PEF Jaw Crusher

Jaw crusher is one crushing machine with extensive application, and can be classified into PEF compound pendulum jaw crusher and PEJ simple pendulum jaw crusher.

Generally speaking, PEF compound pendulum crusher is suitable for coarse and intermediate crushing of various ores and rocks with compression strength of 250MPa or below, three types of crushers above PEF0609 are able to crush various hard ores and rocks. PEF-X compound pendulum jaw crusher is typically suitable for fine crushing of ores and rocks with intermediate hardness, while simple pendulum jaw crusher is able to crush ores and rocks differently in hardness, and is especially suitable for crushing various hard and strong-corrosive rock materials.

PEF Jaw crusher working principle

A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw, called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap.
