Comminution test method using small drill core samples
The developed test method aims to characterize the essential comminution properties of small samples in a single (combined) test. This is an ambitious goal since most of the geometallurgical programs use different tests for different particle sizes. It is common to do separate characterization tests for crushing, SAG grinding and ball millAs shown in Table 1, the calculated energy consumption for the comminution circuit was about 130% of the theoretical energy calculated using Ausenco's Ausgrind methodology (Lane et al., 2013(PDF) Power-based comminution calculations using Ausgrind

A new approach to the calculation of bond work index
Mining comminution processes are the most energy intensive, and also the area with the greatest potential for energy savings. Accurate determination of the BWI is essential for the proper design and estimation of the costs associated with the comminution process. Based on the obtained results, which are shown in Table 1, they gave theComminution has been identified as a relatively large consumer of electrical energy, being responsible for up to 60-70% of a mine-sites power requirement (Daniel et al, 2010; Buckingham et al(PDF) EFFICIENCY, ECONOMICS, ENERGY AND

Crusher to Mill Transportation Time Calculation—The Aitik
Comminution is a major contributor to the production costs in a mining operation. Therefore, process optimization in comminution can significantly improve cost efficiency. The mine-to-mill concept can be utilized to optimize the comminution chain from blasting to grinding. In order to evaluate the mill performance of the ore from a specific Each packing calculation is performed on the fly in the DEM code since no two particle breakage events are identical and so use of pre-computed or simplified packings creates a significant risk of biasing the product size distributions predicted by the model.
