Jaw Crusher Operate And Replacement Parts

JAW CRUSHER: THE JAW CRUSHER PARTS AND THEIR PERFORMANCE.

Introduction

Jaw crushers are one of the main used types of crushers. It can be defined as a crusher that uses a lot of force used to compress rocks like heavy rocks using its two jars. These are referred to as jaw crusher because they have jaws. The two types of jaws are very important and vital to this crusher. These include fixed and moving jaws among other important parts. The jaw crusher is mainly used as a primary crusher and later a secondary crusher. It is a primary crusher because it has the ability to reduce the huge rocks into smaller particles. Unlike other types of crushers, the jaw crusher is able to receive hard and heavy rocks.

The jaw crusher is great at breaking huge rocks into smaller particles. It is best known for handling coarse materials like basalt and granite. It is used for activities like mining, road building and construction. The jaw crusher has its merits which make it usable. These merits include:-

• It is simple to manage to make production effective. It is easy to operate and manage in terms of maintenance.
• Ability to handle tough materials. The rocks are very heavy but can be managed by the jaw crusher. It has an extraordinary capacity to break the huge rocks into stone particles in equal sizes.

How does the jaw crusher operate?

The rock material is placed into the machine. The movable jaw which is flexible compresses the stone onto the fixed jaw. It exerts pressure on the rock until broken into pieces. The process is repeated until the stone is finely broken down. It is only produced when desired rock particles are produced evenly. When the rock material is broken into particles, it is discharged through the crusher’s bottom.

The purpose of this article is to provide detailed information about the jaw crusher parts. The aim of this section is to therefore cover the different parts and their uses.

1. The jaws. The jaws of the jaw crusher are very vital to ensure effective performance. Both of these jaws are composed of manganese steel. The two kinds of jaws help to break the heavy hard rock into smaller pieces. They ensure that no rock particles are produced until finely broken into the desired pieces. The jaw crusher consists of two types of jaws namely the movable and fixed jaw.

The movable jaw or swinging jaw. This jaw type is flexible and has the capacity to move back and forth. Its flexible ability is attributed to the eccentric shaft. It has reciprocating movements that help in crushing the rock against the fixed jaw. During the crushing period, it compresses the rock against the fixed jaw. This causes the rock to crush into smaller particles.

The fixed jaw. It is also referred to as the vertical jaw. It is stationary and forms the crushing chamber. It is used to crush the rock into particles.

2. The toggle plate. The toggle plate is found at the bottom of the movable jaw. The toggle plate also helps the crusher generate the energy required to crush the rock. It provides protection to the crusher by preventing entry of any unwanted or uncrushable rock materials. The toggle plate can be compared to a fuse. Because it breaks when uncrushable material is introduced into the machine.
3. Flywheel. The flywheel generates energy used for the effective operation of the machine. It provides the energy from the time rock material is introduced to when particles are discharged.
4. Eccentric shaft. The shaft controls the movement of the movable jaw.
5. Pitman bearings. The pitman is found at the upper part of the jaw crusher. These provide support to the movable jaws.

Conclusion

While choosing a crusher, you need to know for what purpose you wish to use it. The jaw crusher provides is best for the hard rocks. It is good for its efficiency in breaking the hard rocks into small rock particles. The jaw crusher is best for hard rock breaking compared to the other crushers.
