An experimental durum wheat semolina mill flow was developed for the GRL Ross experimental mill to study the effects of changing roll flute orientation from dull to dull to sharp to sharp. Changing roll flute orientation did not influence the relative quality rankings of durum wheats, but mill stock distribution, semolina quality, spaghetti ...

The corrugations of roll R4 are of Twin City Chunk style as illustrated in FIG. 3 of the drawings and are preferably oriented in "dull to dull" relationship. The product outflow from reduction rolls R4 is directed immediately into the nip between smooth surfaced finishing rolls R5, each of which is preferably about 9 to 10 inches in diameter.

Bought this mill after a long wait. My old way of hand-cranking grains using a 15yr old single roller PhilMill got pretty old once I started making 10 and 15.5 gallon batches, including grain bill heavy big Belgian beers. After looking at the usual roller mills, plus dedicated motor, this Maltzilla was very competitively priced.

LOST TEETH (LT) – Roller Cone Bit Dull Characteristics. On this bit, the middle row of the Number One cone is a good example of cone cracking running in a circumferential manner from the bottom of the insert hole to the bottom of the adjacent insert hole. This has loosened the hold of the cone on the insert, resulting in the loss of some inserts.
