machine foundations on vibrating floor
(OP)
Hello,
We are going to install 4 plastic film extruders and 3 sealers over a floor which vibrates. The warehouse next to ours produces calcium carbonate with mills with no proper vibration absorbers. I am sure this situation will end up causing problems in our machines.
All the information I have found on foundations is to insulate the ground from machine vibrations and not the opposite.
Can anyone tell me what kind of foundations shall I use? Wich are the special cares I shall look for?
Thanks a lot folks!

Is it that bad? there is no way to get the problem solved?

Isolated foundations and inertia masses are typically free-floating concrete and/or steel masses that are supported by vibration and shock isolators. Isolated foundations are typically used to protect precision machinery or equipment from incoming vibration and shock. Whereas, inertia masses are typically used to add mass to a machine to control motion and to improve isolation of transmitted forces to surrounding areas.

Obviously, you have to isolate the frame and machinery (that which you want steady) from the vibration.
Then you can either use a massive poured foundation and extra-heavy mass under each machine on those foundations to slow the movement and change the natural frequency. Note; You might want to allow higher frequencies, or allow lower frequencies to be present.
but testing and trials are expensive to setup and run.
Or you can create a single larger super-rigid frame for the machinery (to keep everything in alignment and at the right distances and tension with respect to the "row" of production machinery processes). Source, heater, extrusion feeder, extruder, cooler, wrapper for example probably cannot be allowed to movement or vibrate against each other, but the whole row can move slowly as a single assembly on a single frame.
