摘要： An apparatus for determining the breakage properties of a particulate material, the apparatus including: a support; a rotor mounted relative to the support and including at least one guide channel through which a particle of the particulate material is guided in use, the guide channel having an inlet and an outlet; a drive associated with the rotor; a feed channel for feeding particles of the particulate material to the inlet of the guide channel; a stator associated with the rotor and including an impact surface that is radially spaced from a circumferential edge of the rotor; and a collector for collecting pieces of the particulate material following impact; wherein the apparatus is provided with a control system for accurate control and adjustment of impact velocity of the particulate material with the impact surface.

摘要： A method of predicting breakage properties of a particulate material when subjected to impact, the method including: calculating a breakage index for the particulate material using the following equation: Breakage Index=M{I−exp[−fmatxk−E]} where: M represents the maximum breakage of particles for the particulate material; fmat is a material parameter that is a function of the particulate material being broken and particle size; x is the initial particle size of the particulate material prior to impact; E is a measure of the specific energy applied to the particulate material; and k is the number of impacts with specific energy E.
