jaw crusher capacity taggert formula

The Taggart formula is a widely recognized method for estimating the capacity of a jaw crusher. Developed by Fred Chester Bond and further refined by Arthur Taggart, this formula provides a practical approach to determining the theoretical throughput of a jaw crusher based on its operational parameters. The formula is particularly useful for engineers and designers who need to estimate crusher performance during the planning stages of a project.

The Taggart formula is expressed as: Capacity (in tons per hour) = (0.6 * W * S * s * d * n) / 1000, where W represents the width of the crusher feed opening in inches, S is the open-side setting of the crusher in inches, s is the closed-side setting in inches, d is the density of the material being crushed in pounds per cubic foot, and n is the speed of the crusher in revolutions per minute. This equation accounts for key variables that influence crusher performance, such as feed size, discharge size, and machine speed.

While the Taggart formula provides a useful estimate, it's important to note that actual crusher capacity can vary due to factors like material characteristics, moisture content, and feed gradation. Harder materials or those with high clay content may reduce throughput significantly. Additionally, improper feeding conditions or unevenly distributed material can further impact performance. Engineers often use this formula as a starting point and adjust their calculations based on empirical data or manufacturer recommendations.

The formula's simplicity makes it appealing for preliminary assessments, but modern crushing operations often rely on more advanced methods for precise capacity calculations. Computer simulations and proprietary software tools now complement traditional formulas like Taggart's. However, understanding these fundamental relationships remains valuable for troubleshooting and optimizing jaw crusher operations in various industrial applications.
