Here is what a well choke fed jaw crusher looks like! Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the jaw's cavity full to maximize rock-on-rock compression and crushing.
Jaw Crusher Working Principle
Slippage occurs in all crushers, even in ideal conditions. Only the particle's weight and the friction between it and the crusher surfaces counteract this tendency. In particular, very hard rock tends to slip upward rather than break. Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed.
