DrillingForGas.com Mechanisms of rock cutting
Crushing bits work by crushing the rock to make an indentation with a tooth and then scouring the rock away with the subsequent tooth movement. The harder the rock the smaller the indentations and the slower the drill rate per revolution. ... Improved understanding of the detailed mechanisms of rock cutting/breaking, post yield failure ...
Figure 6.11 shows a rock crushing mechanism. It is used in
Figure 6.11 shows a rock-crushing mechanism. It is used in a machine where large rock is placed in a vertical hopper and falls into this crushing chamber. Properly sized aggregate, which passes through a sieve, is discharged at the bottom. Rock not passing through the sieve is reintroduced into this crushing chamber.

Prediction Model of Drilling Performance for Percussive
A drill bit motion model was developed to represent the dynamics of a drill bit impacted by a dropped piston and explain the impact stress propagation and rock-crushing mechanism. The rock-crushing effect of the drill button bit was measured through a piston drop test.
How to Choose a Rock Crusher Sepro Aggregates
Not every rock crusher is right for every application. When choosing the best crusher for your aggregates operation, it’s critical to understand the different mechanisms by which rock crushers work and the effect this has on efficiency, operation costs, and the final product.. One of Sepro’s aggregate experts, Dave Phelan, explains in more detail in the video below.

Chipping and crushing mechanisms in orthogonal rock
Dec 01, 2016 The rock removal mechanism in the rock cutting process includes crushing and chipping failure modes. Crushed and powdery chips are attributed to the crushing mode while chunk-like chips are formed due to the chipping mode. Chipping of rock has been concluded to be caused by either tensile or shear stresses by different researchers.
Crushing Principles of Mechanical Crushing
Optimization of a Final Crushing Stage This method applies to other crushers where a control variable is available The crushers are the last size reduction stage in the value chain. Over crushing is common. The connection between crusher setting and yield is often unknown The rock cannot be repaired. We need to control the crusher
