What is a jaw crusher?
The jaw crusher is actually one of the most basic crushing equipments used for sand production, which causes crushing and creation of small pieces of stone by continuous wear operation. The most important part used in the structure of an industrial jaw crusher is its jaw, which is made of manganese steel to resist erosion and continuous wear with stone pieces.
The jaw crusher mechanism is simpler compared to other crushers, and it is only by placing the large pieces of rock between two fixed and moving plates that the crushing process takes place. The important thing about the industrial jaw crusher is its production in different dimensions and with different jaw opening sizes, which makes it possible to crush stone pieces with different dimensions.

How Jaw Crusher works
The jaw crusher, as the first crushing device in the process of sand production, has two resistant jaws, one of which is fixed and the other is movable, and they are located at the bottom of the entrance opening. The jaw crusher works in such a way that the fixed jaw is placed in place And with the movement of the movable jaw towards the fixed jaw, the incoming large stones are crushed. Until the crushed stones reach the desired size, the pieces of stone remain inside the crusher and are turned into smaller pieces by two jaws. The jaw crusher machine has different sizes based on the dimensions of its inlet opening. Therefore, when buying this type of stone crusher, we must consider the size of the desired input stone pieces and choose the right product based on that.

Introduction of jaw crusher types
In general, jaw crushers are classified into various types based on their specifications and application, the most important and common of which are as follows:
Double Toggle Jaw Crusher (Double Toggle Jaw Crusher)
In this model of jaw crushers, two mobile jaws are used to crush the mine pieces, and the required force is provided by two oscillators. Since the double-arm jaw crusher has higher strength and strength than the single-arm type, the maintenance of this device requires more care and attention. The double-arm jaw crusher is used to crush very hard and large pieces of stone.
Overhead Eccentric Jaw Crusher (Overhead Eccentric Jaw Crusher)
In this type of stone crusher, the movable axis is located in the upper part of the jaw, and the oscillating movement of the jaw takes place in the up and down direction. The type of design of this jaw crusher model makes it suitable for crushing large stone pieces
Jaw crusher with hydraulic adjustment system
This model of stone crusher jaw device provides the user with a hydraulic system to adjust the distance between the jaws.
Advanced jaw crusher with electronic control

Familiarity with jaw crusher parts and their use
The jaw crusher machine is made by connecting various parts, each of which plays a vital role in the process of crushing primary parts. Among the most important components of the jaw crusher, the following can be mentioned:
- Main Frame: The main frame is actually one of the parts of the jaw crusher, this frame is made of hardened steel and it is used to keep other parts of the crusher together.
- Strong fixed jaw (Fixed Jaw Plate): One of the two crushing plates in the crusher is a jaw that is fixed and helps the crushing process.
- Moving Jaw Plate (Moving Jaw Plate): It is a moving part that with the help of its oscillation, the rocks between this part and the fixed jaw are crushed.
- Eccentric Shaft (Eccentric Shaft): This piece is in the form of a metal shaft that is responsible for moving the movable jaw. Since the eccentric axis is required to continuously press the movable jaw, in order to increase the strength of this part, its material is considered to be made of resistant steel.
- Bearings (Bearings): Bearings are actually one of the jaw crusher components that, in addition to maintaining and stabilizing the eccentric axis, also help the smooth operation of this device.
- Feeding System (Feeding System): It is a vital part of the jaw crusher which is responsible for guiding the raw materials into the machine.
- Discharge Setting (Discharge Setting): The output settings section allows the user to adjust the size of the stones discharged from the crusher.
- Strong adjustment springs (Tension Rods and Springs): with the help of these types of springs, the necessary pressure is provided to stabilize the mobile jaw in place.
- Flywheel (Flywheel): Strong Flywheel is a type of high weight wheel that balances the rotational and oscillating movement of the engine and thus causes uniform movement of the mobile jaw.
- Drive System (Drive System): The flywheel system is one of the components of the jaw crusher, which is actually a type of electric motor that rotates the eccentric axis conveyor belts.
- Handles and bases (Toggle Plate And Seats): Handles and bases are considered among other important parts for moving the movable jaw in its axis.
- Types of guards: Guards are used to protect users from the internal components of the jaw crusher and reduce the possibility of injury.

Which technical specifications of a jaw crusher should we consider when buying?
In general, there are 10 important technical characteristics that should be considered when buying a jaw crusher in order to get the best output from it.
1. Shrinkage capacity
It is equal to the maximum amount of raw materials in tons that the jaw crusher can process every hour. Usually, depending on the type and model of the jaw crusher, its capacity can reach six thousand tons per hour.
2. Dimensions of the entrance opening
The dimensions of the entrance opening of the jaw crusher are determined in terms of length and width in millimeters or inches, and according to that, the maximum size of stones entering the machine can be determined.
3. Output size
It represents the minimum and maximum possible dimensions for crushed stone produced by a jaw crusher, which can be easily adjusted.
4. Jaw type
One of the most important features to consider when buying a jaw crusher is the material of the jaw used in it, which is usually cast iron or steel. If using a jaw crusher to crush minerals with a high degree of hardness, it is recommended to use a device equipped with a steel jaw.
5. Reduction ratio
The crushing ratio in the jaw crusher shows the difference in the size of the input and output parts. The higher this ratio is, the crusher has a higher ability to crush raw materials.
6. Propulsion system
The drive system can be electric or hydraulic, and its choice depends on the type of industry.
7. Energy consumption
One of the important factors that must be considered when choosing a jaw crusher is the amount of energy consumed by the device, which is expressed in watts, and if it is not optimal, it can cause the user to face huge costs.
8. Jaw adjustment system
With the help of this system, the distance between the jaws can be adjusted and in this way, the size of the outgoing stones can be determined.
9. The immune system
Since maintaining people’s health in the workplace is of great importance, the presence of safety equipment such as safety keys, safety pedals and guards in the jaw crusher is one of the things that must be checked before buying the device.
10. Weight of the device
Since the overall weight of the crusher has a significant impact on how to carry it, choosing a device with the right weight can make it easier to move and reduce costs.

The capacity of the jaw crusher depends on what factors?
The meaning of the capacity of the stone crusher is the amount of parts output from the machine in tons, which depends on various factors. One of the influencing factors in the capacity of the jaw crusher is the distance between the opening and the throat of the jaw crusher. If we can see the internal constituent parts of the jaw crusher, we will notice the distance between the two jaws of the machine, which decreases as we go down. The upper part of this distance is called the opening of the jaw crusher, and the lower part is also called the throat of the jaw crusher. The larger the opening of the jaw crusher, the greater the input of the device, and as a result, the output of the device increases. Of course, it should be noted that the distance of the bottleneck should not be less than a certain limit. However, by reducing the distance between the jaw crusher’s throat, the pieces of stone remain between the two jaws for a longer period of time and are crushed more. The engine bearing should also be increased.
Another effective factor in the capacity of the jaw crusher is the speed of the moving jaw. Increasing the speed of the moving jaw can improve the capacity of the device. Of course, it should be noted that this increase in speed will improve the capacity up to a certain period, and after that the capacity will remain constant. It should also be mentioned that if we intend to increase the capacity of the stone crusher by increasing the speed of the mobile jaw, we must first change the distance between the jaws and the weight of the jaw according to our needs.
Jaw crusher maintenance
In general, the jaw crusher can be repaired easily and at a low cost due to its easily replaceable parts. Also, if you observe the basic points of maintenance of the device, which include timely lubrication, not inserting stones with dimensions larger than the entrance opening and avoiding too small the throat, it is possible to increase the life of the device and reduce the costs. Repairs and maintenance helped.
