The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond’s standard test procedure .For each iron ore sample, the RT taken to produce 250% circulating Ecoefficient and costeffective process design for ,The two options including AG mill circuits have between 27 and 32 percent higher power consumption costs relative to Option 4, which utilizes the more energyefficient autogenous grinding technologies. Grinding media and wear lining costs range between 0.41 $/t and 1.82 $/t.
autogenous grinding (SAG) of ores is the most progressive technology of ore preparation in world practice. As of 2010, in the world mining industry, about 200 large mills of full or partial SAG were in operation, including about 100 of them working in the iron ore industry, 30 in copper, while others in dressing ore ofAutogenous mill, Wet autogenous mill, Liners of ,A wet autogenous mill that materials as grinding media Feeding Particle Size 200350mm Product improvement Highefficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mil.
