Bulgur milling using roller, double disc and vertical disc mills
The roller mill had the highest milling yield (99.19%). Smooth and glassy particle surface was obtained due to the sharp-to-sharp operational principle of the roller mill (cutting effect). The quantity of coarse (/2.20) bulgur particle was higher than that of middle (2.20/2.00) and fine (2.00/0.50) bulgur particles.
