Re: Fogless cooling mixer specs request
I did mine a bit different, in that I use a pressure tank fo feed the coolant. Can control the air and fluid independently. Constant fluid flow at any air flow. Puts out micro droplets, no fog.
Flow controls on both air and fluid lines, 1/4 inch air, and coolant feed lines.
1/8 tubing is normal nylon water line, available from any hardware store.
The 1/8 line goes right through the Tee and down the center of nozzle tube
I sized the 1/8 tube to stick out the end of the nozzle 1/8 inch or so
Harbor Freight 20 lb sandblaster pressure tank, about 4 gal. coolant capacity.
Normally pressurized to about 30 PSI.
and on my dirty mill.
At about 5% flow, about 1/2 cup / hr
At about 40% flow, almost never run it this high, 5% is more normal
