• Secondary Crushing Equipment

    2016-2-28 · The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.The term should not be used, as it sometimes is, to designate a particular type or size of Perfecting the Performance of Secondary Crushers E & MJ,2020-4-8 · Secondary applications are dependent on the primary crusher to provide a targeted feed size, so fluctuations in the run-of-mine (ROM) ore can contribute considerably. Changes in gradation (i.e., feed getting coarser or finer), hardness, moisture or, if the work index increases or decreases, can trigger adjustments in screen panels as well as
