Please as the pile side walls can not be trusted even If you make the trapezoid three buckets highĪnd three buckets wide the ange of repose willįorm quickly for you with no issues and it will beĮasy to measure using the formula for the volumeīut measure it from the ground using an inclinometer The trapezoid will form naturally following theĮdges of the pile to its angle of repose. Pile line and then dump in the center to fill The outside edges first following the outer Using the struck volume of the loader bucket onlyĭumping the first two buckets of material

You can build a small trapezoid with the loader using this method. No you cannot safely create a trapeziod while pushing the material up and over to create the flat top of the trapeziod. I hope yout loader operator is leaving the loader on the ground and not crawling up the pile which will cause a tip over. If the aggregate is the all same size or you have piles of the same size aggregate you can simply make a small trapezoid. Just walking by it is enought to possibly kill you or someone else. To find volumes and weights of stockpiles with other angles of repose, multiply those values in the table by the factor computed as follows.įactor= - 0.3819įIRST and foremost you cannot trust any pile at any time!!!!!!!!!!!!!!!!!!!!!! Weight (tons) = Volume(ft 3) x density (lb/ft 3) x 1 ton/200 lbĬONICAL STOCKPILE VOLUMES (37° Angle of Repose) In order to calculate the actual weight of material in the stockpile, determine the density or weight/cubic foot.

He following formula is used to calculate the volume of a stockpile if the diameter and height are known.ĭ = Diameter of the base of the cone in feet
