Pebble Crushing in SAG Mill Circuit
Substantial fluctuations were experienced in the circulating loads within the test circuit depending on the size of the feed reporting to the mill. S. To take advantage of periods when larger ore was available to the test circuit, the control of the feed to the mill was further changed by automating the mill feed rate based on feed size.

When pebble crushing, weight really does matter. Ability to handle variable feed: When a crusher has the capacity to handle variable feed such as that produced in most mill circuits, a surge bin is not required. Being able to dispense with a bin and feeder arrangement also saves space, which is a big plus for sites where space is at a premium.
