For turning use 90-120 SFPM .005-.007 IPR. If you are considering ceramic expect a lot of movement if the piece is not solid because you do not use coolant when milling with ceramic and workpiece must be very rigid. If you want to be safe go with carbide. Inconel 625 is a lot softer than 718 it can almost be treated as stainless.


Turn on your Ball Mill and let it rotate for 2 to 4 hours. As the Ball Mill rotates, the lead balls will crush the chemicals together and reduce them into a super fine powder. The longer you let it grind, the stronger your Black Powder will be. Let the Ball Mill do its grinding in an uninhabited area, not in a place like your bedroom.

How is Ethanol Made?

Dry Mill Ethanol Process. In dry milling, the entire grain kernel is first ground into "meal," then slurried with water to form a "mash.". Enzymes are added to the mash to convert starch to sugar. The mash is cooked, then cooled and transferred to fermenters. Yeast is added and the conversion of sugar to alcohol begins.


The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 40-10 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and ...
