Types of Impact Crusher In Different industry

Impact crushers are specialized machines used in various industries such as mining, construction, and recycling to break down materials into smaller pieces. These machines are specifically designed to crush hard rocks and ores and are available in different types, each catering to specific applications. In this article, we will discuss the various types of impact crushers and their respective applications.


Impact crushers have become a popular choice for crushing rocks and ores due to their versatility. They can performing a wide range of tasks and can be utilized in different industries, including mining, construction, and recycling. However, not all impact crushers are the same, as each type has its unique features and advantages. Understanding the differences between these types of impact crushers is crucial in selecting the right machine for your specific requirements.

What is an Impact Crusher?

Impact crushers operate by using striking rather than pressure to reduce the size of materials. These machines have a cavity with openings on the bottom, side, and top, into which the material is fed. Once inside the cavity, the material is struck by the blow bars, breaking it down into smaller pieces for further processing. There are different types of impact crushers available.Each type is designed for specific applications. Below, we will discuss the most common types of impact crushers.

Horizontal Shaft Impact Crusher (HSI)

A HSI crusher is a type of impact crusher that use a horizontal shaft to crush materials. The shaft is placed horizontally and fitted with wear-resistant hammers. As the material enters the machine, the hammers strike and break it down into smaller pieces. HSI crushers are commonly used in aggregate and mining applications.

Vertical Shaft Impact Crusher (VSI)

A VSI crusher is another type of impact crusher adopt a high-speed rotor to throw material against a hard surface, such as a rock. The material is fed into the rotor, which is fitted with wear-resistant tips and thrown out at high speed. VSI crushers are often applied in the production of sand and other fine materials.

Primary Impact Crusher

A primary impact crusher is designed to handle large pieces of material, such as rock or concrete.  They are used in applications where a high reduction ratio is required, such as in the construction and mining industries.

Secondary Impact Crusher

A secondary impact crusher is used after a primary crusher and is designed to process smaller pieces of material, such as gravel and sand. These crushers are commonly used in the construction and demolition industries.

Tertiary Impact Crusher

A tertiary impact crusher is used in the final stage of crushing to produce a high-quality, uniform cubical shape of material. These crushers are often used in the production of aggregates for concrete and asphalt.

Advantages of Impact Crushers

Impact crushers has several advantages over other crushing machines, including:

  • High reduction ratios

Impact crushers can achieve very high reduction ratios,which making them ideal for crushing hard materials.

  • Versatility

Impact crushers can be used for a variety of applications, such as crushing hard rock and recycling materials.

  • Low operating costs

Impact crushers are generally less expensive to operate than other types of crushers.

  • Easy maintenance

Disadvantages of Impact Crushers

Despite their advantages, there are also some disadvantages to using impact crushers. These include:

  • High wear and tear

Impact crushers are subject to high wear and tear due to the forceful impact of the blow bars on the material being crushed.

  • Limited size reduction

Impact crushers are not suitable for reducing the size of materials that are very hard or have a high moisture content.

  • Dust generation

Impact crushers can generate a lot of dust, which can be a concern for the environment and the health of workers.

Choosing the Right Impact Crusher for Your Needs

There are several factors to consider when choosing an impact crusher:


The type of material you need to crush is the primary consideration when choosing a impact crusher.


The capacity of the impact crusher should be suitable for the amount of material you need to process.


The size of the impact crusher should be able to reduce the the material to required size.


The power of the crusher should be sufficient to handle the material being crushed.


You should also take the ease of maintenance and the availability of spare parts into consideration.

Maintenance and Service

Impact crushers needs regular maintenance to ensure they are working at optimal efficiency. This includes:

  • Checking and replacing wear parts, such as blow bars, as needed
  • Regularly lubricating bearings and other moving parts
  • Keeping the crusher clean and free of debris
  • Performing regular inspections and maintenance to identify and address potential issues

Safety Considerations

Safety should always be a top priority when operating impact crushers. Some important safety considerations include:

  • Ensuring that all workers are properly trained and familiar with the equipment
  • Providing appropriate personal protective equipment, such as hard hats and safety glasses
  • Ensuring that the crusher is properly guarded and that access to the machine is restricted when it is in operation
  • Following all safety guidelines and regulations, such as those set forth by OSHA

Environmental Impact

Impact crushers can have a significant impact on the environment, particularly if they are not properly maintained and operated. Some potential environmental impacts include:

  • Dust generation
  • Noise pollution
  • Water pollution, if the crusher is located near a body of water
  • Soil erosion, if the crusher is located on or near a slope or hillside

To minimize the environmental impact of impact crushers, it is important to properly maintain and operate the equipment, as well as to follow all applicable environmental regulations.


Impact crushers are versatile machines that are commonly used in a variety of applications, from mining to construction to recycling. By understanding the different types of impact crushers available and their applications, you can choose the right machine for your needs. It is also important to properly maintain and operate the equipment to ensure optimal performance and to minimize any potential environmental impacts.
