Surface Grinder Coolant Filtration
In the case of large filter rollers it's a sheet of filter material supported by a chain conveyor right over the coolant tank. You can stretch the life of filter socks by nesting them, IE put a 20 µm sock inside a 5 µm sock. The 20 µm catches most things, and the 5 µm only catches 5 to 20 µm particles.

The coolant viscosity should be low enough so the fluid easily floods the grinding zone. Coolant surface tension should be low so grinding swarf can settle and filter out. Before roll grinding begins, any personnel involved in the operation must read the coolant's safety data sheet (SDS) so they understand how to safely handle the fluid.
