Working Of Impact Crusher . Bond Impact Crushing Work Index Procedure and Tabl. Sizing 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 Bonds Third Theory of Comminution, the work energy input is proportional to the new crack tip length .
Aggregate Crushing Value Test
Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.
Use of rock mechanical properties to predict the Bond ...
· The crushing energy in mineral processing industry is usually determined by empirical Bond's index, regardless of the mechanical properties of a rock. Although several attempts have been made to obtain the comminution energy based on theoretical approaches, it would be appropriate to examine this relation based on physical concept.
