Dry milling of grain is mainly utilized to manufacture feedstock into consumer and industrial based products. This process is widely associated with the development of new bio-based associated by-products. The milling process separates the grain into four distinct physical components: the germ, flour, fine grits, and coarse grits.The separated materials are then reduced into food products ...

Get More· Should shops always defer to Swiss-type lathes to process small, long and often complex parts? Not necessarily. As a general rule, a Swiss-type is most appropriate for machining workpieces with L:D ratios of 4 to 1 or greater. Parts with lower L:D ratios may be machined economically on turn-mills.
