All Metso C-Series Crusher models have a maximum possible setting as well as a minimum allowed setting, and Metso claims it is very important that the user understands why these are important to keep these in mind at all times.
The maximum possible setting is simply the maximum setting that the Crusher is physically able to accommodate. Typically, such setting is indicated with new jaw dies, and the setting actually depends on the jaw die profile as well as on whether a spacer is being used or not.
The minimum allowed setting (c.s.s. or o.s.s.) is the minimum setting at which the Crusher can be used when the Crusher is operated according to Metso’s recommendations. Metso warns the minimum allowed setting is very important as it takes into account the design and operation limits of the Crusher. Metso states not respecting these recommendations can lead to a poor utilization of the jaw dies (high scrap rate) as well as a shortened Crusher life.
I have a C106 to run. Is the Metso talk just fear mongering voodoo or real?
I want to crush as fine as I can. Metso is telling me to run as if I had hard rock or my warranty will be voided. Tell are not telling me what my Mpa actually is. (All I know is my BWi = 15).
What hardness test do I perform to confirm my rock's Mpa?
Thank you!
