Rock breakage by crushing, blasting, and drilling ...
An objective of most rock blasting is to produce the maximum rock breakage for the minimum expenditure of energy. A buried explosive charge produces a detonation wave that causes a com- pressive shock wave in the surrounding rock, and the explosive gases tend to enlarge the cavity by crushing and compaction of the rock.

Rock breakage by crushing, blasting, and drilling ...
The fundamental principles of rock fragmentation by crushing, blasting, and drilling are not well understood; however, empirical observations have provided means for predicting the energy requirements for these processes. Experimental procedures and methods of analysis used in comminution studies are described in this review.

2015-4-1 2015-4-1 The rock breakage threshold force for fracture ranged from 10 5 N for the top size to 10 9 N for the bottom size. The minimum breakage fragment resolved in the simulation was 2.5 mm. The breakage force for the top size is lower than for the gyratory crusher because smaller particles have a lower force requirement for breakage, decreasing in proportion to their mass (but possibly

2012-8-16 crushers are typically of the square opening design, and secondary jaw crushers are of the rectangular opening design. However, there are many exceptions to this general rule. A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the
