Jaw Crusher Working Principle
Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. Anything that reduces friction, such as spray water or feed moisture, will promote slippage. Leading a jaw crusher

Optimal feed arrangement
Choke feeding. The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure peaks and improving overall performance.

Cone Crusher Liners: How to Select and When to Change
The best way to ensure optimal liner life is to choke feed your Cone Crusher. Choke feeding allows a full chamber with material on top to help force the material in the chamber through. Choke feeding also minimizes the air pockets in the crushing chamber to reduce the creation of flat, elongated particles. Preventative maintenance and documentation

Tips for maintaining efficiency in crushing circuits
Try to choke-feed any compression-type crusher. Remember, we are using gravity and the weight of the material to push or force material through the chamber. Since in a compression machine the material breaks to fill the air pockets or voids in the chamber, a non-choke chamber will produce a slabbier output than a choke-fed chamber.

Best Practices for Feeding Jaw Crushers
Jaw Crushers should only be fed in line with some type of Feeder or scalping screen. This means the discharge end of the feeding machine should line up with the feed opening (or gape, the opening as measured from jaw die to jaw die) of the Jaw Crusher. In-line feeding limits opportunities for the material to clog the Jaw Crusher. 2. Choke feeding
