jaw crushers reduce large rocks or ore by means of compression. mechanical pressure is applied using the crushers two jaw; one is fixed while the other makes an eccentric movement. there are also primary and secondary types of these crushers.the tighter the setting, the smaller the output size and the lower the throughput capacity. As a compression crusher, jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages.the secondary crusher is mainly used to reclaim the primary crusher product. the crushed material, which is around cm in diameter obtained from the ore storage, is disposed as the final crusher product. the size is usually between 0.5 and cm in diameter so that it is suitable for grinding. secondary crushers are comparatively lighter in for finer crushing or reduction a symons cone crusher the norm. symons are commonly used for secondary, tertiary or quaternary crushing. they do this by a different chamber design which is flatter and by operating at about twice the rotational speed of a primary type gyratory crusher. one of the first cone crushers had a direct drive vertical motor mounted above the spider with the drive shaft aug 03, 2012 the completion of the secondary crusher is an important moment in the move towards the end of the canadian malartic ramp up phase. about osisko mining corporation osisko mining corporation operates the canadian malartic gold mine in malartic, quebec and is pursuing exploration on a number of properties, including the hammond reef gold project the temporary crusher was successful at increasing the throughput by and based on the operating data, plans are currently being developed to install a permanent secondary crushing system in front of the sag mill. this paper will review the results from the test crusher and the flow sheet for the permanent secondary crusher.
