2013-4-7assures 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

The bond grindability index and work index of ball mill were determined for different feed characteristics by varying the number of balls involved in grinding operation in the ball mill. The higher specific rate of breakage was obtained for new or smooth surfaced balls than old or rough surfaced balls

2020-5-26I Have been been wondering about the correlation between Protein content in flour and their useability for baking. Through some web searchI learned that Protein content of a flour gives nothing more than a hint as to the strength of the flour. I read that some amino acids that make up protein are usually soluble and contribute little to the strength of a flour.In search of
