Comparison of Impact Crusher and Hammer Crusher

Comparison of Impact Crusher and Hammer Crusher

Impact crushers and hammer crushers are both used to crush materials, but there are some differences between them. Here is a comparison between the two types of crushers:

1. Different crushing principles:

The impact crusher and the hammer crusher both crush materials by impacting them with a hammer-like structure. However, the crushing principles are different. The impact crusher uses the principle of impact crushing, while the hammer crusher uses the principle of hammer crushing.

2. Different applications:

The impact crusher is mainly used for medium-hardness and lower-abrasive materials, such as limestone, coal, calcium carbide, quartz, dolomite, iron pyrites, gypsum, and chemical raw materials. The hammer crusher is mainly used for crushing medium-hardness and brittle materials such as limestone, coal, salt, chalk, gypsum, brick, and tile.

3. Different discharge particle size:

The impact crusher can produce a more uniform particle size distribution with a higher productivity. The hammer crusher produces a coarser, less uniform particle size distribution with a lower productivity.

4. Different structure:

The impact crusher has a larger crushing chamber, a higher feed inlet, and a rotor with a larger diameters and shorter length than the hammer crusher. The hammer crusher has a narrower outlet and uses a straight, cylindrical rotor.

5. Different wear parts:

The impact crusher has a high chromium plate hammer and special impact liner plate. The hammer crusher's hammerhead is made of high chromium cast iron with good abrasion resistance.

Here is a summary table of the comparison between impact crushers and hammer crushers:

Overall, both impact crushers and hammer crushers have their respective advantages and disadvantages. Choosing the right type of crusher depends on the material to be crushed, the required particle size, and the production capacity. By comparing the characteristics of the two crushing machines, users can make a better choice for their specific needs.
