Crusher Work Index Hardness Classification

Sizing a crusher can be done reliably calculated thanks to the ImpactCrushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According toBonds Third Theory of Comminution, the workenergy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product 8211 the feed.

    A crude test procedure description of this Crushability test follows in that rock samples smaller than 75 mm but greater than 50 mm are placed 2 8220hammers8221 of 13.6 kg each and mounted to swing on bicycle wheels. Both hammers of the 8220pendulum8221 will impact the smallest measured side on the rock. The hammers are set to fall again from a higher drop position to input enough energy to break the rock. This is done 10 times to obtain 10 breaks and the WI kWht 53.49 x Impact Crushing Strength Specific Gravity of the sample. jktech.com.au.
