    Pebble crushers also cause coarser AG product, which might be an issue depending on your downstream process. But you can't use pebble crushers in SAG circuits because the iron ore and steel balls will confuse the crusher tramp steel protection. Either fully autogenous with or without pebble crusher, or SAG without pebble crushing are valid.

  • Mill (grinding) - Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

    Oct 23, 2019  Robustness of the crusher: Pebble crushing is the toughest of crushing applications, so a crusher needs to be robust. Our Trio® TC series cone crusher is typically 40-50% heavier than similarly sized machines in the market and provides a superior level of protection against fatigue. When pebble crushing, weight really does matter.

  • SAG Circuit Design - Crushing, Screening Conveying ...

    A pebble crusher is the way to go for a greenfields project. SAG mill grates generally limit pebble extraction rates to around 25%, so you can't expect a throughput increase of more than 5-10% depending on the ore. To pebble crush, you need to port the grate.

  • Optimisation of autogenous grinding - ScienceDirect

    Hence, pebble crushing is used in several SAG circuits, using a magnetic separator to remove the steel prior to the pebble crusher. Pebble crushing (in both FAG and SAG circuits) can be used to maintain an optimum charge level in the mill, by varying the amount of crushing.

  • The SAG grindability index test - ScienceDirect

    The mill reportedly rotates at 70% of critical velocity (Verret et al., 2011), or 54 rpm (Gonzalez, 2000).There is controversy surrounding the mill rotational speed. The calculation of mill critical velocity (V c) is derived from the balance of gravitational force and the centrifugal force acting on a ball, and is given by Eq., after Austin and Concha (1994) (1) V c = 42.2 (D-d) where D is the ...
