A roller mill is a milling machine that gently and gradually reduces material to a smaller size. There are one or two pair of chilled cast iron rolls inside the machine. These rolls are lying parallel and are supported at each end by roller bearings. The back roll is in a fixed position and the front roll is movable to adjust the roll clearance ...

In a hammermill, the screen-hole diameter controls the maximum finished particle size of any ground product. When using roller mills, there is no screen being used, and unless the product is sifted and the coarse fraction reprocessed, the resultant particle size is purely reliant on the miller's skill in setting the roller mill effectively.

The full-feature roll-adjustment system provides a digital readout of the roll gap. A quadrature ring kit, mounted on the end of one jack screw, keeps track of the motion of the coupling shaft and converts this into gap distance. The digital readout displays the gap distance to an accuracy of +/-0.025 mm.

For roller mill grinding, roll gap was the most significant factor affecting energy requirement, followed by the roll speed differential. For hammer mill grinding, screen opening size had the most significant effect. For both mills, feed rate was not significant; and energy efficiencies were about the same.

All sam-ples were constructed to have a similar mean particle size (641 to 679 microns) with in-creasing PSSD (1.62 to 2.27). There was no interaction (P>0.10) between PSSD, added fat, and mill type. Increasing fat (P<0.04) and PSSD (P<0.001) decreased flow ability. These data suggest that the greater flow ability of roller mill ground corn ...
