A laboratory ball mill test was developed to provide a quick and simple measure of grindability. These values were then used to explore possible correlations between grindability and the chemical and physical properties of the limestones. Chemical analyses and thin section petrographic analyses were used to characterize the limestone samples.

Mar 01, 2009 1.1 These test methods cover physical testing of quicklime and hydrated lime, and of limestone not otherwise covered in ASTM standards. Note 1-Quicklime and hydrated lime have a high affinity for moisture and carbon dioxide. Caution should be taken to protect both hydrated and quicklime during sampling, storage, and testing (see Practice C 50).

Oct 04, 2012 Although established in the 1950s, the grindability test according to Zeisel is still one of the most important measurement techniques for the grindability of hard and brittle material. It is used intensively throughout the cement industry for testing clinker and slag, but also for limestone.
Chat OnlineThe 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

To determine the relative grindability of coal, i.e. whether it is easy or difficult to pulverize, the Hardgrove test is a standard method widely used (Klima, 1999). The Hard-grove grindability index (HGI) can be then estimated from the test. The higher the index is the easier the coal to be pulverized.
