by a single parameter known as the e ective ore grinding rate K . If we denote the ore mass greater than sized i in the chamber asW i+1, and if K i is the e ective grinding rate for ore of sized i, we have the grinding relationship given by (1). Power consumption and load fraction variables are closely related. For the mill we are modeling ...
A SAG mill with a 44'' () diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.
Usually, the grinding circuit contains at least two interconnected mills with material classifiers ( cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill ...
For a single mine, average comminution energy consumption can be approximately 6,700 kWh /kiloton. Grinding is accomplished by abrasion and impact of the ore with moving media such as rods (rod mills), balls (ball mills), or pebbles (sized ore in AG SAG mills). These vary in size according the size of particle being processed.
