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.

The finger crusher reduces the lumps of sinter cake to a size smaller than 150 mm, in preparation for cooling and secondary crushing. As the sinter cake retains a temperature of about 850 degrees C upon leaving the strand, the finger crusher operates in a very hostile environment. This fact is addressed with the following design features:
