The maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. The friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls.

For a given mill to have a combination of feed size, ball load, mill speed and % solids will represent the total load. In fact the later can be modelled as a function of the others. Additionally, as has been shown by Powell et al. (2001), ball loads high enough (over 12% as in the cases studied in this work) contribute to a significant portion ...

Despite having these methods for underflow, like what you have said, most plants determine circulating load through material balance of some sub-fraction, the water, radioactive tracers. Back to my question with a simple case, the circulating load results through sub-fraction do not match with the results using water. It's like 310% vs 700%.

A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by:

Joanne is a switch and when she is in a dominant mood, watch out. She decided that for the best effect, I should be immobilised while she tested it on me. So out came the cuffs and spreader bar. Who was I to argue, but moments later, I regretted not doing so as I was restrained and out came the ball crusher and her 2B e-stim control box.

Through proper application of the Gyradisc crusher, mill feeds of 100 percent passing 3, 4, and 6 mesh are attainable. The crushing action of the Gyradisc crusher results in circulating loads of less than 50 percent of the new feed rate when closed circulating on 3 mesh, to 150 percent when closing the circuit on 6 mesh.

Rock Crusher History. History tells us, it was in 1830, the first US patent was issued on a rock crushing machine. It covered a device which, in a crude way, incorporated the drop hammer principle later used in the famous stamp mill, whose history is so intimately linked with that of the golden age of mining. In 1840, another patent was …
