Size Reduction and Energy Requirement - ScienceDirect
2016-1-1 So a measure of size or surface area before and after size reduction would indicate the extent of energy expended in the comminution process. Hence if E was the energy used for a desired size reduction, which resulted in a change in surface area S , it has been found that [13] , [14] , [15] , [16] , [17] : (3.1) d E = k [ S n d S ] where k is a constant and a function of the crushing strength of the rock.

Energy Use of Fine Grinding in Mineral Processing
2013-4-25 unit operation in mineral processing. While fine grinding can liberate ores that would otherwise be considered untreatable, it can entail high costs in terms of energy consumption and media use. These costs can be mini-mized by performing adequate test work and selecting appropriate operating conditions. This paper reviews

2017-3-19 energy-size reduction to the control of circulating load was studied by the experimental simulation method. Coal mixtures with fine/coarse ratio of 11:1, 8:1 and 6:1 were ground by a lab-scale roller mill. Energy-size reductions of the coarse coal were compared to evaluate the influence of circulating load control.
