tower mill. Here these are analyzed in terms kinetics. The results show that the can be fitted with simple first-order breakage model, which is not normally observed any system, including other types machines such as tumbling ball mills and rod mills. model has only two parameters, making it possible to determine parameters using search methods. larger particles break faster than smaller particles, usually all Statistical analysis showed one could fixed for seven nine tests.
