Bond Grindability Test Procedure
2015616 Bond Grindability Test Procedure. The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured.

BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stagecrushed to ½” (12.5mm) and the test is run under a 100% circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14mesh (1.18mm) sieve is typically used.
