Major factors affecting operation of jaw crushers

Generally speaking, factors affecting jaw crushers are nip angle and number of rotation. Nip angle refers to the angle between mobile jaw and fixed jaw. According to calculation, the maximum size should be 320, while real angle is smaller than 250, generally rangs from 18 to 20. With over-big nip angle, ores in cavities may be squeezed up out ...

Tips to maximize crushing efficiency

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.
