The Modelling of Autogenous Grinding
— Lumps in an autogenous mill should be defined as particles having suffi- cient kinetic energy to provide ener- gies above critical in other par- ticles they collide with. Lumps are also ground during milling and have a probability of hit S,,,,=I. This is the main diffrence in mill models and make ball mill models ob- solete.
