Estimating bulk density of compacted grains in storage ...
Jan 07, 2013· One particular property that affects the estimation of mass in bulk storage is the accuracy of estimation of average-specific weight (bulk density or test weight) within the storage bins. Estimation of mass based on laboratory measurement data of bulk density and the storage volume results in a gross underestimation.

Polypropylene Silo Capacity - Ineos
Average Bulk Density of PP = 32 - 38 lbs. / ft3; Long term storage in silos can lead to compaction that will affectively raise the bulk density. For conservative estimates use an average of 35 lb. /ft3; for compacted silos, use an average of 37 lb. /ft3 or consult an INEOS O&P Technical Service professional. Examples: 9’ Diameter, 45o Cone Silo
