Explains how the Close Side Settings of Crushers controls the product size and ultimately the complete reduction ratio.
Crusher Vision is an automated closed side setting system for gyratory crushers that measures the gap between the concave and mantle. Toll Free USA +1 (866) 419-1619 Worldwide +1 (715) 214-2162
This patent pending system and method is for measuring the closed side setting (CSS) on gyratory crushers. This measurement method is used to provide more accurate data and faster data collection times than current methods used today. The benefit of using the system is the fact that data can be obtained within minutes.

A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.
The A-zone beneath the screen is communicated through the hollow ribs and openings in the body side walls with the B-zone around the shaft close to the inside surface of body side walls. As a result, the circulation of suspended matter in the gas between A and B zones is established and the high pressure of air in the discharging unit of crusher is reduced.
28/4/2017 “Fines in the crusher feed” is defined as material entering the top of the crusher, which is already equal to or smaller than the crusher’s closed-side discharge setting. As a rule of thumb, the maximum number of fines in the crusher feed should not exceed 25 percent for secondary crushers or 10 percent for tertiary crushers.
