Eccentric shaft function. Jaw crusher eccentric shaft plays an quite important role in jaw crusher operating. The pitman is put in motion by the oscillation of an eccentric lobe on a shaft that goes through the pitman's entire length. This force is also put on the shaft itself so they are constructed with large dimensions and of hardened steel.

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 ...

This force is also put on the shaft itself so they are constructed with large dimensions and of hardened steel.
The eccentric shaft is driven by a V-belt drive, with the inertia of two flywheels mounted on to the shaft accumulating crushing energy (see fig. 2). The kinematic principle applied in the ERC ensures the stroke remains the same throughout the entire crushing chamber.
Jaw crusher is one of the important crushing equipment in mining industry. It has the incomparable advantage of stable and reliable operation, easy maintenance, long service life, less dust and noise. Eccentric shaft, the main drive part plays an important role in the operation process.
Single-toggle jaw crushers – design and operating principle 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 crusher frame by means of a toggle plate.
CMS Cepcor™ Quality engineer completes the inspection of a new eccentric shaft to suit a Kue-Ken double toggle jaw crusher (models 104-120s) using one of our...
A shaft is usually longish bit of rotating machinery, made to transfer rotating power. Eccentric means off-center. Either the shaft isn't round, or it's not mounted at the center of wherever it it.
Calculate the required crusher set to satisfy the crusher throughput. 5.12. A long shaft suspended spindle gyratory crusher 12.7 cm × 127 cm was commissioned to crush limestone with a work index of 13.2 kWh/t. The crusher was adjusted to a throw of 0.7 cm and the set at 2.54 cm. The average size distribution was

The coarse particles are transferred into the crushing chamber.
travel of the eccentric when the crusher is empty and in the opposite direction when the crusher is working. The older long-shaft gyratory crusher which has the gear above the eccentric (Fig. 23) has another difference in that the eccentric bearing is supported by a bottom plate A.
The twin-jaw crusher (Fig. 2) has the second swing jaw instead of the stationary one and is mirror aligned to and synchronized with the first jaw. In the pitman-type crusher (Fig. 3), the movable jaw 3 is swung on an axle 16, whereas the eccentric shaft …
A variable throw eccentric cone crusher (10). The cone crusher (10) comprises a frame (14), a crusher head (30) supported on the frame (14) for gyration about a first axis, a bowl (54) supported on the frame (14) in spaced relation to the crusher head (30), and a mechanism on the frame (14) for varying the eccentricity of the gyration of the crusher head (30).

CG800i crushers offer excellent reliability and safer & faster maintenance – up to 30% faster than competing crushers. A robustly designed one-piece main shaft and reinforced shells are made for tough use.
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 …

Answer: The jaw crusher has the advantages of simple structure, reliable work, convenient maintenance and repair, and low production cost. It has a wide range of applications in the mining industry. The operation and maintenance of the jaw crusher is very important. (1) Preparation before operat...
The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. The chewing movement, which causes compression at both material intake and discharge, gives the single toggle jaw better capacity, compared to a double toggle jaw of similar size. 's jaw crushers are all ...
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 ...
