When used underground, jaw crushers are commonly used in open circuit. This is followed by further size reduction in crushers located on the surface. When the run of mine product is conveyed directly from the mine to the crusher, the feed to the primary crusher passes under a magnet to remove tramp steel collected during the mining operation.
GRINDABILITY TESTS Bond Rod mill work Index The rod mill work Index is also normally distributed with and average and median of 14.8kWht It is common to observe difference between the ball and rod mill caused by variation in ore hardness The test has been mainly used for the design of rod mill or primary ball mills. http

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
