A primary crusher is a machine that breaks down large rocks and stones into smaller particles for further processing. It is the first stage in the crushing process and is essential in the mining and construction industry. The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation.

Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
