Eccentricity of Jaw Crusher Shaft - follow up
Posted by Dambula from Choma, OT, ZM on June 23, 2007
Kindly refer to the question which I asked previously and thank you for your response. I think I reversed the crusher dimensions and mentioned 12″x7″ instead of 7″x12″. In view of this change, would the recommended 1″ eccentricity still apply to a 7″x12″ crusher.
Leave the eccentric at the 1.000-inch mark for a starting point, but you’ll want to try various lengths and positions of toggling points. That’s how you’ll achieve the action of the machine.
For example, if you want to close this machine down to a 1.000-inch discharge setting, you’ll want it to toggle in such a manner as to provide an open position setting of 2.000 inches. Most crushers of this feed opening and approximate width have jaws slightly over 24.000 inches long. Toggle the machine in such a manner that the discharge match points align somewhere between the open and closed side settings, perpendicular to the back of the moving jaw. If you’re building something from scratch, you’ll have a little trial and error in your preliminary modeling.
