Crushers are commonly used in quarrying, recycling, mining, demolition, and food processing. Its job is to reduce the size of larger materials such as stones and boulders and turn them into smaller particles. There are many types of crushers available for your project. Some examples include the gyratory crusher, cone crusher, roll crusher, hammer mill, impact crusher, and jaw crusher.

Before you buy a crusher for your project it is important to note the characteristics and capacity of each one to choose the best fit for the job. In this post, we take a look at the similarities and differences between an impact crusher vs a jaw crusher. If you’re interested in these machines, read on!


Crushing Applications

Crushing Applications

When it comes to general applications, a primary crusher will be used to break bigger pieces of rocks into smaller chunks. Its function is to reduce the size of a material. After this, a secondary crusher may be used to further grind the smaller chunks of rock into finer granules.

A jaw crusher is a primary crusher that is suitable for breaking bigger materials and turning them into smaller pieces. Depending on your project you can use it as it is or use a secondary crusher to turn your stones into even smaller sizes. It can crush hard stones such as granite, basalt, ores, and concrete.

An impact crusher is a secondary crusher that can turn the finished product of your jaw crusher into even smaller sizes. It can crush clay, limestone, coal, dolomite, and other medium-hardness materials.


How the Crushers Work

A jaw crusher has a v-shaped jaw where the rocks are put into. One jaw is fixed while the other moves in and out against it to squeeze the rocks. The stones are reduced in size due to this compression action and can only pass through the narrower part of the jaw if they turn into the right size.

An impact crusher, from its name, works by taking advantage of the impact inside the machine to crush rocks. The materials are first loaded to the opening of the chamber. Inside, a rotating blow bar exerts force to the rocks continuously. The impact of this force can make the rocks hit the walls of the chamber, or collide with other rocks. This process reduces the size of the stones to smaller aggregates.


Crushing Results

Crushing Results

The difference in use will also result in different finished products. A jaw crusher reduces the size of bigger rocks to sizes of 1 to 35 centimeters. In contrast, an impact crusher produces smaller materials that result in sizes of half a centimeter to 20 centimeters. Impact crushers can also bring out finer and more consistent shapes than a jaw crusher. It also produces more dust in the process.

Depending on your project you may want to combine the use of a jaw crusher and an impact crusher. A jaw crusher is a primary crusher that can reduce the size of your materials but some fields of application require a smaller finished product. This is where an impact crusher, which is a secondary crusher, can be used.


Crusher Maintenance

Crushers, like other pieces of machinery that deals with hard materials, require maintenance and care. Because of the frequent impact and grinding of rocks and stones, it can also undergo wear and tear. To make the most of your crusher follow the user guide given by your supplier.

Frequently inspect your crusher for stuck materials. Regular cleaning can ensure that it will work in tiptop shape for every application.

To prevent damage, it is important to choose the crusher that best fits your crushing job. This ensures that the kind of material you put into it is something that it can handle.


Key Takeaway

In general, crushers are used in quarrying, recycling, mining, demolition, and food processing. It turns larger materials into smaller particles such as sand.

When it comes to considerations between impact crusher vs jaw crusher, the main difference is how they are used. The first one is a primary crusher while the latter is a secondary crusher.

An impact crusher can crush hard materials while a jaw crusher can crush brittle ones. A jaw crusher is suitable to use for harder rocks such as granite, basalt, ores, and concrete. On the other hand, an impact crusher will work best with clay, limestone, coal, dolomite, and other medium-hardness materials.
