let's get to know jaw crushers and cone crushers first.

Jaw crushers: The first choice for primary crushing

The jaw crusher is popular because it crushes big rocks into smaller sizes easily. Thus, it proves itself as an effective primary crusher in aggregate, mining, recycling, and concrete industries.

It can handle very soft to very hard materials and has no abrasion limit.

If you want to crush big rocks, but you do not need the rocks to be too small or in perfect cubicle shape, a jaw crusher will do the job.

Cone crushers: The popular choice for getting excellent cubicle product

The cone crusher is renowned for providing a very high content of cubic material in the finished product.

It is ideal for crushing mid-hard and above mid-hard ores and rocks into much smaller pieces.

Cone crushers are typically applied in secondary and tertiary crushing stages. Therefore, if you need your finished products to be much smaller in size and perfect in shape, use the cone crusher.

Cone crusher VS Jaw crusher: Key differences

Cone crushers and jaw crushers both perform well in quarries, aggregates plants, sand making plants, cement plants, etc. However, many still do not know which one to choose.

To help you decide, now let's dive into the differences between cone crushers and jaw crushers.

1. Different production characteristics

Feeding size: The jaw crusher has a relatively large feed size range, and can generally handle materials below 1, 200mm, while the cone crusher is relatively small, generally requiring less than 450mm (depending on the specific conditions of the product).

Discharging size: The Jaw crusher is normally used for primary crushing which will give you a big crushing capacity and the output size is bigger but suitable for secondary crushing. While cone crusher is for secondary and tertiary crushing stages, thus having a smaller discharging size.

Capacity: In terms of processing capacity, the output of the cone crusher can generally reach 2181t/h, which is more than double that of the jaw crusher.

Production characteristics Cone crusher Jaw crusher Feeding size ≤ 450mm ≤1, 200mm Discharging size 4-41mm 10-350mm Capacity ≤2, 181t/h ≤

1, 000t/h

2. Prices for cone crushers and jaw crushers

Affected by wearing parts and structure, the price of a cone crusher is much more expensive than that of a jaw crusher.

3. The overall structure of the machine

From the perspective of the overall structure, the cone crusher is 1.7-2 times heavier and 2-3 times higher than the jaw crusher with the same feeding opening size. A Larger machine means higher site costs.

4. Material handling

The jaw crusher is suitable for a variety of materials with different hardness, such as talc, limestone, chalcocite, hematite, pebble, granite, etc.

While the cone crusher is more suitable for hard rocks and ores, such as iron ore, granite, pebble. Besides, a cone crusher is not suitable for crushing viscous materials that contain a lot of moisture.

5. Feeding requirements

With a cone crusher, the material can be fed directly into the machine until it's full and no silos and feeders are needed.

With a jaw crusher, the material must be evenly fed into the crusher by a feeder, and the amount of material inside the crusher cannot exceed 2/3rd of the crushing chamber height. Extra feeders and silos mean more investment in auxiliary equipment.

6. The shape of the finished product

Compared with the jaw crusher, the cone crusher generally has a high content of cubic material in the product.

Therefore, in situations where cubic particles are needed, for example, the anti-skid pavement of high-grade highway, the cone crusher can be used as the crushing equipment to produce concrete aggregates.

7. Maintenance cost

Any equipment requires regular maintenance while in use. Although the cone crusher is more expensive than the jaw crusher, the later maintenance cost is low thanks to the longer maintenance cycle prolonged by the wear-resistant parts and simple maintenance.

Conclusion

When choosing a stone crusher, knowing the seven differences between a cone crusher and a jaw crusher can help us make the right decision. But that is not enough. You also should know the following facts when choosing between cone crushers and jaw crushers.

Comparative Analysis: Jaw Crusher vs. Impact Crusher vs. Cone Crusher

2023-11-30 | Author: SBM

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.

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.
