Cereal processing | Britannica
Cereal processing and utilization Milling. Cereal processing is complex. The principal procedure is milling—that is, the grinding of the grain so that it can be easily cooked and rendered into an attractive foodstuff. Cereals usually are not eaten raw, but different kinds of milling (dry and wet) are employed, depending on the cereal itself and on the eating customs of the consumer.

Hammermills versus roller mills | World-grain
It should be stressed that the roller mill, when equipped with fluted or corrugated roll chills, can achieve a relatively fine grind, particularly when moisture content of cereals is optimized. The use of differential roll drive arrangements, which create a sheer effect between the chills, not only allows for a finer particle size output, but the sheering effect the roller mill has upon starch

SAG Mill Feed Chute Design| Long Life | Wear Resistant
This design of SAG mill feed chute lasted 9 months seeing 90,000 TPD. It is 600 brinell chrome steel. With the big liners on the bottom of the chute you need to get a Chevron cast into the top to push the feed out to the sides for the first little while and then as the chevron wears it will start to come back into the centre. This will make the wear life longer and more even on that piece. The

Wet milling - IKA
Wet milling with IKA's inline machines is a safe and efficient alternative to dry grinding. Dry grinding creates a lot of dust which causes the need for proper filtering systems.
