For instance a logic was implemented that allows trucks to be re routed to a stockpile with a grade and hardness range fitting the loaded ore if the tip pocket is utilized fully In addition two methods for the grade blending were implemented Blending on the coarse ore stockpile happens according to.Storage of iron ore pellet feed fines (with 90 minimum granulometry of Kt and normal rigidity Kn make the stockpile unstable We can state that when Kn = Kt the stockpiles are stable 2) The models and all the work done show that the stockpiles are not stable The stockpiles are at times temporarily stable but even after formation these stockpiles are unstable and the particles are.
