Grindability refers to the ease of pulverizing a coal sample compared to certain reference coals. The standard method of coal grindability is called Hardgrove (ASTM D409), though this method does not provide reproducible and repeatable results for hard coal. Another method that can be accepted for petroleum coke is the test method ASTM D5003.

However, both the grindability of clinker and limestone were negatively affected in case of 40% limestone incorporation, and lower fineness values of limestone and clinker were measured when compared to 30% limestone replacement ratio.

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 m2/kg. The second was a breakability test which assessed the height that a

In a pilot scale trial, 50t of ladle slag was used in one pit, while limestone was used in a control pit. It was found that limestone achieve an acidity reduction of around 90%, compared to around 80% for slag. The slag has a halflife of around two years, and following the exhaustion of the slag as a neutralising material, the pit would be ...

The Hardgrove Grindability Index (HGI) is a measure of coal''s resistance to crushing. Grinding studies, and the resulting HGI, allow many different types of coal users to evaluate how coals will perform in their mills, allowing them to estimate grinding power requirements and throughput capacities.
