A wide range of grinding media size can be used with typical bead sizes between 1-6 mm. Grinding applications can be classified as fine grinding and ultra-fine grinding: Fine grinding: F80 < 200 µm and P80 < 40 µm Ultra-fine grinding: F80 < 70 µm and P80 < 20 µm Media sizes are chosen according to application.
Principle of Operation: The rotary grinding shaft drives all grinding mediums inside the grinding chamber. The grinding mediums passes the powers to the materials to reduce the particle size. Gap separator inside the horizontal bead mills separates the products and the grinding mediums. They are suitable for different viscosities formulations.
Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002 ). The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm.
