The roller-process technology introduced by the Grimes brothers had a tremendous impact on the regional flour milling industry. The flour produced by the roller process was superior to the buhr stone process which translated to a higher price and also made possible the construction of larger, more efficient mills.

Because of the current demands on mills to process much lighter exit gauges from increased incoming hot strip thickness, much larger reductions are necessary on individual mill stands, such high reductions at a nominal width result in a larger area of contact with corresponding higher rolling force, friction and heat generation (see Fig 1

The fineness of less than 20 µm had not yet been achieved by pendulum mills or only in connection with products with a high solid density, so ball mills or even jet mills had to be applied (Fig. 1). Conventional pendulum roller milling (Fig. 2) is an efficient comminution principle but was to date limited regarding fineness.

Automatic Roller Mill. Automatic's electric roller mills use parallel, corrugated steel rolls to produce precise particle size—every time. Automatic's one-fast-roll principle gives more capacity at up to a third less horsepower than with hammer mills. It also provides a self-cleaning action that prevents clogging or packing.

roller mill operator can control the particle size by widen-ing or narrowing the roll gap. For most roller mills, the roll gap is automatically adjusted through a PLC that's pro-grammed to change the gap to match the specs for a new product or batch. This allows roll gap adjustments to be made in just seconds while the mill is operating ...

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
