A jaw crusher is utilized in many different industries, such as building and demolition, recycling, mining, and quarrying. Also, you can use it for asphalt manufacturing, etc. Industry professionals process large feed sizes via it. Moreover, it is to take less wear from rough material.
There are two jaw plates of a jaw crusher; one is fixed, and the other is mobile. These plates are what give it its distinctive appearance. Together, they form a chamber in a V shape through which materials fall, and it crushes repeatedly. Although they might be smooth, these crusher jaw plates typically have a wavy appearance.
In this blog article, we will discuss what a jaw crusher is and what its purpose is. We are also going to discuss its benefits and disadvantages.
How Does It Work?
When you enter some material in the chamber, the moving jaw compresses towards the stationary jaw. It crushes the rock between its massive plates. The composition of the stone breaks apart by squeezing it repeatedly.
It falls into the chamber as it gets smaller and smaller. A predetermined crushing size in the chamber’s bottom controls the final output size.

The processing of aggregate minerals, RAP, and recycled concrete with rebar, to mention a few applications, calls for the use of a variety of crushers. This includes hammermills, impactors, and cone crushers.
Impact or compression are the two methods of crushing. Impactors and hammer mills employ an impact force, whereas jaw crushers and cone crushers use a compression force.
Advantages of using a Jaw Crushing Equipment
- High Reduction Ratio: Jaw crushers have a high reduction ratio. This allows them to process larger pieces of material while still producing output that is finer. Hence, they are perfect for primary crushing.
- High Productivity: A big crushing chamber and a strong motor provide jaw crushers with a reputation for high productivity. They can quickly and effectively process a variety of materials.
- Flexibility: Jaw crushers are adaptable equipment that you may use for a wide range of applications. This includes crushing hard rock to recycling concrete and asphalt. They can work with a variety of materials.
- Simple Structure: Jaw crushers have a straightforward design. This makes them simple to maintain and fix. Because maintenance activities are frequently simple, it also increases the downtime.
- Robust Design: Jaw crushers are common to construct hard frames and long-lasting parts. This ensures a lengthy lifespan even in difficult operating circumstances.
- Economical: These crushers are a popular option for many applications due to the fact that they are frequently more affordable than other types of crushers.
Disadvantages of Jaw Crusher
- Size Restrictions: The size of the feed material that jaw crushers can process has limitations. Moreover, it may diminish the crusher’s capacity or even damage it if the feed material is excessively big. It can also cause blockages.
- Noise and Vibration: Jaw crushers can produce noise and vibrations, both of which can be problematic. This particularly happens in urban or residential areas.
- Maintenance: Although they are relatively simple to maintain. However, jaw crushers need routine care and attention to ensure ideal operation. Breakdowns may result from careless maintenance.
- Dust Emission: Using jaw crushers to crush materials can produce a lot of dust. Also, it can be hazardous to the environment and the health of workers. You may require measures to manage the dust.
- Energy Consumption: Jaw crushers need a lot of energy. It is particularly required when starting up and crushing heavy materials. Higher operating costs could be the effect of this.
- Restrictive Mobility: Jaw crushers are typically stationary equipment that is difficult to move from one place to another. In some situations, this restriction could be a hassle.
- Effect on Jaw Plates: As a result of wear and tear over time, it may become necessary to replace the jaw plates that crush the material. This also raises the maintenance expenses.
Applications Of Jaw Crusher
Jaw crusher equipment is commonly used worldwide for a wide variety of applications. It is effective to use for crushing hard rocks in industrial settings. Get an affordable Jaw crusher machine manufacturer and buy affordable jaw crushers.
According to the desired material size, crushing is typically done in three phases.
Primary Crushing
The crushing process starts with this stage. The feed material’s size is typically between 800 and 1500 mm. It lowers down between 150 and 300 mm.
Secondary Crushing
This is the second crushing stage. The first crushing operation reduces the rock or ore’s feed size. Also, it ranges from 150 to 300 mm, down between 50 and 80 mm.
Tertiary Crushing
The third stage of crushing is this. The secondary crushing process reduces the size of the ore or rock. This type of crushing ranges from 50 to 80 mm to 5 to 12 mm.
Conclusion:
In summary, jaw crushers have a number of benefits, such as high reduction ratios, productivity, and adaptability. However, they also have some drawbacks, such as restrictions on handling large materials.
It also includes noise, vibration, upkeep requirements, and probable dust emissions. When deciding whether to utilize a jaw crusher. It is important to take into account the unique requirements and limitations of the application to assess if its benefits outweigh its drawbacks.
