dense phase conveying system calculation

Here are the steps to calculate a dense phase conveying system: Determine the bulk density of the material you want to convey. Bulk density is the weight of the material per unit volume. It is typically expressed in pounds per cubic foot (lb/ft3) or kilograms per cubic meter (kg/m3). You can find this information in the material safety data ...
