  • Air classifier - Wikipedia

    An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.[...]

  • Cyclonic separation - Wikipedia

    A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets ...[...]

    During the initial pass, the feed material is directed as a falling curtain into the GIC, which seperates it at any cutpoint between 63 μm and 300 μm (50 to 230 mesh). Particles that meet the first specification are removed and the rest enter the CC, which separates material with a cutpoint between 15 μm and 100 μm (150 to 950 mesh).[...]


    The ‘as received’ samples were air dried and thereafter split using a vibratory rotary divider into approximately 20kg sub-samples for the spiral testwork.
