Assessment of comminution energy intensity has traditionally been confined to the crusher and mill motor power consumption. However, a measure of ancillary equipment power and the embodied energy consumed through media wear is required to compare disparate equipment types and circuit configurations fairly, as they can contribute a significant (average 45% increase) proportion of energy

Get PriceEnergy studies for the SAG-ball mill circuit and regrind/flotation circuits were carried out in 2018/2019 to identify opportunities for energy conservation and improving production performance. A summary of the key findings is presented in this paper. The SAG and ball mill circuits are responsible for 59% of mine-wide electrical energy consumption, equating to 195 GWh of annual consumption
Get PriceComminution and Mill Energy Requirements Comminution includes both crushing and grinding. Initially, ore is reduced in size by crushing rock to a size that makes it manageable. Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Crushing is usually a dry process, and is performed in several stages, reduction
Get Price1/1/2016 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. The

Get PriceTraditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling. However by far the most important factor for fine grinding is media size and therefore the breakage rate. Small media has a larger surface area which translates to better transfer of energy. Although Tower Mills are full attrition grinding
