## How To Calculate Crushing Work Index

2021-9-18 How To Calculate Crushing Work Index. A routine to calculate the wear part consumption of the crushers was also implemented this estimates the crushing chamber life thereby allowing the wear part cost to be determined the installed cone crushers were equipped with a control system to compensate for the effect of mantle wear.

2021-9-20 The paper by Angove Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5. The laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the 22.4 value I calculated, so what you are observing is probably the natural variation in the crushing test.
