The key difference between a roller-grinder and a roller-mill is that a roller-grinder has the ability to run each roll in a set at a different speed. This differential between the speed of the rolls creates a grinding action that is desirable for many applications. ... Sample port. Triple Roller-Grinder.

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 ...

The basic function of the three roll mill is a differential speed between the three rolls. The difference between the second and the third rolls is two to four times higher than the difference between the first and the second rolls. The dispersion takes place in the second nip; the first nip regulates the feeding of the second "dispersing" nip.

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 ...

fast roll speed, and roll speed differential. The objectives of this study were to: (1) investigate the effects of physical properties of wheat kernels and the operational parameters of a first-break roller mill on the power and energy requirements for size reduction; and (2) develop prediction models for power and energy

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.

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.
