When the material enters the impact zone of the hammer, it is crushed by the high-speed impact of the hammer and is then thrown onto the impact device installed above the rotor for secondary crushing. It then bounces back to the impact zone and is crushed again. This process repeats until the material is crushed to the desired particle size and discharged from the bottom of the machine. Adjusting the gap between the impact rack and the rotor frame can achieve the purpose of changing the particle size and shape of the material.
The working principle of an impact crusher has the advantages of high efficiency, energy-saving, and environmental friendliness. It has high crushing efficiency and can break large-sized materials into smaller particles, making it suitable for various industries. Additionally, an impact crusher has low energy consumption and noise levels, contributing to environmentally friendly production.
A large-diameter impact crusher is an efficient crushing device primarily used for crushing materials of medium hardness. Different models of large-diameter impact crushers have different processing capacities and application ranges, allowing for selection based on specific requirements.
Now let's take a look at the parameters of a large-diameter impact crusher. The parameters of a large-diameter impact crusher include rotor specifications, feed opening size, feed particle size, and output. The rotor diameter refers to the size of the rotor, with larger diameters generally indicating higher crushing efficiency. The feed opening size refers to the diameter of the opening through which the material enters the crushing chamber and is an important parameter determining the feed particle size. The feed particle size refers to the maximum size of the material, and a large-diameter impact crusher is typically capable of handling larger material sizes. The output refers to the amount of material that the large-diameter impact crusher can process per hour and is usually measured in tons.
Here are three examples of large-diameter impact crusher parameters for your reference.

Jaw crusher, impact crusher, and cone crusher are widely used in the mining and construction industries for crushing various materials. Each type of stone crusher has its unique characteristics and advantages, making them suitable for specific applications.
This article presents a comprehensive comparison between jaw crusher, impact crusher, and cone crusher, highlighting their differences in terms of structure, working principles, crushing capabilities, and applications.
Jaw Crusher: Jaw crushers have a fixed jaw plate and a movable jaw plate. The movable jaw plate moves back and forth against the fixed jaw plate, crushing the material by compressing it between the two plates.
Impact Crusher: Impact crushers consist of a rotor with hammers or blow bars that spin at high speed. When the material enters the crushing chamber, it is struck by the hammers or blow bars and thrown against the impact plates, breaking it into smaller pieces.
Cone Crusher: Cone crushers have a conical-shaped crushing chamber with a mantle and a concave. The material is fed into the chamber and crushed between the mantle and concave as the mantle gyrates within the chamber.

Jaw Crusher: Jaw crushers are commonly used for primary crushing in various industries, including mining, quarrying, and recycling.
Impact Crusher: Impact crushers are versatile and suitable for primary, secondary, and tertiary crushing. They are widely used in mining, quarrying, and construction.
Cone Crusher: Cone crushers are commonly used for secondary and tertiary crushing in applications such as quarrying, mining, and aggregate production.
Jaw Crusher: Jaw crushers are known for their high crushing efficiency and can produce a relatively coarse particle shape. They are suitable for primary crushing of hard and abrasive materials.
Impact Crusher: Impact crushers are efficient in crushing materials with high compressive strength. They produce a cubical particle shape and are suitable for secondary and tertiary crushing applications.
Cone Crusher: Cone crushers are renowned for their ability to produce a well-graded and cubical particle shape. They are suitable for secondary and tertiary crushing, offering excellent particle shape control.
Jaw crushers have a relatively lower capacity compared to cone crushers and impact crushers. They are suitable for small to medium-sized rocks and materials. The capacity of a jaw crusher is determined by the size of the feed opening and the eccentric throw of the movable jaw.
Generally speaking, impact crushers have a higher capacity compared to jaw crushers but a lower capacity compared to cone crushers. They are suitable for primary, secondary, and tertiary crushing. The capacity of an impact crusher is determined by the rotor diameter, rotor speed, and the gap between the impact plates and blow bars.
Cone crushers have a higher capacity compared to jaw crushers and impact crushers. They are designed for efficient secondary and tertiary crushing and can handle large volumes of material. The capacity of a cone crusher is determined by the closed side setting (CSS) and the size and shape of the crushing chamber.
Jaw crushers can accept larger feed sizes compared to cone crushers and impact crushers. They have a larger feed opening, which allows for the entry of larger-sized rocks and materials.
Impact crushers have a smaller feed opening compared to jaw crushers and cone crushers. They are designed to accept smaller-sized rocks and materials. The input size of an impact crusher depends on the type of rotor and the configuration of the crushing chamber.
Cone crushers can accept a wide range of feed sizes. They have a conical-shaped crushing chamber that gradually narrows as the material progresses towards the bottom. This design allows for the entry of various-sized rocks and materials.
The output size of a jaw crusher is determined by the distance between the jaws at the top and the bottom of the crushing chamber. Jaw crushers are capable of producing a relatively coarse output size. The final product size can be controlled by adjusting the gap between the jaws.
Impact crushers produce a cubical output size. The final product size is determined by the gap setting between the impact plates and blow bars, as well as the rotor speed. Impact crushers are capable of producing a range of output sizes, depending on the specific application and desired end product.
Cone crushers are known for producing a well-graded and cubical output size. The final product size is determined by the CSS and the position of the mantle in relation to the concave. Cone crushers provide excellent control over the particle shape and size distribution.
Jaw Crusher: Jaw crushers have relatively low maintenance requirements and operating costs. However, they consume more power compared to impact and cone crushers.
Impact Crusher: Impact crushers require moderate maintenance and have moderate operating costs. They are energy-efficient and offer good cost-effectiveness.
Cone Crusher: Cone crushers have higher maintenance requirements but generally lower operating costs compared to jaw and impact crushers. They are energy-efficient and can provide cost savings in the long run.
With the rise of compact concrete crushers, bucket crushers, and mini crushers, more and more contractors are considering diversifying their business to benefit from the savings from disposing of concrete, tipping fees, and the cost of virgin aggregates. The cheapest mini crusher is probably too much if the economics don’t pan out or you are not set up for crushing yet. Ultimately, depending on where you are with your business, owning a crusher, renting a crusher, or hauling the material to the dump is worthwhile.
You have realized that you waste too much money on construction & demolition waste… Congratulations, you have solved the first step of enlightenment.
Owning a crusher makes sense for many contractors. Outbound trucking costs, tipping fees, purchase of aggregates (or loss of the opportunity to sell product), and trucking costs often amount to mind-blowing numbers. When contrasting your current cost structure with paying for and operating a compact concrete crusher, many contractors find that you can realize big efficiencies and make more money.
It is not impossible, but it will be hard to justify a compact concrete crusher without the capability of stockpiling material. Without a yard, you are 100% reliant on on-site crushing jobs. Having the room to stockpile material allows you to be more flexible, take in material, and manage your materials business.
Purchasing the wrong type-crusher can lead you down a costly path. Jaw crushers and impact crushers achieve different outcomes. While jaw crushers are good for an efficient initial reduction in size, producing a 3”-6” coarse product, impact crushers are suitable for producing a higher-value finished spec product (e.g. ¾”- base material that meets DOT spec). Some finished product specs require an additional screening plant (e.g. #57 stone).
You haven't achieved anything if you can’t use or sell your finished product!
