Jaw crushers come in different shapes and sizes to fit different crushing needs. Some of the most common types of jaw crushers used today are single-toggle jaw crushers and double-toggle jaw crushers.
In single-toggle jaw crushers, the moving crusher operates in an elliptical pattern while in double-toggle jaw crushers, a pendulum motion is utilized in order to crush hard materials. The crushing force is generated by the eccentric shaft which is then transferred to the crushing zone by a toggle plate system. Spring pulling rods provide non-positive connection throughout the whole system and heavy loads are compensated by the centrifugal masses on the eccentric shaft.
Because of the angle of deep between the two crushers, the fed material can be reduced significantly upon entering the crushing chamber. The adjustable crusher settings and the suitability of the chosen tooth form for the crushing plates will determine the final size grain distribution of the crushed materials. An adjustable wedge system allows for multiple adjustments of the crusher settings. All parts of the adjusting system can be easily accessed and requires little to no maintenance. The parts can also be replaced in the event that it completely wears out. More details, we could study this artical: How to adjust jaw crusher gap?
All of the toggle plates used in jaw crushers use replaceable temperature pressure bars that are maintenance-free. A lubrication system is used to ensure adequate grease supply to the bearing points.
