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

Okay, but how fast is the thing actually rotating, or its rpm (revolutions per minute)? Since machining centers don''t have gas pedals (nor gages that announce the current cutting speed), spindle rpm is the value we have to plug into the CNC program. To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R,,
