Grinding is modelled as a packing of particles connected by interparticle bonds that are characterized by a given force-displacement relation for the nomal and tangential components. Particles on the surface of the packing may be break or sheared off if the forces between particle contacts exceed the strength of the bonds. The forces between contacts due to surface fraction are calculated based on the principle of equilibrium and the compatibility between particles. The parking of particles is generally random and the surface friction including normal and shear stresses be a function of time (i.e. variable speed of grinder). The roughness of the surface is smoothed due to the “BREAK OFF” of surface particles. The mechanism is modelled microscopically to provide more insight to this phenomenon. The calculated results are compared and disscusseed with existing theories such as Prinston Equation to show its validity.
