A Detailed Explanation of the 7 Differences Between Cone Crusher and Jaw Crusher in Fine Crushing

In the stone crushing production line, the reasonable configuration of crushing equipment plays a crucial role in increasing production and improving the stone shape and particle size distribution. Currently, the entire crushing production line process includes three main stages: coarse crushing, medium and fine crushing, and screening. In the fine crushing stage, there are many crushers to choose from. What kind of equipment is more suitable?

The structure and principle of the fine jaw crusher are similar to those of the jaw crusher. The working mode is the flexural extrusion type. The materials are squeezed and crushed in the crushing chamber composed of a movable and fixed jaw. The cone crusher adopts laminated crushing. The mortar wall continuously moves toward the crushing wall to squeeze the materials sandwiched between the two and crush them.

The difference between the two in actual production:

1. Production characteristics

Generally speaking, fine jaw crusher and cone crusher have the following characteristics:

1) The feed particle size range of the fine jaw crusher is relatively large, and it can generally process materials below 1000mm, while the cone crusher is relatively strict, generally requiring less than 300mm (depending on the specific situation of the product);

2) In terms of processing capacity, the cone crusher far exceeds the fine jaw crusher, generally up to 1000 t/h, more than twice that of the fine jaw crusher;

3) In processing hard materials, the compressive strength of the two is the same, between 300-350Mpa.

2. Overall structure

From the overall structure, the cone crusher is 1.7-2 times heavier than the fine jaw crusher with the same feed size, and the body is generally 2-3 times higher than the fine jaw crusher, so with a relatively large construction cost of the plant.

3. Processing materials

The cone crusher is not applied for crushing wet and sticky ores, while the fine jaw crusher can process almost all kinds of materials.

4. Feeding requirements

The cone crusher can be filled with ore and directly fed without adding silo and feeders. However, the fine jaw crusher cannot be filled with ore and requires uniform ore feeding, so it is necessary to set up additional silos and feeders, which increases the investment cost of auxiliary equipment.

5. Finished product particle shape

The finished products of the cone crusher are more needle-shaped, and compared with the fine jaw crusher, the shaping effect of the cone crusher is slightly better in general.

6. Price comparison

The cone crusher price is much more expensive than that of the fine jaw crusher.

7. Use and maintenance

We know that no matter which kind of crushing equipment, it is inevitable to do regular inspections and maintenance. Despite the high initial investment cost of the cone crusher, a low failure rate in the later stage, the long replacement cycle of wearing parts, and the convenient maintenance and repair, which saves a lot of manpower and material investment.

We know that it is uncertain to choose which equipment to use for medium and fine crushing through the comparison of the above characteristics. We should consider it comprehensively when purchasing. Considering the equipment cost, when both equipment can meet the crushing needs and the required quantity is the same, we generally choose the fine jaw crusher; For large-scale factory production operations, it should apply the cone crusher; When crushing wet and sticky ores, it should apply the fine jaw crusher; When processing flake or long-strip hard ores, it should apply the cone crusher is suitable. The specific equipment selection still depends on the user's production requirements.
