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.
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.

Mar 01, 2000· The results of Bond grindability tests are given in Fig. 3.It is clear from Fig. 3 that, as expected, grindability of slag is lower than clinker, i.e., it is more resistant to grinding. A more interesting point highlighted in the results is the change of grindability with the amount of slag added to the mixture.

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 half-life of around two years, and following the exhaustion of the slag as a neutralising material, the pit would be ...
