Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.SINGLE STAGE SAG/AG MILLING DESIGN - Orway,4 High ball charge SAG mill or ROM Ball mill (15 to 25% ball charge) Low competency ore Hidden Valley, Nzema, Sepon, UG2 ores (South Africa), Yanacocha 5 Low ball charge, high speed SAG mill (4% ball charge, 90% Nc) A cross between AG and SAG for average competency, abrasive ores. Typically operated in RSA on Witwatersrand Gold Ore Driefontein,SAGDesign Test | Starkey and Associates Inc.,The SAG mill pinion energy, W SDT (kWh/t) and SAG discharge Bond ball mill work index, S d-BWI (kWh/t), are then used to calculate the total energy to grind the ore from 80% passing 152 mm to 80% passing the client specified final product size P 80.This information, along with the ore specific gravity, is used to calculate necessary mill sizes and motor power in industrial applications.AG & SAG Mill for Mineral Processing, - Ball Mill for Sale,In this case, the SAG mill design can do that. In general, the SAG mill manufacturers will control the addition amount of medium such as steel ball at 2-8%, so that the capacity of semi SAG mill to process materials can be increased by 10-30%. The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during,
