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.
