A single blast can break approximately 45,000 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 begins. Venetia mine is an example of open-pit mining. In underground mining, miners tunnel into the earth’s crust through the kimberlite pipe. Tunnels are constructed on two levels about 25m vertically
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 begins. The Kimberley Big Hole is an example of open-pit mining. In underground mining, miners tunnel through Earth’s crust to the kimberlite pipe. Tunnels are constructed in two levels, one above the other with
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. 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.
Primary crusher installed at diamond-mine. A multidisciplinary engineer- ing and project manage- ment company based in Edenvale, on the East Rand, Senet, was awarded the contract in 2004 for the
Nov 10, 2020· Metso Outotec is launching an extension to it’s primary gyratory crusher range: The SUPERIOR™ MKIII 6275UG. The new crusher, which can be used in different types of applications, provides large capacity with significant savings in CAPEX and operating costs.
Dec 18, 2019· How you select the best primary crusher from all of the available primary crushers is required a great deal of design based on the mining plan and operation input. Usually, capacity, feed size, product size, rock compressive strength, abrasion index and mobility of crusher are considering as criteria, and in practice usage, gyratory, double toggle jaw crusher, single toggle jaw crusher, high
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 are much the same, regardless of how many

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.
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6
Geologists do this by following the trail of secondary diamond sources (e.g. river beds) to determine where the primary sources of pipe deposits are. Once the pipes are found, ore samples are examined to evaluate suitability and profitability in mining.

Oct 28, 2019· Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds. Miners build walls or divert rivers to expose the diamond-bearing dry river or ocean bed.

Diamond recovery at Ekati mine. In the process plant, a gyratory primary crusher reduces the ore to -300mm, coarse ore being stockpiled in a 20,000t storage building. A hot water-flushed cone crusher reduces the ore to 75mm before a high-pressure roll crusher reduces it to minus 25mm.
Stone crusher is crushing machinery that used to reduce the size of minerals to obtain the required ore particles. According to the characteristics of the rock crushers can be divided into the primary, secondary, tertiary, and fine crusher. The common crushing equipment is jaw crusher, impact crusher, cone crusher, hammer crusher, roller crusher, gyratory crusher, etc.

A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap
The average quarry does not produce as much on this undersize rock as the average mine, but the usual practice in mining operations is to scalp off most of the undersize ahead of the primary crusher.For example, jaw crusher usually is used as primary crusher.
Primary crushing plants are the first step in material processing and/or link between mining truck and belt conveyor, train or road. TAKRAF’s range of primary crushing plants Primary crushing plants can be equipped with gyratory crushers, jaw crushers, twin-shaft sizers, double-roll crushers, impact crushers or hammer crushers, depending on
13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.
These crushers are a proven first stage of compression crushing for Large Mines and Quarries. Mined ore or quarried rock can processed down to a size suitable for the secondary crushers.
