In most cases AG mills are high aspect mills The introduction and subsequent ascendancy of AG and SAG milling for comminution circuits has led to many economic advantages from high processing capacity energy efficiency lower investment and maintenance cost (Nunez F and Silva D 2011)

The model predicts the total comminution energy of most types of plant that contain conventional crushers High Pressure Grinding Rolls (HPGR) and wet tumbling mills such as Autogenous (AG) Semi-autogenous (SAG) rod and ball mills As well as the total specific energy it will also predict

Irrigated agriculture is a crucial part of global agriculture increasing productivity significantly However it is under pressure to adopt best practices to improve efficiency in terms of water use and energy costs Further areas for energy saving potentials within agriculture and energy are the diesel efficiency in agriculture and transport

(Fuerstenau and Han 2003) It is also reported by Haque (Haque 1999) that the energy consumption of AG/SAG mills (including operating power and the energy used during the mill components production procedures) accounts for 50% of the minerals industry and the efficiency

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach When future tonnage is to be increased the SAG Mill can feed downstream ball milling to boost capacity Fuller-Traylor SAG/AG Mills range in size from 4 3m through 12 2m in diameter with powers as high as 28 000 kW
