The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers
crushing plant’s structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize these structural and construction costs to suit the life of the operation. Perhaps a steel-supported, modular design will be best for short-term operations,
Jaw gyratory crusher for underground iron ore mining and the crushing chamber of a BK 63-75 in a stationary copper ore plant Jaw gyratory crusher with specially designed feed opening Fields of application • Coarse feed material • Block cave mining • Underground mining 6 Gyratory crushers 7
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 large topsize acceptance was met with the UG design.
crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant: process design, equipment selection, and layout.
design, construct and test a modular underground processing plant (the ‘Python’) that is compact enough to operate underground yet sufficiently efficient to achieve highly economic, if not optimum, recoveries. The Python consists of the following key connecting components: coarse and fine crushing, screening, gravity and/or
Excavating for and assembling a primary crushing plant underground is complicated and costly. The planning process requires careful consideration of the following steps: 1. Capacity. The required capacity determines the type of equipment required and also the number of parallel crushers needed to fulfil the production rate.
Vinci is carrying out detailed design in the design-build contract. The project work is scheduled to take 40 months. The enlargement includes a new underground primary crushing plant

The key concepts in the design of Python underground processing plant are described below. COMMINUTION To achieve a low profile / low power consumption process route for the Python many issues were taken into account. Perhaps the most significant is the utilisation of a 2 stage crushing system to achieve a final crush size of P 80
Multi-discipline Design/Build team creates new primary crusher dump wall at underground sand mine Related Projects AIL Mining was recently involved in a multi-party Design/Build effort on a new primary crusher dump wall for Pattison Sand Company in Iowa.
Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.
The one step that has not been addressed is the primary crusher. This paper will address the opportunities for comminution improvement through optimisation of the primary crusher.

The term “primary crusher,” by definition, might embrace any type and size of crushing machine. 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

Above 1000 tph primary gyratory crushers begin to look interesting, and after the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.
In the primary crushing stage, the ore is normally crushed as soon as possible after its arrival. Many underground mines have primary crushers underground to reduce ore size and improve hoisting efficiency. Skips, trucks, and other handling vehicles are intermittent in arrival, whereas the crushing section, once started, calls for steady feed.
4. Outotec has signed an agreement with Chilean mining operator Codelco to design and supply a Foresight semi-mobile primary gyratory (SMPG) crushing plant for the Radomiro Tomic mine. The company said the Foresight SMPG, equipped with a Superior MKIII 60-110 primary gyratory crusher, apron feeder discharge and dust collection, would meet
From the underground crusher, ore will be transported to the crushed-ore stockpile on the surface using a 3-km-long conventional conveyor system in two segments.” Yamana added: “Using a conveyor rather than diesel trucks to transport ore to surface reduces CO2 emissions by 2,233 t/y, equivalent to taking 500 cars off the road.
