The SAG grindability index test - ScienceDirect

The test is a dry batch grinding test in which the mill is rotated and the sample ground until it reaches 80% passing Tyler #10 mesh, or 1.7 mm (Starkey et al., 1994). Because the time required to achieve 80% passing 1.7 mm is not known before starting the test, an initial grinding time is selected, the sample is ground then removed from the ...

Grindability | Britannica

Other articles where Grindability is discussed: coal utilization: Grindability: The grindability of a coal is a measure of its resistance to crushing. Two factors affecting grindability are the moisture and ash contents of a coal. In general, lignites and anthracites are more resistant to grinding than are bituminous coals. One commonly used method…
