ABSTRACT:
A roller mill system (10) for grains such as wheat provides a frame structure (12), power apparatus (14), and first, second and third roller structures (16,18,20) collectively presenting an inverted pyramidal configuration. In this fashion three rollers (76,90,102) provide two nips or passages (122,124), thus eliminating the need for a fourth roller as in conventional two-passsage mills. Grain or the like is fed from grain hopper (38) into passage (122) where it undergoes processing action such as mashing or crimping. The grain is then transported to passage (124) for a second processing action. The processed grain, which is now reduced in particle size, is conveyed to a collection site (146) for further processing or packaging. Due to the relative angular velocities of rollers (76,90,102), all grain is transported to second passage (124) and virtually none escapes through passage (126). This is true despite the lack of any feeding mechanism to introduce the processed grain from (122) to passage (124). In the preferred embodiment the respective relative angular velocities for the first roller (76), second roller (90) and third roller (102) are 198 rpm counterclockwise, 135 rpm clockwise and 230 rpm counterclockwise.
