The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers. The open and closed sized settings for given product sizes can also be determined. The test requires at least 10 particles of -75 +50 mm
view moreSizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond's Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed. A crude test

view moreAggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more
view moreImpact crushing is basically like opening a walnut with a hammer – when the hammer meets the shell, the nut instantly cracks into a number of smaller pieces. Mining equipment creates impacts by using a rotor to violently hit and throw rock against the walls of a crushing chamber. As a kind of basic first rule you could say: Impact crushing is suitable for rocks with a low work index (<12) as
