Feed Lump Size mm Feed Analysis Size - mm - mm - mm - mm % Passing % % % % Product Size Req d mm COMPILED BY NOTES All the parameters referred to above must still take into consideration the actual capacity of the crusher at required settings as the cavity has a volumetric constraint. 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

3 Osborn Hadfields Single Toggle - Heavy Duty For material below 500 MPa. Hadfields Single Toggle - Heavy Duty Current Model Optional Model Optional sizes available to suit feed/setting ratios. Assists with finer wear, nip angles and in some cases provides smaller closed-side settings. Performance Schedule SIZE OF FEED OPENING CLOSED SIDE SETTING & CAPACITY (Depending on material type) x to 245mm x mm x to to 1 220mm Screen Analysis PRODUCT SIZE CLOSED SIDE SETTING OF CRUSHER Information for reading screen analysis To illustrate the approximate screen analysis from an Osborn Hadfields Heavy Duty Jaw Crusher, the following results can be read from the relevant table. 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
