The figures areprovided for estimating required screen areas and tertiary crushingequipment when used with the expected tonnage of crusher throughput.Values will differ with each specific crushing application, so thesefigures are not guarantees. Factors that can affect output gradationinclude: Feed gradation, feed tonnage, feed friability, impeller tableconfiguration, impeller speed, moisture content, closed circuit screencloth opening, available screen area and horsepower.76
