Energy Consumption in Crushing and Grinding

2018-1-25  The ore passes through primary and secondary crushing and grinding. The final product is 80% passing 270 mesh. Bond has published a Wi for taconite of 14.87 (1961). This value is used in these base case calculations. Table 1 shows the feed and product size, the calculated total energy input, and the energy cost for each unit operation.

THE EFFICIENCY OF BLASTING VERSES CRUSHING AND

2013-4-21  Then explosive energy is .473 kw-hr/lb and blast energy is .426 kw-hr/long ton. Since the measured energy for size reduction from in-situ to final product is known; the value for the Bond work index can be calculated. This value is then used to estimate the energy required for each step: blasting crushing and grinding.
