The difference between impact crusher and jaw crusher

Impact crusher and jaw crusher are both commonly used in the field of ore crushing. However, there are some differences between the two in terms of their working principle, application, and output size.

Working Principle: The working principle of jaw crusher is that the material is subjected to comprehensive force between the movable jaw plate and the fixed jaw plate, and the material is crushed by squeezing, rubbing, and grinding repeatedly. The working principle of impact crusher is that the material is subjected to the impact and crushing of the high-speed rotating rotor, and the impacted material is accelerated and crushed by the mutual impact of the hammer and the counter-cavity lining plate.

Application: Jaw crusher is mainly used for the primary crushing of large pieces of materials, with the coarse crushing performance of large crushing ratio and uniform particle size. The materials crushed by jaw crusher are widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. Impact crusher is mainly used in the fields of metallurgy, chemical industry, building materials, hydropower and other fields that need to process materials that have high hardness and brittle properties, such as limestone, coal, calcium carbide, quartz, dolomite, iron ore, etc.

Output Size: The output size of jaw crusher is generally between 10-350mm, while the output size of impact crusher is between 0-50mm. The finished product of jaw crusher has a good shape, with uniform particle size and good quality, while the finished product of impact crusher has a slightly better grain shape, but its particle size is smaller, which may not meet the requirements for some application.

In summary, both jaw crusher and impact crusher have unique features and advantages, and the choice between the two crushers depends on the specific requirements of the operation and the properties of the processed material.

Sure, here are some differences between impact crusher and jaw crusher:

1. Working principle: Both impact crusher and jaw crusher work on the principle of crushing the material by applying pressure to it. However, the working principle of jaw crusher is oscillating motion whereas the impact crusher involves impact force.
2. Processing capacity: The processing capacity of an impact crusher is generally higher than that of a jaw crusher.
3. Maintenance: Maintenance for jaw crusher is simpler than for impact crusher. However, impact crusher requires frequent inspections and maintenance.
4. Feeding size: The maximum feeding size for jaw crusher is generally smaller than the feeding size of impact crusher.
5. Output size: The size of the output material from jaw crusher is generally less than that from impact crusher.
6. Cost: The initial investment cost of jaw crusher is generally lower than that of impact crusher.
7. Application: Jaw crusher is commonly used for coarse crushing, while impact crusher is suitable for medium or fine crushing of materials.

These are some of the key differences between impact crusher and jaw crusher.

Sure, here's a table outlining some key differences between impact crushers and jaw crushers:

Please note that this table is not exhaustive, and there may be additional factors to consider when choosing between an impact crusher and jaw crusher for a specific application.
