The bulk of the density determination method is performed in the field at the stockpile site, and consists essentially of two stages. G01N9/02- Investigating density or specific gravity of materials Analysing materials by determining density or specific gravity by measuring weight of a known volume.G01N9/24- Investigating density or specific gravity of materials Analysing materials by determining density or specific gravity by observing the transmission of wave or particle radiation through the material.G01N9/00- Investigating density or specific gravity of materials Analysing materials by determining density or specific gravity.G01N- INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)

Google Patents USRE33176E - Method for measuring density of a bulk material in a stockpile I am currently attempting to calculate an approximate measurement for the volume lost around the sides of the stockpile.USRE33176E - Method for measuring density of a bulk material in a stockpile There is lost volume on the top (from around the cones – see diagram) and around the sides of the stockpile in areas around the cones. The angle of repose (the angle that the ore settles to the horizontal) of the ore is also known, as is the maximum stockpile height.Īn ‘ideal’ stockpile would have a flat top and sides.It is demonstrated in the attached diagrams that due to the nature of cone-ply stacking, this is not the case. The stockpile has a limited width and length. The aim is to maximise the capacity of the stockpile, within a given space. I am in desperate need of some help with a materials handling problem which i am stumped on more specifically on calculating the volume of a stockpile that is built from a series of cones ('cone-ply')Ī cone-ply built stockpile is built with a series of cones (see diagram).
