A Mine-to-Crusher Model to Minimize Costs at a Truckless Open-Pit Iron
Innovation has an important role in improving the productivity, safety and sustainability of mining operations. Historically, ore transport was done by diesel trucks, but with the commitment to reduce CO2 emissions and increase mine safety, mining companies have invested in innovative, more sustainable ore transport technologies. The innovative Tower Mills: 0.5”-1.5” grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1” grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).Grinding Balls and Other Grinding Media: Key consumables

Advances in screening technology in the mining sector
3 Screening machines for iron ore and coal. The crushing and screening systems for iron ore processing vary widely, depending on whether a magnetite or hematite deposit is being mined. While good quality magnetite is now dry-processed, hematite from deposits below the water line requires wet processing due to sticky quartz and clay contaminations.Spherical balls are better for crushing large particles by impact due to their point of contact between the grinding media and the ore. Spherical balls are manufactured using cast iron, low-alloy and high-alloy carbon steels. Alloy steels are made by the addition of alloying elements like chromium, aluminium, manganese, and silica.
