How to find capacity of a cone crusher?

To determine the capacity of a cone crusher, you can follow these guidelines:

1. Understand the Formula: The capacity of a cone crusher is typically measured in tons per hour (TPH). A general formula for calculating the capacity is:

   $$Q=\frac{(CSS-OSS)\cdot RPM\cdot L\cdot E}{F}$$

   Where:

   • (Q) = capacity in TPH
   • (CSS) = closed side setting (the smallest distance between the two crushing faces)
   • (OSS) = open side setting (the maximum distance between the two crushing faces)
   • (RPM) = rotations per minute
   • (L) = length of the crushing surface (mantle)
   • (E) = efficiency factor
   • (F) = a factor to adjust for the fines and characteristics of the material being processed

2. Gather Essential Data:

   • Measure the "Closed Side Setting" (CSS) and "Open Side Setting" (OSS).
   • Determine the RPM of the crusher.
   • Get the length of the crushing surface.
   • Understand the material characteristics and efficiency.

3. Consult Manufacturer's Specifications: Manufacturers provide capacity charts or tables indicating the crusher's output based on different settings and material types. Using these charts simplifies the process.

4. Use Software Tools: Some manufacturers offer online tools or software calculators to help in estimating the capacity.

5. Consider Factors Affecting Capacity:

   • Feed size and distribution
   • Hardness and abrasiveness of the material
   • Moisture content
   • Desired product size and gradation

6. Perform Practical Tests: Conducting real-world performance tests with your specific material provides the most accurate capacity data.

7. Consult Experts: If there is any uncertainty, consulting with the manufacturer or a professional engineer is wise for accurate capacity estimation.

By following these steps, you can estimate the capacity of a cone crusher for your specific requirements.
