Pre-concentrate Mill Feed based on Size while rocks are

If an individual particle sorting route is suitable then conventional compression crushers may be acceptable as such sorters have an economic bottom size 'cut-off' of (perhaps) 10 mm and crushing to (say) 25 or 30 mm may produce only a reasonable proportion of < 10 mm.

Optimise your pebble crushing with HPGR

 · When pebbles comprise a large proportion of a (S)AG mill’s feed as they’re returned multiple times, the proportion of large particles which have the power to crush with the force of their impact is reduced and new particles are instead subjected to additional attrition and abrasion. This can over-grind fines, producing unsuitable ultra-fines.

The pre-crushing stage has reduced the proportion of -100mm to + 40mm intermediate size fraction from 30% to 20%. Feed size distribution to the SAG mill (stream 8) as a function screen size .

Tips for maintaining efficiency in crushing circuits – Quarry

 · The finer the CSS, the greater the proportion of fines produced. The CSS of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large an angle causes boiling in the crushing chamber; this is where the jaw plates cannot grip onto the rock and it keeps slipping up and down, avoiding being crushed.
