    This is a "Vibra Screw" Bin Activator Size and Flow Rate Calculator Data Slide-Chart - it was used to measure volumetric material output rates for industrial screw feeders. - Same concept and use as a slide-rule but for industrial "in-the-field" on sight calculations.
    - One side is the size and flow rate calculator and the other side is the material classification, outlet sizes, and output rates charts.
    Used in the chemical catalyst industry (food additives and hygiene products)
