Crusher is commonly used in quarrying, recycling, mining, demolition and food processing. Its job is to reduce the size of larger materials like stones and boulders and turn them into smaller particles. There are many types of crushers available for your project. Some examples include gyratory crushers, cone crushers, roll crushers, hammer crushers, impact crushers, and jaw crushers.
Before purchasing a crusher for your project, it is important to pay attention to the features and capacities of each to choose the best one for the job.
Broken application
For general applications, a primary crusher will be used to break larger pieces of rock into smaller pieces. It works by reducing the size of the material. After this, the smaller rock pieces can be further ground into finer particles using a secondary crusher.
A jaw crusher is a primary crusher suitable for crushing larger materials and breaking them into smaller pieces. Depending on your project, you can use it as is, or use a secondary crusher to reduce your stone to a smaller size. It can crush granite, basalt, ore, concrete and other hard rocks.
The impact crusher is a secondary crusher that breaks the finished product of the jaw crusher into smaller sizes. It can crush clay, limestone, coal, dolomite and other medium hardness materials.
How the Crusher Works
Jaw crushers have a V-shaped jaw into which rocks are placed. One jaw is fixed, and the other jaw moves in and out against it to squeeze the rock. Due to this compression, the stones are reduced in size and can only pass through the narrower part of the jaw when they become the proper size.
Impact crushers, as the name suggests, use the impact force inside the machine to break rocks. Material is first loaded into the opening of the chamber. Inside, a rotating blow bar constantly applies force to the rock. The impact of this force can make the rock hit the wall of the chamber, or collide with other rocks. This process reduces the size of the stones into smaller aggregates.
Overwhelming results
Different uses will also result in different finished products. Jaw crushers can crush larger rocks down to 1 to 35 cm. In contrast, impact crushers produce smaller material, ranging in size from 0.5 cm to 20 cm. Impact crushers can also produce finer, more consistent shapes than jaw crushers. More dust is also generated in the process.
Depending on your project, you may wish to combine a jaw crusher with an impact crusher. A jaw crusher is a primary crusher that reduces the size of material, but certain applications require a smaller finished product. This is where an impact crusher (a type of secondary crusher) can be used.
Crusher maintenance
Like other machinery that handles hard materials, crushers require maintenance and care. It is also subject to wear and tear due to the frequent impact and grinding of rocks and stones. To get the most out of your crusher, follow the user guide provided by your supplier.
Check the crusher frequently for jammed material. Regular cleaning will ensure it works at its best with every application.
To prevent damage, it is important to choose the best crusher for your crushing job. This ensures that the kind of material you put in it is one it can handle.
key points
Generally, crushers are used in quarrying, recycling, mining, demolition and food processing. It turns larger materials into smaller particles, such as sand.
When considering the factors between impact crushers and jaw crushers, the main difference is how they are used. The first is the primary crusher, while the latter is the secondary crusher.
Impact crushers can crush hard materials, while jaw crushers can crush brittle materials. Jaw crushers are suitable for harder rocks such as granite, basalt, ore and concrete. Impact crushers, on the other hand, are best suited for clay, limestone, coal, dolomite, and other moderately hard materials.
