Material classification code chart
A very fine 100 mesh material with an average density of 800 kg/m3, that has average flowability and is moderately abrasive, would have a material code 800A10036. If this material were very dusty and mildly corrosive the number would then be 800A10036LT. This consists of the average density, the usual size designation, the flowability number, the abrasive number followed by those material characteristics which are termed conveyability hazards. The Material code is used in the horsepower formula to determine the horsepower to operate a screw conveyor. The calculation of horsepower is described here.
