· The 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.

· There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary-all of which have their own unique benefits.

Crusher Sizing • Jaw crushers are sized on the basis of the maximum particle size to be crushed or the tonnage rate to be crushed. • Maximum particle size should not exceed 80% of the gape. • For example, a 400- by 600-mm crusher will accept a maximum lump size of 400 by 0.8 = 320mm.

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.
