Calculations involving Bond's work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (WiC, CWi or IWi (impact work index)).

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). The impact crusher rotor speed is determined by the linear speed needed by the plate hammer. And the linear speed

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. Typically twenty specimens are chosen to represent a sample and the
