The roller milling, or high grinding method slowly replaced most existing traditional stone mills. With roller milling, steel rollers quickly explode the grain over a series of passes through the mill. The reground flour is thoroughly sifted to remove the bran and germ, thereby also removing some of the nutrients.

Milling Methods for Mid-Gauge to Ultra-Fine Particle Size Ranges Roller Mills In a roller mill, material moves between pairs of counter-rotating cylinders, which exert crushing and shearing forces. The gap between rolls is adjusted according to raw feed size and goal particle size range.
Stone-milling means all the grains are ground in one process, all their goodness is retained, and the whole stoneground grain imparts a lovely nutty flavour to the flour, with great texture. Roller Milling As populations grew and the demand for more and better flour and bread grew, so a new milling process was devised.
Mar 01, 2020 1. Introduction. Grain milling might be the oldest manufacturing process in the world.

A healthy grinding. The heart of the stone mill is the millstone. The size of the millstone is not decisive for the fineness of the flour. On the contrary, the optimal adaptation of the grinder diameter and the speed, is of great importance, controlled by a three-phase motor. The combination of the rotation speed with the distance between the stones ensures a perfect
Mar 31, 2020 Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.
