Crushing Equipment Selection. In open pit quarry operations the loading of the blasted rock for transportation to the primary crusher house involves either power-shovels. Any size of primary crusher may be used for hand-loaded rock; it all depends upon how much secondary shooting, and hand sledging, the operator feels he can …

We present a methodology for addressing the problem of deciding the location of a third ore crusher to be installed at Chile's Chuquica- mata mine, the largest open pit copper mine in the world. This ap- proach evaluates a complex trade-off between minimizing operational cost and assuring production goal when the probability of equipment failure is …
This paper tries to model the production and operating cost uncertainties associated with the in-pit crusher location by using the stochastic facility location model.
Yarmuch et al. [61] developed discrete-time and continuous-time Markov chain models to evaluate alternative location configurations of crushers in an open-pit copper mine.
Ore is removed from a series of benches which are linked to the top of the pit by a 40 metre wide trench road. Each truck transports around 290 tonnes of excavated soil and ore to the top of the pit where it is stockpiled or sent to the primary crusher. The first ore from Oyu Tolgoi was mined at the open pit in April 2012.
A New Search Algorithm for Finding Candidate Crusher Locations Inside Open Pit Mines. January 2020. DOI: 10.1007/978-3-030-33954-8_2. In book: Proceedings of the 28th International Symposium on ...
This study covers an attempt to find the optimal location for primary crusher in order to support the expansion of Sungun copper mine, which is the second largest open pit mine in Iran. Recent ...
There are three main haulage systems that are used in hard rock open pit mines. These are: Conventional truck haulage Truck trolley systems In-pit crushing and conveying (IPCC) What is the mine's current haulage system? The most common mine haulage system transports all the blasted material by conventional, off-road trucks. The …
In open-pit mines, the traditional truck-based haulage system has consumed large amounts of energy in the haulage sector for many years. The use of continuous in-pit crushing and conveying (IPCC) systems is a viable option to significantly reduce energy consumption in this sector.

In-Pit Crushers; the Key to Hard-Rock Conveying. The essential task of the in-pit crusher in a belt conveyor transport system is to reduce blasted material to a conveyable size. Crushers for this purpose are almost exclusively of the low crushing ratio type (up to 1 : 10), i.e. so- called primary or pre-crushers, designed as mobile or semi ...
Cost efficiency and high reliability of In-Pit Crushing and Conveying (IPCC) system make it more appealing to be used in deeper open-pit mining activities. Determination of the optimum time and ...
Cost-efficient Transport for Open-pit Mines. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems. Mine trucks that weigh between 106 and 260 tons, and carry payloads from 136 to as much as 400 tons, transport these materials ...
In the Truck–Shovel system employed in open-pit mines, materials are moved from within the pit to external destinations, typically involving a crusher station for ore and a waste dump for discarded material.
In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due to the numerous benefits than conventional truck-and-shovel systems. However, the implementation of …

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture …
Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process …
