Jaw Crushers | McLanahan

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material. A toggle plate and tension rods

“Computer Aided Design of Jaw crusher”

crushers have the square opening design, and secondary jaw crushers have rectangular opening design. Jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock. They follow “crush using compression” mechanism.

Primary Crusher

Surge bins precede the primary crusher to receive dumped loads from ships or trucks and should have enough storage capacity to maintain a steady feed to the crusher. In most mills the crushing plant does not run for 24 h a day, as hoisting and transport of ore is usually carried out on two shifts only, the other shift being used for drilling and blasting.

Jaw Crusher Working Principle

The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain. As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particle’s weight and the

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
