So correct sizing of a crusher is also influenced by the actual capacity required. In many cases an oversized crusher needs to be selected to handle the lump size whilst the capacity consideration is less important This is more common in Jaw Crushers The industry standard of rating various size crushers is based on dry limestone with a loose bulk density of 1,6t/m³ or 100lbs/ft³ Factors affecting these capacities are excessive moisture, clay content, feeding method, feed gradation, bulk density and crushability 1

Using a 48 x 18 as a typical popular crusher model and set at a 25mm CSS we can read off the screen analysis table that: 100% will pass through a 40mm square opening 81% will pass through a 25mm square opening 61% will pass through a 20mm square opening 41% will pass through a 10mm square opening 16% will pass through a 5mm square opening Note: On the Osborn Hadfields and Osborn Telsmith Heavy Duty Jaw Crushers, the CSS is measured from peak to valley. The CSS on the Telsmith Standard Duty Jaw Crusher is measured from peak to peak. 2
