· In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to 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 wearresistant plate/surface.

Mining3 developed the Oscillating Disc Cutter, which was licensed in 2006 by Joy Global (now Mining Corp) and rebranded as DynaCut™. With relatively low input power, the DynaCut cutting technology – now incorporated into 's DynaMiner machine – enables continuous, or semicontinuous mining of hard rock in both surface and underground appliions.
· Particularly in hard rock mining, rock mechanics are of vital importance because all the plans and activities deal with rock and rock masses. To generate an appropriate mine design and plan for a certain mineral deposit, collecting geological data and estimating basic characteristics of the rock masses are fundamental requirements.
· Typical hardrock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wearresistant surface/liner. 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 rockstobecrushed as the move towards and away from each .

UNDERGROUND WORKS IN HARD ROCK TUNNELLING AND MINING P. K. Kaiser1 Diederichs2, C. D. Martin3, J. Sharp4, and W. Steiner5 ABSTRACT The rock mass around an underground opening is subjected to a unique stress path that results in low radial confinement and both tangential loading and unloading conditions near the wall.
Crushing, sizing, milling, breaking technology for every appliion. Raw materials are so diverse. Even within a single mine or quarry you could be dealing with an extreme range: hard to soft, dry to sticky. Your crushing and sizing solutions need to be able to cope with whatever you throw at them – reliably, and in good time.
History. The VCR mining method was developed by INCO and CIL Inc., and is based on Mr. Livingston's crater blasting theories. It was first used in 1974, at the Levack mine loed in the Sudbury Basin's North Range, and it provided productivity benefits almost fact, mining productivity, measured in pounds of nickel and copper produced per manshift, has improved by ...

· In hardrock appliions the designer may favour a design that incorporates more crushing upstream of an HPGR (highpressure grinding roll) circuit for energy efficiency. In cases where there are a lot of clays present or there is high moisture, an AG (autogenous grinding) or SAG (semiautogenous grinding) mill may be appropriate.

Rolls Crushers. MACSALAB Rolls Crushers are designed for secondary reduction after jaw crushing. These smooth roll crushers will rapidly reduce coal, ore and hard rock from a maximum feed size of 20mm to fine sand. Ruggedly constructed easy to operate. Breakage of material is by nipping action with minimal fines generated.
· Stemming. In this video Anthony Konya of explains stemming and stemming calculations. Stemming is a material that is put inside of a blast hole to help prevent gases from escaping. While stemming is typically put in the top of a blast hole, it can also be used to help bridge mud seams or weak layers.
