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 vs. Impact Crusher vs. Cone Crusher




1. Structure And Working Principle

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.




2. Application Range

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.

3. Crushing Efficiency And Particle Shape

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.




4. Capacity

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.




5. Input Size

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.




6. Output Size

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.




7. Maintenance And Operating Costs

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.




Jaw crushers, impact crushers, and cone crushers have distinct characteristics andadvantages that make them suitable for different crushing applications. Jaw crushers excel in primary crushing of hard and abrasive materials, while impact crushers are efficient in secondary and tertiary crushing, offering a cubical particle shape. Cone crushers provide excellent particle shape control and are suitable for secondary and tertiary crushing.
