The truck fleet size is determined by evaluating the model that is based on the mine's production capacity and operating parameters, specifically, the average haulage distance (AHD). These two factors are very important as they hold a great weight in the decision to use the IPCC system (Nehring et al. 2018NEHRING, M., KNIGHTS, P. F., KIZIL, M. S., HAY, E. A Comparison of strategic mine planning approaches for in-pit crushing and conveying, and Truck/Shovel Systems. International Journal of Mining Science and Technology, v. 28, n. 2, p. 205-214, 2018.). By selecting the truck size (model) from one of the four options, the number of trucks is calculated, as well as the number of bulldozers and motor graders required (Figure 1). It is worth mentioning that, because the transportation model considered in this study is a SMIPCC, it is still necessary to use trucks to move the material from the mining face to the in-pit crusher, where it will then be crushed and loaded onto the conveyors (McCarthy 2011MCCARTHY, R. In-pit crushing and conveying: fitting a square peg in a round open pit. Proceedings CIM Montreal 2011. Montreal, Canada: Canadian Institute of Mining, Metallurgy and Petroleum, 2011.; Mohammadi et al. 2011MOHAMMADI, M., HASHEMI, S., MOOSAKAZEMI, F. Review of in-pit crushing and conveying (IPCC) system and its case study in Copper Industry. In: WORLD COPPER CONFERENCE, 1. Proceedings... 2011.). Therefore, only the AHD from the mining face to the in-pit crusher is considered in the SMIPCC sizing, whereas the entire route is considered for the conventional model. In Figure 1, the AHD node indicated by [1] is subject to change based on the material transport alternative selected. The output nodes, indicated by [2], can be determined by using a rule of thumb based on the required truck units of one bulldozer for every 20 trucks and one motor grader for every 15 trucks, with a minimum of one unit in both cases

The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow, the media will not cascade much from one end to the other

In experiments carried out by Jung, (1980), the solid residue of Loy Yang coal remaining after the drying and devolatilisation phases comprised about 20 percent of both mass and volume of the original coal and required about 80 percent of the overall burn-out time for combustion. The burn-out time of the residual char was found to be insensitive to the mass of char in the batch charged, indicating rough proportionality between the burn-out time and the initial particle diameter. A similar result obtained by Jung and Stanmore, (1980) is shown in Figure 8.21. Increasing the initial particle size from -5.6 + 5.0mm to -8.4 + 6.4mm has increased the burn-out time by 50 percent. This suggests that combustion of the residual char is probably kinetically controlled. Further to this, however, Jung and Stanmore, (1980) measured the size and density of a single particle of Yallourn char after various combustion times in an electrically heated fluidised bed of sand. The particle showed a regular decrease in diameter with constant density as it burned away at a bed temperature of 1043K. From this it was concluded that the reactive gas species must have been consumed before it penetrated far into the pores
