The trajectory of the ore as it leaves the conveyor belt will determine where in the bin or pile each size of the crushed ore will land. Once in the bin, another stage of classification takes place. The smaller ore due to its lesser size and weight, tends to filter downwards faster than the coarse material does.
Blending on the coarse ore stockpile happens according to a user-specified recipe. In other words, the user specifies a percentage for each pile that is converted into a rate at which the pile is drawn down. This allows balancing out periods of low or high grade by blending in stocked ore.
