May 13, 2019· 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 is set ...
Mar 02, 2021· In most cases, cone crushers provide reduction ratios (the ratio of the feed size to the crusher vs. the size of the crusher discharge) of 4-to-1 up to 6-to-1.
