Clinker Grindability Page 1 Of 3

Nov 04, 2013 re Clinker grindability. 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 m2kg. The second was a breakability test which assessed the height that a

Grindability An Overview Sciencedirect Topics

The grindability test ASTM D409, ISO 5074 uses a ball-and-ring type of mill in which a sample of closely sized coal is ground for a specified number usually, 60 of revolutions. Then the ground product is sieved and the grindability index is calculated from the amount of undersize produced using a calibration chart. The results are converted ...
