Structure Supporting Jaw Crusher
Structure Supporting Jaw Crusher
(OP)
I have a new Jaw Crusher and its Grizzler installed in our plant. In trying to run the jaw crusher and the grizzler feeding the jaw crusher I am having a very big problem of vibrations on structures which are very abnormal. I suspect structureal issues supporting the grizzler and the jaw crusher to be the problem associated with these vibrations. Can anyone assist in the the way in which structural issues can cause severe vibration problems when supporting crushers.

Are you talking about a structure that is already erected that is experiencing vibration problems? Or are you designing the structure and having problems with vibrations in your model?

Now I know why!

You may want to get with the structural engineer and ask him what (if anything) he did to account for the unbalanced loads.
There are a few companys that handle this that I can recommend if you want.

If this is the new process you will need to check above. If this happens on the existing and long time working plant, you need to check the structure against the drawings for the missing members or failed connections. Additionally I would suggest you to check the crusher connections onto the structure.

I'll say this for zetmech's benefit: Be careful with this. I've run into a number of situations where this was not adequate. (Several in fact where issues had to be addressed after construction.) It is a good starting point for design......BUT.....it doesn't guarantee the performance you want.
If the guy who did your design addressed the situation only by doing that (in lieu of a dynamic analysis)......that may be where it went wrong.
