Impact crushers and hammer crushers are both commonly used equipment in the aggregate industry, and they are both capable of crushing a variety of materials. However, they are used in different applications and have some key differences.

An impact crusher uses a striking force to crush materials. It uses a spinning rotor with hammers or blow bars that strike the material, causing it to break apart. The material is then forced against a rigid surface, known as an anvil, which helps to further break it down. Impact crushers are typically used to crush soft to medium-hard materials such as limestone, gravel, and concrete. They are known for their high reduction ratios and ability to produce a cubical product shape.

A hammer crusher, on the other hand, uses a hammer to crush materials. The hammer is fixed on a rotor, which rotates at a high speed. The material is fed into the crusher and is hit by the hammer, causing it to break apart. Hammer crushers are typically used to crush harder materials such as coal, ores, and cement clinker. They are known for their ability to produce a fine product shape and high reduction ratios.

One of the main differences between impact crushers and hammer crushers is the type of crushing force they use. Impact crushers use impact, while hammer crushers use striking. This means that impact crushers are more suitable for softer materials, while hammer crushers are more suitable for harder materials.

Another difference is the way the crushers are designed. Impact crushers have a vertical shaft, while hammer crushers have a horizontal shaft. The vertical shaft design allows for better force distribution, which helps to produce a cubical product shape. The horizontal shaft design allows for better flow of material, which is useful for harder materials.

Impact crushers are also known for their low maintenance requirements. They have fewer moving parts and require less maintenance than hammer crushers. Hammer crushers, on the other hand, have more moving parts and require more maintenance.

A key consideration when choosing between an impact crusher and a hammer crusher is the final product size. Impact crushers are typically used to produce a cubical product shape, while hammer crushers are used to produce a more fine product shape.

In summary, impact crushers and hammer crushers are both commonly used equipment in the aggregate industry. They are used for different applications and have some key differences. Impact crushers use a striking force to crush materials, while hammer crushers use a hammer to crush materials. Impact crushers are more suitable for softer materials, while hammer crushers are more suitable for harder materials. Impact crushers have a vertical shaft and are known for their low maintenance requirements, while hammer crushers have a horizontal shaft and require more maintenance.
