assures the reader that one can make good Black Powder using different kinds of ball mills, or perhaps even without a ball mill. Along the way this book dispels myths, kills sacred cows, and takes some rather irreverent swipes at the self-appointed amateur Black Powder theocracy. For all these sins its author is unrepentant and unapologetic.
transferred into the ball mill. The diameter of balls in the mill was 9.1 mm, and the mixer speed 50 rpm. The ball mill was equipped with a recirculation system, with a speed of 10 kg/h. The internal diameter of the ball mill was 0.250 m, and the height 0.31 m. The volume of the space provided for balls and 5 kg of chocolate mass was 0.0152 m3.

After removing ball mill and by changing "b4" and "n4" in the new model, some parameters such as d80 of ball mill No. 2 product, percentage of -38 microns particles and circulation load percent were calculated and are shown in Table 4. All the results were analyzed and the best on-line control path was determined for engineers and operators.
Ball mill is a high-energy mill process especially used for an energy-intensive process like mechanical alloying, mechanochemistry, or mechanical activation. Planetary ball mill is used to determine the dependence of process efficiency using milling parameters such as ball size and number, mill geometry, and velocity of the rotating parts.
