The Mechanics of Metalworking Fluids
Remove Particulates
Finally, both floating and sinking chips should be removed so they do not
interact with the chemical components of the fluid to cause premature failure.
Although most of the material sinks the bottom, even if a conveyor is in
operation, they will interact with any fluids that they touch.
A shovel or industrial vacuum may be used to remove the larger, sinking chips. A
general filtration system should be used regularly to remove all others. Some
floating chips may be filtered via a coalescing unit with this capability, however,
very fine chips, such as 5-25µ in size, should be removed after the oil has
separated, or re-emulsion can occur.
