Review of the operating data indicated that pebble crusher feed rate varied independently of dewatering screen oversize tonnage over the liner life. Therefore, in this study the process model was configured to allow the adjustment of the pebble crusher feed rate independently. The dewatering screen is used to wash the pebble product …

When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of …

Pebble crusher: A pebble crusher is required to process (crush) hard pebbles at lower cost than a SAG mill can accomplish. Whenever possible, a good design strategy is to design for no pebble crusher and leave the pebble crusher addition as a way to increase design throughput. The pebble crusher should never be considered as a contingency to

The below image shows a sectional view of a typical gyratory crusher. This type of machine is, by virtue of chronological priority, known as the "standard" gyratory crusher. Although it incorporates many refinements in design, it is fundamentally the same crusher that first bore the name of "gyratory"; its crushing chamber is very much the …

second trial was to compare AG with SAG, both with pebble crushing using revised feed size distributions, ball size distribution and mill trommel size. These revised conditions increased the specific throughput, but resulted in similar overall circuit power consumption. The pilot plant trials were conducted with a jaw crusher as a pebble crusher.

The main problem to be solved in the design of a pebble crusher for a semi autogenous grinding circuit is the steel removal from the crusher feed. The worn-out and broken steel balls, broken steel liners, etc. which are continuously discharged by the mill have to be removed with efficiency prior to the crusher.
