5 Product particle size The HPGR is capable of handling particle sizes up to approximately 80mm. The essence of the process is to avoid single particle crushing and to aim for a compressive grinding of the material in the particle bed. Single particle crushing would increase the wear of the roll surface through high point-loads and shear, and would cause damage to the autogenous wear surface.
