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.
Crushing The crusher consists of a 1,400 mm x 2,100 mm, 600 kW gyratory crusher. The crusher is designed for 220 t mine haul trucks to dump directly into the crusher feed pocket. Two dump positions on opposite sides of the crusher allow for simultaneous dumping. The capacity of the dump pocket is 330 t or approximately 1.5 trucks.

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.
We have completed expansion of DOZ production capacity to 50,000 tons/day with a second crusher and additional ventilation, as well as accelerated certain developments, for a cost of approximately US $60 million. We anticipate increasing production to 80,000 tons/day. This increase would speed up recovery of high-grade ore from underground mining.

After 2004, when the DOZ mine averaged 43,600tpd, a second underground crusher and additional ventilation were installed to increase daily capacity to 50,000 tonnes. Ramp-up production has begun at the Deep Mill Level Zone (DMLZ) underground mine, which lies below the DOZ underground mine and to the east of the Grasberg ore body.

Mining operations use different kinds of crushers so selecting the appropriate crusher is important for every operation. Understanding the stages of crushing process and the types of crushers that best fit each stage can simplifies your equipment selection. Each type of crusher is different and used to achieve a certain end result.
1) Crusher capacity calculated based on a typical run-of-mine feed material with an average raw density 2.8 t/m and max. feed size ≤ 80 % of crusher feed opening. Actual values are depending on feed material characteristics (e.g. hardness UCS, …
Jan 22, 2021 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. Minimizing the need for high cost stationary grids to control topsize underground was a requisite, and the topsize acceptance was met with the UG design.
Nov 10, 2020 The 6275UG crusher's feed opening is 15% larger than in similar crushers, while also reaching up to 30% more capacity than comparable crushers. The company also said in the MKIII UG, downtime can be reduced by up to 70% thanks to concave replacements with another Metso Outotec proprietary innovation, the Rotable Topshell.

Feb 26, 2016 Underground mining operations without surge capacity ahead of the primary should be figured for at least 25% reserve. The average gravel plant usually has some surge capacity between the pit and the primary crusher; in many instances, however, this surge is so small that it cannot be counted on to smooth out protracted delays in the pit.

May 11, 2017 Traffic and blasting considerations limit minimum distances to around 250 feet, so the maximum desired distance becomes about 650 feet, and the moveup distance is 400 feet. Very wide panels may require two crushers, thus minimizing haulage distance to the flanks, and allowing one crusher to operate while the other is moved.
