1. To improve the nip angle (by decreasing the nip angle) when crushing slippery or round material (material that is difficult to bite). 2. To increase the length of the crushing zone (and thus increase the life of the jaw dies) when the feed material is consistently smaller than the crusher's input capacity.
The heavy duty machines use in the first mechanical stage of comminution are mainly jaw crushers. The distinctive feature of t his class of crusher is the two plates which open and shut like animal Jaws (Grieco and Grieco, 1985), this jaw is called jaw crusher plate. The crusher jaws are set at an acute angle such that one jaw is pivoted and the other jaw is fixed.
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 ...
