calculation of nip angle of crusher

Roll Crusher

Unless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 are rare, a flowsheet may require coarse crushing rolls to be followed by fine rolls.

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. The nip angle gets flatter as the machine is set ...

Solutions To Improve The Production Capacity Of Jaw Crusher

 · According to calculation, the max nip angle can reach to 32°, but in the actual production, the nip angle is generally between 18°-20°, smaller than 25°. If the nip angle is too large, the raw materials in crushing cavity will be squeezed out of the cavity, which may hurt operators or damage other auxiliary equipment.
