Hello Everyone.
i am envolving in a new expansion project en Bolivia. There was a discussion about foundation of crusher equipments, traditionally We use a concrete foundations. But i worked in one plant with steel foundation and we had a big vibration problems. But my mechanical collegues saw METSO cathalog with all steel foundations, and therefore they insisted in steel foundation. By my opinion is more confitable concrete foundations. I need more opinions.

Properly designed, especially to account for the low frequency vibration from the rotating drum and charge, either will work.  Also if not properly designed both can fail. 

In my opinion the design of the concrete foundation is easier, and will be of lower capital cost.  Steel foundations can be built quicker (no curing time) which is the reason many like them.

So if you have the time (at least an extra month) concrete will work well and be lower cost.  If you are in a hurry (much most people seem to be these days) steel will work, but takes more care in design and will generally cost more.

Steel is cheaper than concrete and faster to erect, but comes with a longer lead time. Due to its lower fire resistance, insurance premiums for steel structures tend to be higher.
