STUDY THE EFFECT OF SOME OPERATIONAL FACTORS ON HAMMER MILL

The obtained results revealed that, it is recommended to use the hammer mill at drum rotational speed of 2250 rpm (33.56 m/s), grains moisture content of 10%, concave clearance of 5 mm and hammer thickness of 5 mm, to produce pelleting feed by increasing percentage of fine milled corn. ًًWhile to produce mash feed and commercial use can be achieved by using the mill at drum rotational speed of 1550 rpm (23.12 m/s), grains moisture content of 14%, concave clearance of 12 mm and hammer thickness of 1.5 mm, by decreasing percentage of fine milled corn.
