Let's follow the chain of events within a crushing cycle to see how they all go together. The first component of the crusher is the drive motor. This will drive a reducer …
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.
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.
In contrast, the single toggle jaw crusher has fewer shafts and bearings and only one toggle which goes from the bottom of the swinging jaw to a fixed point at the back of the jaw crusher. The eccentric is located at the top of the swinging jaw and is …
The fixed jaw remains stationary, while the movable jaw pivots, allowing for the material to be crushed progressively. Eccentric Shaft: The eccentric shaft is a critical part that connects the movable jaw to the rest of the crusher. It helps in the movement of the jaw and imparts an oscillating motion to it.
Technical data | Single-toggle jaw crusher Design Single-toggle jaw crushers are characterized by the swing jaw being suspended directly on the eccentric drive shaft and the lower part of the swing jaw being braced against …
The eccentric shaft is positioned behind the swing jaw, and the toggle plates connect the lower part of the swing jaw to the drive mechanism. As the eccentric shaft rotates, it drives the toggle plates to move, creating a powerful crushing action as the angle between the two toggles becomes more acute.
Jaw breakers use an eccentric shaft to make the jaw move an inch and a half, at around 400 rpm. That makes 1500 engine rpm with a 540 rpm PTO. So i dont know if it will be direct drive with just a torsion damper to get maximum fuel efficiency, or with a 1:1.25 reduction so the tractor engine can run at 1900 to 2000 rpm to get more power.
In general, primary crushing in mining is best conducted with gyratory crushers, jaw crushers or the eccentric roll crusher whereas the later crushing stages are the operation areas of cone crushers. Of course, our thyssenkrupp Crusher experts will happily help you to define the best crusher solution for your operations.
The single-toggle jaw crusher features a pitman mounted on an eccentric shaft at the top. At the bottom of the assembly, the pitman is held in position by a toggle plate. The combination of eccentric motion at the top and rocking motion at the bottom provides a positive downward thrust throughout the crushing chamber.

The common wearing parts of jaw crusher mainly include movable jaw plate, fixed jaw plate, side(liner) plate, eccentric shaft, toggle plate(bracket), bearing, and so ...
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: Features …
Flywheel hubs of our jaw crushers are equipped with special locking assembly which connects flywheels to the eccentric shaft. This system ensures that the flywheel is held safely and tightly on the shaft.
The moving jaw closes against a stationary jaw with sufficient force to fracture material, usually rock of some type. This crushing action is accomplished as a result of eccentric motion developed by a pitman, or eccentric shaft. Motor power is applied to the crusher drive shaft, which in turn transfers rotation to the eccentric shaft.
The single-toggle jaw crusher features a moving jaw suspended on the eccentric shaft. It's known for its efficiency in crushing but tends to be more susceptible to wear because of the high motion of the jaw.
From the welded steel base to the rugged eccentric shaft, Minyu Jaw Crushers are built with brute strength and quality bearings. …
Figure 2 depicts the working mechanism of the jaw crusher with clearance in the revolute joint, which includes frame 0, eccentric shaft 1, moveable jaw 2, and elbow plate 3. The driving part is the eccentric shaft 1, which provides power to the moveable jaw 2 via the revolute joint A to accomplish the crushing operation.
Previous dynamic studies of the complex pendulum jaw crusher neglected the bearing clearance between the eccentric shaft and the moving jaw, which is crucial for analyzing the effect of bearing clearance on the dynamic performance of the crusher. By employing the Lagrange multiplier method, a dynamic model considering the bearing clearance of …
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: Features a swing jaw suspended on the eccentric shaft, enabling a lighter, more compact design with high capacity.
The motor drives eccentric shaft through pulley, and transmits the eccentric rotation of eccentric shaft to outer moving jaw through side plate, thus causing the periodic swing of the moving jaw. The materials falling into crushing chamber composed of moving jaw and fixed jaw are crushed by extrusion, splitting, and bending, and then discharged ...

Eccentric Shaft. The moveable jaw is attached to the eccentric shaft and is where the energy is generated. Also called the pitman, the eccentric shaft is rotated by the flywheel that pulls the arm up and causes the toggle plates to move. This forces the swing jaw to be pushed outwards towards the stationary jaw, crushing the materials.
