Performance Analysis of a Modified Laboratory Hammer Mill

Performance Analysis of a Modified Laboratory Hammer Mill

Oct 15, 2020 The modification in design of the hammer mill focused on the hammer pattern and arrangement whereas the performance analysis was conducted based on the average particle of bambara nut, cassava, and maize samples. The average particle sizes of the samples were compared to those produced with standard hammer mill and burr mill. The result shows that although the three
