bounding and grounding
(OP)
I recently got a new job in a plant that do repackaging and plastic grinding. Everything here is pretty old, and almost nothing nothing is grounded! An other problem I have with this is that the building is made of wood, so I cannot ground the machines to the structure.
Now, I need to resolve this but I never done that before. Shouldn’t be too complicated, but I was wondering if you guys have any tips regarding this.
The equipments being used: pneumatic conveyor, discs mill, plastic bin, sifter...

Another recommendation is that you contact a firm specializing in grounding system design. Grounding is a scientific process and one on which equipment protection and human safety are critically reliant. Define exactly what grounding installations and improvements will work best for your site. This eliminates trial and error, and reduces the overall cost of the grounding system by designing only what is needed to meet your specifications.
The most common is Single Vertical Rod Design. I have installed many of these systems using a grid approach, attaching the equipment to the grid with CLAD welds.
The earth-ground resistance for a single electrode, such as a driven rod or electrolytic rod, can be calculated from the following formula:
R = r/2 p(l(2l/r)(1 + 2K))
Where
R = Resistance (ohms)
r = Mean soil resistivity (ohm-cm)
l = Length of rod (cm)
r = Radius of rod (cm)
K = Coefficient

Well first, does the equipment ground thru the third prong on the plug and if so, is the receptacle on the wall grounded? If both are true then your machines are grounded
Just a quick observation…
Good luck
