consists of squeezing pieces of rock diametrically between two hardened steel cones. The test set-up is shown in Figure 1. For these tests, rock pieces must have a length at least 1.4 times their diameter Figure 2a. The point load index, Id, is equal to where P is the load at rupture and D is the core diameter. Rock specimens break since tensile
This cost includes the power devoted to quarrying the rock, crushing it, disposal of wastes, transportation, acids, water pumping, shop facilities and other considerations. Thus, by burning three tons of coal one gets a profit, in energy, amounting to 997 or more tons of coal. In dollars and cents the picture is not as bright.
Thermal spalling drills such as jet-piercing and forced-flame drills heat rocks to 370 to 540 C 700 to 1000 F to create thermal stresses that spall the rock .These devices have limited application because most rocks will not thermally spall Maurer, 1968, 1980. Melting and vaporization drills utilize high-temperature devices such as lasers or electron beams to melt and vaporize rock .
Jun 23, 2015 The crushing pendulum is then released after striking the crushing platen and breaking the rock, the remaining energy is transferred via the rebound platen to the rebound pendulum. The horizontal distance that the rebound pendulum travels is recorded by displacement of a marker and is subsequently converted to a vertical height.
A crushing plant may include a hopper to receive the material, a jaw to break it into more manageable pieces, a cone or impact crusher to further reduce its size, a vibrating screen to sort to the required specification, and a conveyor belt with a rotating magnet to remove metal contamination such as rebar.

Rock up to 5 feet by 4 feet x 4 feet are crushed to not more than 12 inches in diameter by the primary jaw crusher. This material is further reduced in size by the secondary cone crusher. The primary crushing plant is now located in the pit just out of view in this image.
It can serve a variety of purposes, such as an indicator of how hard the rock is, or the cost of the explosives needed, or even as a guide to planning a shot. Powder factor can be expressed as a quantity of rock broken by a unit weight of explosives. Or, alternatively, it can be the amount of explosives required to break a unit measure of rock.
