Rock crushing is an integral part of the construction industry. Creating specific types of aggregate is an essential step in nearly every project, and the machines that complete these tasks are vital to overall success. Understanding the different types of rock crushers ensures that your teams have the best chance at success by understanding what sets them apart.

When it comes to crushing rocks, there are two main crushers: jaw crushers and impact crushers. Both have their own unique advantages and disadvantages, which is why it can be difficult to decide which type of crusher is right for the job. Read on to learn the key differences between the two and which one is right for your project's needs.
A jaw crusher uses two metal plates to disintegrate rocks. It is one of the oldest types, and it is still widely used today because it is reliable and affordable. Jaw crushers are often used in mines, quarries, and construction sites.
Jaw crushers are typically used as the primary smasher. They are preferred for their ability to demolish tough, abrasive materials. Jaw crushers are usually configured with a stationary jaw and a moving jaw. The moving jaw closes against the stationary jaw to accomplish its mission. The size of the crushed material is determined by the gap between the jaws.
There are a few different types of jaw crushers, such as the simple jaw crusher, the compound jaw crusher, the hammer crusher, the impact crusher, and so on. The main difference between the simple jaw and the compound jaw crusher is that the former has only one movable jaw plate while the latter has two movable plates. The movable jaw plates of the compound jaw crusher can move in an elliptical motion, which helps to crush the materials more efficiently. The hammer crusher pounds materials by hitting them with hammers, while the impact crusher does this by hitting them with high-speed particles.
Impact crushers are a different version of jaw crushers that are chosen for their improved strength and durability.
Impact crushers use force rather than pressure to break up materials. Then, that material is fed into the machine and smashed between two plates. The force of the impact breaks the material apart, and the pieces are then ejected from the machine. Impact crushers tend to be more efficient than jaw crushers, and they can produce a higher-quality, finer product. However, they are also more expensive to operate.
Impact crushers and jaw crushers are two of the most commonly used types. They both use compression to break down materials, but they use different mechanisms to do so. An impact crusher uses the force of impact to break down materials, while a jaw crusher uses the force of compression to do so.
There are several factors to consider when comparing jaw and impact crushers, including the type and size of materials and the desired output. Jaw crushers are typically used for harder materials such as granite and basalt, while impact crushers are more suited for softer materials like limestone and sandstone.
The main differences include:
Overall, impact crushers are better with hard materials while jaw crushers are better suited for more brittle materials. Impact crushers are also better at processing larger pieces of material while jaw crushers are more efficient at crushing smaller pieces.
When choosing between these two pieces, also keep in mind that jaw crushers are the more affordable of these two pieces of equipment.
There is no one-size-fits-all answer to the question of the best type of crusher, as the best one for a given application will depend on a number of factors, including the type and size of the material to be crushed, the intended output size, and your overall budget. However, jaw crushers are often considered a better overall choice in general than impact crushers, as they can typically handle a wider range of materials, are cheaper, and produce a more consistent end product.
The type of crusher you choose for your project depends on a variety of factors, including the type of material you need to crush and the size of the pieces you need to produce. Some crushers are better suited for softer materials, such as limestone, while others are more effective for harder materials, such as granite.
It's important to find the right crusher for your needs, as each has its own advantages and disadvantages. To learn more about which crusher is the right fit for your project, reach out to Mellott's team of dedicated experts today at 888-801-.
Jaw crusher and impact crusher are both frequent used crushing equipment in the market. But many people may have a limited understanding of them, especially those who are new to this industry. Here are the differences between jaw crusher and impact crusher in practical applications.
1)material hardness
Jaw crusher is suitable for crushing various soft and hard materials with compressive strength between 300-350Mpa. The models and specifications of ZENITH jaw crushers are all complete. There are coarse jaw crusher and fine jaw crusher for customers to choose, mainly used for the primary crushing operation of materials.
Impact crusher is suitable for crushing materials with medium& soft hardness and small brittleness, such as limestone. If the materials are hard, they can cause significant damage to wear-resistant parts and shorten their service life.
Impact crusher is widely used in all kinds of coarse, medium and fine crushing operations, the discharge port can adjust the particle size arbitrarily, in order to meet the needs of different customers.

2) material particle size
Jaw crusher is generally used for crushing large materials smaller than mm (depending on the equipment model). It has wide application in mines and sand and gravel production lines.
Impact crusher is used to process small and medium-sized materials.
The obvious difference between jaw crusher and impact crusher is the difference in structure and working principle. The working mode of jaw crusher is a curved extrusion type, and the material is crushed by compression in the crushing chamber composed of a moving jaw and a fixed jaw.
Impact crusher adopts impact crushing principle, where the material is repeatedly impacted and crushed between the rotor (plate hammer) and the impact plate.
As we know, in crushing, sand making, beneficiation and other production lines, jaw crusher is the most commonly used primary crushing equipment for coarse crushing.
Impact crusher is generally used as secondary or tertiary crushing equipment for medium and fine crushing. Sometimes, impact crusher can also be used as coarse crushing equipment when the raw material is soft or has low hardness.
Jaw crusher and impact crusher have different production capacities.
The max production capacity of ZENITH C6X series jaw crusher can reach to t/h.
The max production capacity of ZENITH CI5X series impact crusher can reach to t/h.
Of course, there are also many other types of jaw crusher and impact crusher for customers to choose. They have different production capacities, meeting different production requirements of customers.
Jaw crusher, as coarse crushing equipment, has larger discharge fineness, usually below 300-350mm (depending on the model).
Impact crusher, as medium or fine crushing equipment, naturally has smaller discharge fineness.
Here, we should notice that due to different material properties, the discharge fineness will also be different.
The grain shape of products from jaw crusher is not ideal and there is high content of needle-like particles. Impact crusher is a product in the crushing equipment that has good discharge grain shape and fewer edges of the final product, and its particle size is also better than cone crusher.
Therefore, in actual production, we often adopt impact crusher after jaw crusher for shaping.
Generally speaking, many manufacturers have higher sales and transaction volumes of jaw crusher due to price. Secondly, jaw crusher is more traditional crushing equipment that can meet users' application requirements in terms of performance, quality, power consumption, and other aspects. This cost-effective device is more likely to attract users' attention.
When selecting crushing equipment, we should choose the proper jaw crusher or impact crusher according to production requirements in order to achieve ideal production capacity and benefits.
