A high-speed, gyratory, cone crusher or fine-reduction crusher in the same plant just as consistently produces material 70% of which passes a square opening test sieve, equivalent to its close-side setting. In both cases all material is reduced to a one-way dimension not exceeding these respective open and close-side settings.

The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine …
