About this site

Oct 07, 2019  In a Hardgrove test, samples are crushed to a specified size, air-dried, and weighed, then run through a laboratory grinding (milling) machine for 60 grinds (rotations). The milled sample is then placed on a sieve of set specifications. The amount of sample that passes through the sieve is used to calculate the Hardgrove grindability index.
