why eccentric shaft is used in jaw crusher

On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double roll spherical roller bearings. The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side (called a stationary jaw die

Jaw Crushers. Jaw Crushers are used to reduce the size of many different types of materials in many applications. The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. Read More

why C Series jaw crushers have a large eccentric throw coupled with a steep toggle plate angle that magnifies the effective stroke at the crusher discharge. The large stroke, combined with the right speed, fly-wheel inertia and high vailable crusher power result in truly high crusher perform-ance. Operation at small settings as well as

A critical point in the operation of large jaw crushers is the arrangement of the swing jaw and its supporting shaft. While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is used—shaft is clamped in frame and jaw swings on the shaft! Another point has been lubrication

Jaw crushers work according to the principle of pressure reduction. The crushing of the crushed material takes place in the wedge-shaped shaft between the fixed and the eccentric shaft moving crushing jaw. Due to the elliptical movement process, the crushed material is crushed and transported downwards. This process will be done by using the

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

In a typical jaw crusher, two outer bearings located on either side of the main frame support an eccentric shaft, while two inner bearings support a movable jaw. These are commonly known as “Pitman” bearings. The reciprocating motion of the shaft moves the Pitman against a second, stationary jaw. As material reaches the bottom of the chamber, it fractures
