Note: Crusher output gradations and tons per hour products may change due to variations in operating conditions and application of the crushing equipment. This information does not constitute an expressed or implied warranty or guarantee, but shows results of test crushing of samples provided by customers. This is guideline information.

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 in uenced 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/m or 100lbs/ft Factors affecting these capacities are excessive moisture, clay content, feeding method, feed gradation, bulk density and crushability

Information for reading screen analysisTo 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 10mmsquare 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 Std Heavy Duty Jaw Crusher is measured from peak to peak.

How to determine maximum feed for a 3042 Jaw Crusher

Crusher Gape (smallest dimension of the feed opening)

30 (760 mm)

Maximum Feed

= 30 (760 mm) x 0.8

= 24 (600 mm)

30 760 mm

600 mm

TOP

Settings in above case is as follows

600 mm Lump 6 = 100 CSS (F:CSS) 6 : 1

Yield 600 mm Lump 4 = 150 mm Product Lump (F : P) 4 : 1

When setting below this ratio effective manganese wear increases

This condition will also occur when too large a crusher is used with small feed size.

Only the extreme ends of the liners are used

6

Nip Angle

Nip Angle is the angle created between the fixed and swing jaw liners.

Range 11- 23 optimal 19 for most material types

Maximum nip angle occurs at minimum discharge setting with curved liners

Discharge setting usually expressed as closed side peak to valley or peak to peak dimension
