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.

Jim Bathie, VP Mining Crushers at Metso Outotec, said We are very excited about the SUPERIOR MKIII 6275UG. As a direct response to the market demand, weve designed a more compact primary gyratory crusher reducing capital expenditure that is applicable to both underground and above ground applications for the mining industry.
Nov 27, 2014 Underground mining methods mostly produce a feed that is finer than in a typical open pit mine, resulting in higher capacity through the plant. 3. Scalping. Scalping is usually recommended before a jaw crusher gyratory crushers can handle excavated ore. Primary gyratory crushers are not as sensitive to fines.

Nov 11, 2020 The crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper and the associated infrastructure therein. Minimising the need for high cost stationary grids to control topsize underground was a requisite, and the large topsize acceptance was met with the UG design.
mining - mining - Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
Feb 26, 2016 The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this service are much the same, regardless of how many crushing stages there are in the flowsheet therefore, the term primary crusher, by common usage, is applied to the crusher
