Breaking Down the Differences: Cone Crusher vs Jaw Crushers

Breaking Down the Differences: Cone Crusher vs Jaw Crushers

The primary crushing equipment is widely used in road construction, building, quarrying, mining, and recycling sectors. When selecting a crusher, it is essential to ascertain the desired product size, shape, and output rate. In this article, we break down the differences between cone and jaw crushers to help you make a more informed decision.

1. Basic Structure and Operating Principle:

Cone crusher: A cone crusher consists of a concave surface and a conical head, both of which are typically lined with manganese steel. The concave is suspended from the top and rotates around its vertical axis, while the conical head gyrates within the concave. Material is fed into the crusher from the top, and the crushed product exits at the bottom.

Jaw crusher: A jaw crusher is comprised of a fixed jaw and a moving jaw. The moving jaw pivots around a hinge and moves forward and backward against the fixed jaw, crushing material between them. As the material is crushed, it is discharged from the bottom of the crusher.

2. Size and Capacity:

Cone crusher: Cone crushers are generally used for secondary or tertiary crushing stages. Cone crushers have a larger inlet opening and a smaller discharge setting than jaw crushers, allowing for a higher degree of flexibility with product size. However, the horsepower requirements are significantly higher than that of a jaw crusher. This is due to the necessary increased crushing forces and eccentric throws.

Jaw crusher: Jaw crushers are primarily used for primary crushing purposes. They have a wider inlet opening and larger crushing area, which allows for a greater capacity. Jaw crushers are capable of producing a more cubical product compared to cone crushers. However, the performance of jaw crushers depends on the motion of the movable jaw, which can vary depending on the type of material being crushed.

3. Maintenance and Operating Costs:

Cone crusher: Cone crushers require regular maintenance to prevent damage to the moving parts. Lubes, filters, and even external cleaning are essential to ensure optimal performance. Cone crushers also require more fuel consumption, resulting in higher operating costs compared to jaw crushers.

Jaw crusher: Jaw crushers require less maintenance than cone crushers. Grease lubrication systems are commonly used for lubricating the bearings. Jaw crushers can be checked easily for wear and tear of the parts. New jaw liners can be installed as the jaw plates wear, reducing downtime and maintenance costs.

4. Applications:

Cone crusher: Cone crushers are suitable for crushing a variety of mid-hard and above mid-hard ores and rocks. They can be used for secondary, tertiary, or quaternary crushing in aggregates production, mining operations, and recycling applications.

Jaw crusher: Jaw crushers are ideal for various crushing operations and are widely used in the mining and construction industry. They are designed to crush the hardest materials efficiently and effectively. Jaw crushers are commonly used for primary crushing stages but can also be used for secondary crushing.

In conclusion, both cone crushers and jaw crushers have their own advantages and are suitable for different crushing applications. Cone crushers are preferred for their more flexible production capacity and well-shaped end products. Jaw crushers, on the other hand, offer greater capacity and less maintenance. Ultimately, the choice between the two should depend on the specific requirements of your project.
