1. Summary: Current ore processing facilities at Silvertip consist of a primary crushing plant located approximately 80 m from the main plant. Primary Crushing and Coarse Ore Storage. Run of mine (ROM) ore is delivered from underground to the ROM pad which has a storage capacity of 20,000 tonnes.
Methods used in Crushing & Screening Plants on ore range from a simple combination of a grizzly and one crusher to an elaborate arrangement in series of grizzly, jaw crusher, screens, and rolls or cone crushers.. Crushing is done underground at a few large mines. In general, the jaw crusher is the most suitable primary machine, yet many gyratories do the first breaking.
2. 3. 4. PRESS RELEASE: The new crusher features a particularly flat and robust design and high throughputs of up to 3,000 tons per hour, enabling it to process hard rock and ores efficiently and economically in underground mining operations. As the centerpiece of a mobile or semi-mobile system the eccentric roll crusher also enhances cost
crusher. Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of input material to the top size of crusher discharge.

Monorail for safe motor maintenance. Dedicated area to safely monitor and service the crusher per Metso recommendations.
The design experience included: the development of robust primary stockpiling and pebble crushing concepts; detailed review of scale-up of SAG and ball mill pilot plant data to plant scale; the selection of two 15 MW SAG mills and two 13 MW ball mills for the grinding circuit; and detailed modelling of the pyrite concentrate carbon-in-leach
In Mineral Processing Design and Operations (Second Edition), 2016. Abstract. Detail descriptions of designs are given of large gyratory crushers that are used as primary crushers to reduce the size of large run-of-mine ore pieces to acceptable sizes. Descriptions of secondary and tertiary cone crushers that usually follow gyratory crushers are also given in detail.
PRIMARY CRUSHER SELECTION CRITERIA • Will it produce the desired product size at required capacity • Will it accept the largest feed size expected • What is the capacity to handle peak loads • Will it choke or plug • Is the crusher suited to the type of crushing plant design • Is the crusher suited for underground or in-pit duty
Good geotechnical information is essential to crushing plant siting and design. Installing a primary crushing plant on solid rock reduces the cost of concrete and structural steel. Life of Mine/Expansion Plans The life of the mine is a key element in the design of any crushing plant. Short-term mine lives

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.
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
known traditional jaw crusher range that is designed for stationary as well as mobile applications (C80, C100, C3054, C120, C125, C140, C150, C160, C200). The second range is designed specifically to meet the needs of small to medium size mobile crushing (C96, C106, C116). All C Series crushers are designed to crush very hard rock.
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.
The existing crushing plant required expanding to 7Mtpa of product to produce a range of products from 300mm rock down to fine washed sands utilizing jaw and cone crushers, impactors, vibrating grizzlies, wet and dry screening, trommels and cyclones. The primary crusher was an 84 x 60 DTRB Jaw Crusher.
The jaw crusher is the first stage in the crushing and screening process, the main purpose of this stage is to crush the rock into a conveyable size. In addition to this, other tasks are also performed such as: Removal of natural fines, soil or other contaminants. Production of coarse products such as road base, sub base, ground base or similar.
underground and on the surface as part of mobile and semi-mobile systems.” One of the key advantages of the new crusher is its flat and compact design with integrated screen. It is 20 to 50% lower than conventional primary crushers. This greatly simplifies transportation, installation and maintenance below ground.
Pre-construction activities at the Kemess Underground Project (located in Northern British Columbia, Canada) started in 2018. Activities to date include: purchase of the first lateral development fleet, preliminary earthworks, construction of a water discharge system to dewater the future tailings storage facility, and construction of a water treatment plant.
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.
