ABSTRACT: Bran is produced from other side the paddy hulling which its exploiting is used for the raw material of food livestock. Bran quality of result of paddy hulling in Indonesia most still not yet fulfilled the standard required by industry of food livestock. To be made by raw material of food livestock, bran need the process screening, so that productivity of raw material of food livestock specially bran become to lower. To overcome the the problems hence require to be made by hammer mill machine for bran produced from the paddy hulling machine. Research to start from phase of mechanism scheme work, machine component planning, fabrication, assembling, and machine examination. Machine use the electromotor with the power 3 HP; rotation 1600 rpm as driver. Rotation of motor by transmission to roller with V-belt. Rough bran to be refined feed into cavity between rotary roller (rotor) and static roller (stator). Result of machine examination can the function, with measurement produced a bran of the size maximal mesh 30 is 83%. With the existence of this hammer mill machine of bran, can improve the quality, productivity, and continuity of raw material of food livestock.
Keywords : bran, mesh, design, quality, productivity
