Figure 3.
Panel A contains a laboratory crushing machine mounted on a metal frame, with an inlet, operating components, and an inclined outlet chute. Panel B illustrates two jaw configurations. Each configuration has a fixed jaw, a rotating jaw, a material inlet marked Feed, and a material outlet marked Product. Both jaws measure 42 centimetres in height. Angle one has an approximately 9.2 centimetre inlet, an approximately 5 centimetre outlet, and an alpha one angle of 90 degrees. Angle two has an approximately 10.5 centimetre inlet, an approximately 2.5 centimetre outlet, and an alpha two angle of 85 degrees.a) Lab-scale Smart Crusher and (b) schematic representation of the crushing set-up showing the material inlet (feed), outlet (product) and the nip angle (α1 = 90° and α2 = 85°) of the moving jaw
