A flywheel stores the energy of the jaw crusher during the empty stroke and then releases it at the right moment in order to crush the material. This helps to create a uniform load energy so that energy is conserved. In fact, there are two flywheels on a jaw crusher, one that connects the V-belt to the eccentric shaft to transmit kinetic energy.

Typically, jaw crushers produce less fine material than impact crushers. The reduction ratio of a jaw is approx. 4 to 1. Fines are necessary to meet certain gradations and increase material compaction. This is the reason why a jaw crusher is predominenatly used as a primary crusher for an intial reduction in size or to produce a non-spec material.

In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.
In this type of crusher, the swing jaw is suspended on the eccentric shaft, which allows for a more compact design compared to other jaw crusher types. The single toggle jaw crusher has a simple structure, low cost, and easy maintenance.
Universal Jaw Crusher: This type has a "V"-aligned fixed jaw and a movable jaw on an eccentric shaft, creating an elliptical motion. Overhead Eccentric Jaw Crusher: …
Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. ... 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.
The fixed jaw of a jaw crusher acts as a sturdy frame, while the movable jaw exerts force on the rock by pressing it against the fixed jaw. The crushing action is achieved through the movement of the eccentric shaft, which causes the movable jaw to …
A hydraulic jaw crusher is a type of jaw crusher that uses hydraulic pressure to crush materials. It has a movable jaw that is operated by an eccentric shaft, as well as a fixed jaw that is positioned opposite the movable jaw. The hydraulic system allows the jaw to open and close, providing a wider range of crushing settings.
Jaw Crusher Eccentric Shaft Crusher Spare Parts GTEK. Jaw Crusher Eccentric Shaft is installed on the top of the jaw crusher. It runs through the movable jaw, pulley and flywheel.
By removing the moving jaw suspension shaft and the front toggle plate of simple pendulum jaw crusher, and suspending the moving jaw on eccentric shaft to combine the connecting rod and the moving jaw into whole, a compound pendulum jaw crusher takes shape, which is characterized by simple structure, reliable movement, …
The movable jaw, which is supported from the top by an eccentric shaft, is connected to the tension arm and an angled built-in support plate that absorbs the cyclic loads in the lat section. ... Jaw crushers are used as the primary crushers in the first stage of a crushing process for the breaking of large-sized rocks, while jaw crushers with ...
Mastering jaw crusher maintenance skills is benefit to improve machine life span as well as production. here you will learn how to change jaw plates, repair and maintain other important parts.
In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an ...
Pitman is the main component of a jaw crusher that forms the moving part of the crusher. It functions as the link between the stationary and the moving jaw. The pitman is responsible for transferring the motion of the eccentric shaft to the rest of the crusher components, such as the toggle plate and the swing jaw.
The oscillating member is supported on an eccentric shaft that rotates at half of the crankshaft speed in the same direction and is driven by the crankshaft. The oscillating member, eccentric shaft and crankshaft jointly impact the piston movement and give rise to a shorter intake and compression stroke than a long expansion and exhaust stroke.
The foundation of a jaw crusher is the frame, which provides structural support and houses the eccentric shaft, which is a critical component for generating crushing motion. Eccentric Shaft:
