In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock geometallurgyto be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant platesurface. Less abrasive and softer rocks or stones are crushed by impact and shear but also compressive mechanisms.Get A Quote
After the mine has blasted the ore, the first reason why we crush rock is really to be able to transport it onto the next same. Conveyors and transfer chutes are limited in sie and I say AMEN to that as if you are left to the mining engineers, they8217d blast and send 608243 rock to the SAG mill.
Since each sie reduction stages of crushing is limited to around 6-to-1 average, you need to blast as fine as possible to minimie the number of stages in crushing and crushers needed to reduce the run-of-mine8217s hard-rock most economically as you can. Typical hard-rock crusherslike jaw, gyratory and cones break rock by nipping the ore between a fixedstationary and a moveable wear-resistant surfaceliner.
How much reduction each crushing stage is capable of infliction of rocks reduction ratio is driven by the angles between the 2 surfaces on each side and holding the rocks-to-be-crushed as the move towards and away from each other.
Too large an angle will not grip the rock presented, while to small an angle will reduce the use of the potential sie reduction that8217s available to the operator. As gravity pulls the rock down from the top of the crushing chamber feed to the discharge close-side-setting, all rocks undergo multiple impacts causing them to get crushed.
To feed a rod andor ball milling circuit, you need to crush as follow.
Crushers for large giant process plants gt2,000 to 200,000 TPD using semi-autogenous mills only requireprimary crushingand are selected as well as designed based on.
Common work index terms you need to review and understand as they relate to crushing.
The Ai Abrasion Index measures the abrasivity of rocks during its crushing. There are several ways or test methods at your disposition to obtain this number including theAngeles Abrasion Testand the Deval Abrasion test.
The most common abrasion test however, is the Bond method where a 76x25x6mm 3x1x0.258243 piece of 500 Brinell SAE 4325 chrome-nickel-molybdenum steel rotates in a falling stream of rocks under standard predetermined conditions to measure its weight loss. The resulting Ai is used to predict crusher liner wear rates.
