The Bond low-energy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test. The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.

Rarely is there a relationship between the Bond ball mill work index and the Bond crushing (impact) work index. Two reasons for this are: The size range over which the two tests are valid (the ball mill test feed is about 2 mm, whereas the crushing test feed sizes are between 50 mm and 75 mm).

On the other hand, since the Bond's index is calculated based on a series of crushing and grinding tests (Bergstrom, 1985), it is more sensible to the presence of structural defects (micro cracks, fractures, cleavage and inhomogeneous…), irregular shape of specimens, …

Traumatic crush injuries are caused by high-impact forces applied to the fingers. Children frequently sustain a crush injury when a finger is slammed in a door. Heavy objects dropped on the fingers, hands caught in machinery and automobile accidents can also cause crush injuries.

Effect of Core Diameter on the Bond Impact Crushing Work Index Test - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This paper reports the effect of performing the impact test on contiguous sections of HQ diameter and NQ diameter core, exploring the hypothesis that the contiguous intervals give equivalent results in spite of the core diameter difference.

The simplest details make a huge difference when crushing, says Stephen Dobler, Construction's business line manager for crushing and screening in Canada. "I think everyone has a good grasp on how they should be feeding a crusher," Dobler says.

The impact crushing work index mainly includes rotor speed and productivity. (1) Impact Crusher Rotor Speed. The calculation formula of impact crusher rotor speed is n=60v/πD, in which v refers to the linear speed of the rotor (m/s) and D refers to the diameter of the rotor (m).
