Impact Crushers

benefits of impact crushing

Impact crushers – like horizontal shaft impactor (HSI) and vertical shaft impactor (VSI) models – have an unfair reputation in some parts of the aggregate industry. Usually, it’s because they’re being misapplied or poorly maintained.

When utilized correctly, impact crushers are absolute rockstars! They produce some of the highest value, highest quality material in the aggregates industry.

Selecting between HSI and VSI crushers

Unlike the compression or squeezing action produced by jaws and cones, impact crushers (HSI and VSI) break rocks with rapid strikes. This action generates two primary benefits: high reduction ratio and precise product shaping.

Cubicle-shaped rocks are strong and have much greater particle-to-particle contacts, making them ideal for asphalt, concrete, limestone and other applications shown below.

What Are the Pros & Cons of Impact Crushers?

Impact crushers use impact force – as the name implies – to crush rocks and minerals into smaller sizes as opposed to pressure force used in, for example, jaw crushers.

Two types of impact crushers exist. These are the horizontal shaft impactor (HSI) and the vertical shaft impactor (VSI). HSI crushers are the more common of the two types and can be used in primary or secondary crushing applications and construction and demolition waste recycling. VSI crushers are typically used in secondary or tertiary crushing applications to produce a much finer end product.

The basic working principle of an impact crusher is that material is fed into a high-speed rotating turntable, which flings the material around at high speeds between a series of spinning hammers and the impact wall. The numerous collisions taking place inside the impact chamber causes the material to break apart. Upon reaching the specified size, the crushed material will be discharged.

Pros

Impact crushers are capable of delivering a much more homogenous, consistent and cubical end product. This makes impact crushers favourable when the final result needs to be a saleable commodity.

Moreover, impact crushers can be highly efficient. They also use comparatively low energy compared with other crushers types. Impact crushers are also quite versatile and can process a variety of different materials, including concrete, soft rock, hard rock, gravel and even asphalt.

They tend to have a fairly large feed inlet and sizeable crushing chamber and, if used with less abrasive materials, can lead to an economical and reliable crushing operation. Additionally, impact crushers have a high reduction ratio.

Cons

Impact crushers typically require more maintenance than compression style crushers – especially if crushing hard and abrasive materials. This is because the material in an impact crusher is constantly colliding within the crusher at high velocities to break the rock apart. This contributes to much wear and tear, although modern wear-resistant materials have made impact crushers more popular.

When crushing very soft materials, excess fines can be produced. This contributes to more potential dust pollution as well, which can be an occupational health and safety concern if not mitigated through the implementation of dust control measures.

What are the disadvantages of impact crusher?

Impact crushers typically require more maintenance than compression style crushers – especially if crushing hard and abrasive materials. This is because the material in an impact crusher is constantly colliding within the crusher at high velocities to break the rock apart.

How does a impact rock crusher work?

The materials are fed into the machine through a feed hopper, and then the rotor rapidly impacts the materials to break them down. The process works by the materials being crushed and then thrown against the impact plates or anvils that line the walls of the crushing chamber.

Is an impact crusher a primary crusher?

Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types.

Key Differences Between Jaw Crusher And Impact Crusher?

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.

What Are Jaw Crushers?

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.

What Are Impact Crushers?

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.

Jaw Crushers vs Impact Crushers

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:

Impact crushers are better at manipulating hard materials while jaw crushers are better at crushing softer materials.

Impact crushers produce a more uniform size while jaw crushers create a more jagged size. This makes impact crushers a great choice with projects that require certain specs on aggregate usage.

Impact crushers use hammers to crush the material while jaw crushers utilize two crushing jaws.

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.

Find The Right Crusher for Your Unique Needs

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.
