Apparatus for determining breakage properties of particulate material

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;
• and
• wherein the control system includes a processing unit for receiving an input of the circumferential speed of the rotor and correlating this with the actual impact velocity of a particle emitted from the guide channel of the rotor.
