Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than …

INTERESTING STORY OF GRINDING BALLS
What did the ball mills look like and what design? By chance we came across a video in which the author came up with a very bold and interesting theory about this topic. In short, according to the author, many of the cannons (especially large calibre – diameter of 100mm and above) are actually ball mills for grinding iron ore.

From Quern to Computer: The history of flour milling
The roller mill at the turn of the century is perhaps epitomised by Vernon & Sons' mill at Birkenhead, Liverpool which opened in 1899. Built on the latest Simon system, the mill had two separate milling plants, one with nine 60 inch and twenty-seven 40 inch rolls, the other with nine 60 inch and thirty-five 40 inch rolls.
