Cringe-Worthy Grain Crushing Methods Put to the Test

The purpose of grain crushing is to crack open the outer husk of the grain, exposing the rich center. Well-milled grain will leave the husk in tact, like the opening of a clam. This will make the grain bed more coarse in the fermenter or grain bag, which will allow the water to pass through and remove the nutrients you need from within.

Particle Size Reduction For Animal Feeds: Part 4

Particle size reduction in a hammermill occurs as a result of the impact between a rapidly moving hammer and a relatively slow moving particle. The particle breaks and is accelerated towards the screen. Depending on the particle size and angle of approach, it either passes through the screen or rebounds from the screen into the rapidly moving hammers again.
