What is the difference between impact crusher and hammer crusher(hammer mill)?

hammer crusher (hammer mill)

When it comes to crushing equipment, there are many options to choose from. Two of the most commonly used crushing machines are the impact crusher and the hammer mill. These machines have different working principles and features that make them suitable for various crushing applications. In this article, we will explore the differences between an impact crusher and a hammer mill.

The primary difference between these two crushing machines lies in their way of breaking materials. Impact crushers use the impact force to crush the materials. The rotor rotates at a high speed under the driving force of the motor, and the materials are impacted by the hammers on the rotor. Hammer mills, on the other hand, use the force of repeated impacts and attrition between the hammers and the materials to crush them.

Another difference lies in the crushing capacity. Impact crushers are capable of producing a higher amount of fines compared to hammer crusher. This is due to the high-speed impact forces that occur in the crusher, resulting in a higher reduction ratio and a more uniform shape of the finished product. Hammer mills, on the other hand, are known for their ability to produce a wide range of particle sizes. These machines can be used for both coarse and fine crushing, depending on the size of the screen openings in the mill.

In terms of versatility, both impact crushers and hammer mills can be used in a variety of applications. However, impact crushers are often used in the aggregate and mining industries for primary and secondary crushing operations. They are ideal for processing materials with high abrasiveness and are capable of producing excellent cubicity and shape of the final product. Hammer mills, on the other hand, are commonly used for crushing softer, non-abrasive materials such as limestone, gypsum, coal, and others.

In conclusion, the main differences between an impact crusher and a hammer mill lie in their way of breaking materials and their versatility. Impact crushers use the impact force while hammer mills use attrition and impact forces. Both machines are suitable for crushing different types of materials, but they excel in different applications. Understanding these differences will help you choose the right crushing equipment for your specific needs.
