Roller mill - Wikipedia
Four-roller mills Four-roller mills have two sets of rollers. When using a four-roller mill to mill grain, the stone first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits. stone is sieved out of the cracked grain, and then the coarse grist and husks are sent through the second set of rollers, which ...
Milling (machining) - Wikipedia
In the vertical mill the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. The spindle can generally be extended (or the table can be raised/lowered, giving the same effect), allowing plunge cuts and drilling. There are two subcategories of vertical mills: the bed mill and the turret mill. A turret mill has a stationary spindle and the table ...
