Clinker grindability

Good Day,

is there anyway besides microscopy to measure/predict the hardness/grindability of clinker?

Hello Shastrib,

The Bond Work Index is one practical method.

Some years ago I had some grindability testing done by Magotteaux.

Two separate tests were performed, the first was the SGI test which assessed the number of
revolutions within a test mill that were required to produce a surface area of
350 m2/kg. The second was a breakability test which assessed the height that a
steel ball must be dropped from to break a clinker nodule.

I don't know if this testing is still available but it was useful when grinding a number of different imported clinkers
