What Are the Functions of the Different Parts of the Stone Crushers?

After you have gotten a brief view of the stone crusher about their types, components and other things, you may be curious about the functions of the parts of the stone crushers which are of various sizes, colors and shapes. And if you want to operate a stone crusher, you must know the functions of the parts as well as the working principles of it. So next all of this information will be introduced in details.

Let’s take the jaw crusher as an example for it is the most often seen and most widely used machine in our daily life. The functions of the parts of the stone crushers are to be discussed in the following passage.

First is flywheel. The flywheel of the Jaw crusher is to store the energy of motion and then be put into the industrial formation. It is use to standardize the industry. The flywheel is usually made up of iron or steel and the most important thing to pay attention to is to regulate the control of the static balance.

Second is the frame of the Jaw crusher. The crusher is used to support the counterforce of crushing material. It requires sufficient strength and stiffness. Usually the whole frame is made up with cast steel while smaller crushes can use cast iron to take the place of cast steel. The big crusher needs constructing segmentedly. The whole construction is very delicately.

Third one is the adjusting device. There are three types of the adjusting device: the wedge type, plate type and hydraulic type. The smaller crusher is adjusted by increasing or decreasing the number of the support of thrust plate.

Forth is the jaw plate and side plate of the jaw crusher. Jaw plate and bed consist of the fixed and the moving jaw. The jaw part is the working part and is fixed in the bed by bolts and wedges. The bed of the fixed jaw is the front wall of the rack and the bed of the moving jaw is hang and it needs sufficient strength and rigidity to bear the crushing counterforce.

Next are the transmission parts. Eccentric shaft is the centerpiece of the crusher, bearing huge bending torsion. It is manufactured by high carbon steel. The whole production must be delicately processed. And one side of the eccentric shaft is linked with the flywheel.

The final one is the lubrication device. Centralized lubrication is usually applied to the eccentric shaft. The angle of the moving jaw is very small, making it very difficult to lubricate the heart part between the shaft and the bearing.

All the parts are assembled to imitate the process of the chewing of the animals. And the maintenance of the stone crusher is of great importance. All of the parts should be replaced by the exact data of the parts to keep it in the best condition. The replacement of the thrust plate, plate, check and repair bush and other things must be checked.
