· Rock firmness can be evaluated via direct load testing, point load testing, Schmidt hammer testing, sound velocity testing, impact crushing testing, and other methods (Kahraman 2001). The uniaxial strength obtained via direct load testing is the most widely used firmness index in engineering. Although the use of the triaxial strength is more practical than use of the uniaxial strength, the ...

impact crushers are secondary crushers. Primary crushers reduce large mine stones into smaller sizes suitable for transport. They are large and heavy machines. On the other hand, secondary crushers have a feed size usually less than 15cm and reduce the stones to the required sizes. The different crushers are shown below: Fig : Gyratory crusher1 Fig : Jaw crusher2 Source 1, 2:
Jaw Crushers exert more crushing power and are the best choice for very hard rock like granite and abrasive rock. Secondary Crusher. A secondary crusher is one that takes crushed material out of a primary crusher and reduces the product further. An impactor or a cone crusher can be used as a secondary crusher. (68" feed size to ½" to 2" finished product). Cone Crushers are typically ...

Rock hardness is a term used in geology to denote the cohesiveness of a rock and is usually expressed as its compressive fracture strength. Terms such as hardrock and softrock are used by geologists to distinguishing between igneous/metamorphic and sedimentary rocks, respectively. These terms originated from historical mining terms, reflecting the methods needed to economically mine an ore ...
Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other reciproes. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds of materials of any hardness, as well as their lowcost operation ...
The paper presents the results of the testing of impact of rock hardness on fragmentation of rocks by means of hydraulic hammer and during crushing in jaw crusher. The testing was carried out on ...
· Impact crushers (rotary or hammer mills) have the capacity for high reduction ratios (up to 40:1), but are rarely applied to hard rock mines. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers. Hence, they should not be used in hard rock mines that normally have ores containing more than 15% silica (or any ores that are abrasive). Source: Barry ...
The rock blocks extracted by blasting which are larger than the opening of the primary crusher are usually fragmented by hydraulic hammer. The paper presents the results of the testing of impact of rock hardness on fragmentation of rocks by means of hydraulic hammer and during crushing in .
