Jaw crushers use compressive force to break down large materials into smaller, more manageable pieces. It has two crushing jaws (one is stationary while the other one is moving) that produces mechanical pressure for crushing the materials. The two vertical crushing jaws create a V-shaped opening called the crushing chamber where the materials are dropped off. It’s so-called because the opening starts off wide then tapers down to a V where the crushed materials go to.
- Crushing different kinds of ore
- Reducing building rubble to pieces
- Rock ranging (from medium to extremely hard rocks)
- Breaking down large glasses
- Crushing other hard material
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.
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.
