One of the operations in particulate processing which has an ancient history and a widespread use is granulation. Granulated compost fertilizer was granulated using the drum granulation method under different level of drum filling. Filling of the drum ranged from 5 to 10% (v/v). The effect of filling of the drum on some physical properties granulated compost fertilizer including: useful granules, granules size, crush strength, mass of the granules, bulk density, angle of friction and angle of repose are investigated in the present study. Result indicated that with the increasing of drum filling the percentage of useful granules, crush strength, bulk density, angle of friction and angle of repose increase from 64.97% to 78.82%, 34.32 N to 36.69 N, 745.585 kg/m3 to 762.729 kg/m3, 25.56º to 27.93º and 11.38º to 12.52º, respectively. Also the average size of granules decreases from 10.28 mm to 9.45 mm.
