The 30 degrees that did the trick. In the 1920s, the challenge for industrial grinding was to combine the high capacity of pendulum mills with the smooth operation of Maxecon mills. The breakthrough came with a subtle angle variation. By adjusting the roll axis from 45 to 30 degrees and tilting the mill wall backward, engineers made it possible to use larger diameter rolls on the same grinding track. This led to the first Loesche mill, which was patented in 1927. It featured a rotating grinding track that used centrifugal force to push material outward. By 1928, two 12-ton mills using this technology were successfully in operation. This 30-degree adjustment is an example of precision engineering; a smart modification that led to the advances in industrial grinding that we know today. It shows how even a small change can have a profound effect on future possibilities. #flashbackfriday #verticalrollermill #industrialengineering #history
