  • Performance evaluation of a hammer mill during

    The performance of a hammer mill fabricated in Uganda was evaluated and the optimal performance conditions were determined The evaluation was done with screen hole diameters (S) of 15, 20, and 30 mm, hammer tip speeds (H) of 6812, 8181, 10217 m s 1 and hammer thicknesses (T) of 40, 50, and 60 mm for determination of energy consumptionThe hammer mill was most efficient with a hammer thickness of 5 mm, hammer tip speed of 8357 m s1 and screen hole diameter of 216 mm, both for energy consumption and flour GMD The achieved impact energy calculated per unit mass, were 08144 kWh t 1 , 11748 kWh t 1 and 1832 kWh t 1 for tip speed settings of 6812, 8181, and 10217 m s 1 respectivelyPerformance Evaluation of a Locally Fabricated
