Capacities are based on the following following assumed feed distributions: distributions: maximum feed to the crusher (F (F100 ) equals 80% of the feed opening size and 80% of the feed gradation (F 80 ) is equal to or less than 50% of the feed opening size. Bulk Density is assumed to be 1.6 metric tons per cubic meter. Capacities are calculated at the maximum eccentric throw for each machine size. Please note that the above capacities are typical, but crushing applications may vary widely with material, feed characteristics, moisture, moisture, and work index. FFE Minerals recommends recommends verification of throughput and ® capacities of Fuller-Traylor Gyratory Crushers Crushers for each installation. installation. Specific throughput needs can be met through engineering analysis and modification of crusher geometry.

Particle Size (mm)

To use the Product Analysis Chart, determine what particle size is required (X-Axis) and intersect the appropriate curve based on Open Side Setting (OSS). Correlate the intersecting intersecting point on the OSS curve to the Percent Passing (Y-Axis) to determine the approximate percent passing of an exact particle size at an exact Open Side Setting. EXAMPLE: For a Particle Particle Size of 150mm, what is the percent passing passing a 178mm OSS? OSS? The Percentage of 150mm particles passing an OSS of 178mm would be ~76%. Please note, these are typical product size distributions and vary widely with feed distribution and specific rock characteristics characteristics materials.
