Impact crusher VS hammer crusher

Both impact crusher and hammer crusher are suitable for crushing medium hard and soft materials, but the impact crusher is mostly used as the secondary crushing equipment. While the hammer crusher is mostly used in the cement production line, as the limestone raw material crushing equipment, or as the primary crushing equipment in the sand aggregate plant.

As a widely used crushing equipment, impact crusher and hammer crusher are often compared. Those are simple to operate and the price is favorable.They also have certain differences in actual production.

1. Crushing Chamber

The crushing cavity of the impact crusher is large, so that the material has a certain moving space, and the impact effect is fully utilized. In comparison, the crushing cavity crusher by hammer is small, the impact cannot be fully exerted.

2. Crushing ratio and finished product type

The crushing ratio of impact crusher can reach more than 50, and the particle shape of the finished material is good. The output particle size is uniform, and the content of fine powder and dust is low.The crushing ratio of the hammer crusher is generally 10-25, the highest can reach 50, and the powder content is relatively high.

3. Different purpose

Impact crusher is used as second stage crushing machine to make aggregates. The final crusher stone size is 10-40mm for road, railway, highway etc. Hammer crusher is a traditional sand making machine. The powder size is less than 10mm. Due to small size and low cost, it is used to crush kinds of material, such as limestone, glass, shell, gold ore etc.

Hammer crusher and impact crusher have their own advantages, you can choose the right machine according to your needs.

People Also Frequently Asked Question-FAQ:

1. Is a hammer mill an impact crusher?

A hammermill is one of several types of crushing machines, including impact crushers, jaw crushers, and cone crushers, that is manufactured for the purpose of processing raw materials to reduce them in size. It is different from impact crusher due to the hammer sturcture.

2. What is a impact crusher?

An impact crusher is a machine that uses striking as opposed to pressure to reduce the size of a material. Impact crushers are designated as a primary, secondary, tertiary or quarternary rotor crusher depending on which processing stage the equipment is being utilized.

3. What are the different types of impact crushers?

Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers.

4. How do I choose a crusher?

Important specifications and features when selecting industrial crushers include:
Feed size, material, and hardness must be considered.
Output size ranges.
Crushers accept dry or wet input, or both.
Crushers are feed in batches or continuously.
Capacity requirement
