lour milling is an ancient yet complex craft. Our
food value chains rely as much today as they have
for millennia on the miller's ability to turn grain
into a product that is healthy, nutritious, attractive, and
safe for the consumer.
The grinding rollers are at the heart of the operation. Spinning at high speed, they must work in perfect
harmony, accurately separating the bran from the enGRVSHUP SDVVDJH DIWHU SDVVDJH SURGXFLQJ HYHU ¿QHU

If the cutting angle begins to wear, it will not cut
correctly and will inhibit the miller's ability to set the
rollers properly. The process will change from a cutting action to a crushing action. This not only requires
more energy, it also fails to deliver the right kind of
granular product.
