How to choose the proper secondary crusher between cone crusher and Impact crusher?

Choosing between a cone crusher and an impact crusher as a secondary crusher depends on several factors related to your specific needs, operating conditions, and the characteristics of the material you’re processing. Here are some key considerations to help you make an informed decision:

 

Material Hardness and Abrasiveness

 

Consider the hardness and abrasiveness of the material you’re crushing. Cone crushers are generally better suited for hard and abrasive materials, while impact crushers may be more effective for softer materials.

 

Particle Size Requirements

 

Determine the desired particle size distribution of the final product. Cone crushers tend to produce more cubical-shaped particles and are typically used for secondary and tertiary crushing stages where precise particle shape is important. Impact crushers, on the other hand, may produce more angular and elongated particles.

 

Production Capacity

 

Evaluate the required production capacity and throughput of your operation. Cone crushers are often chosen for higher capacity applications due to their ability to handle larger feed sizes and higher tonnages compared to most impact crushers.

 

Maintenance and Operating Costs

 

Consider the maintenance and operating costs associated with each type of crusher. Cone crushers generally have higher initial costs but lower maintenance costs over the long term compared to impact crushers. Impact crushers may require more frequent maintenance and have higher wear and operating costs due to the use of impact bars and blow bars.

 

Environmental Considerations

 

Evaluate the environmental impact of each type of crusher, including factors such as noise levels, dust generation, and energy consumption. Impact crushers may produce more dust and noise compared to cone crushers, which could be a consideration depending on your operating environment and regulatory requirements.

 

Feed Size and Feed Gradation

 

Assess the size and gradation of the material you’ll be feeding into the crusher. Cone crushers are typically used for finer crushing applications where the feed material is relatively uniform in size and gradation. Impact crushers can handle a wider range of feed sizes and may be more suitable for applications with variable feed characteristics.

Application Specific Requirements

 

Consider any specific requirements or preferences related to your application, such as portability, mobility, and ease of maintenance. Impact crushers are generally more compact and portable compared to cone crushers, making them a preferred choice for mobile or portable crushing plants.

 

Ultimately, the best choice between a cone crusher and an impact crusher as a secondary crusher depends on a thorough understanding of your specific requirements and operating conditions. It’s recommended to consult with a reputable equipment manufacturer or a crushing equipment expert to help you evaluate your options and make an informed decision.
