3. Check the strength of the shaft. When check the strength of the shaft, you can only check the strength of the biggest moment, and that is the movable jaw plate’s bearing. If it is smaller than the stress of the eccentric shaft, then the strength of the jaw crusher’s eccentric shaft can meet the requirement, and Not vice versa.

JAW CRUSHER. Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to

Figure 8.1 shows two basic types of jaw crushers: single toggle and double toggle. 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.

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 due to the action of a toggle plate), and the second is a

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

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn’t stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave, material is

The motor drives the belt and the pulley to move up and down the moving jaw through the eccentric axis. When the moving jaw rises, the angle between the elbow plate and the movable jaw becomes larger, thus pushing the movable jaw plate closer to the jaw plate, while the material is crushed, rubbed and rolled.
