Crushing in Mineral Processing

Dec 26, 2015The Compressive Strength of rocks is measured by crushing cylinder shaped (drill core) ore samples of 2″ x 2″ (51mm X 51mm). This techniques allows for a rock-to-rock relative comparison. The Bond’ Crushing Work Index is common to calculate the power needed to crush rocks from a given F80 size to a resulted P80 product size.
