Optimization and Performance Evaluation of Blender-Hammer Mill

Abstract

The principle of design by analysis was adopted for the design of this project. The methodology used was to scrutinize the common critical defects of conventional hammer mills and proffer possible solutions. The foremost components of the new blender-hammer mill were enumerated. The initial tests carried out on the new blender- hammer mill revealed that the mill is capable of performing same function that industrial huge hammer mills and the conventional hammer mills can perform in production of course, medium and fine particles.The results obtained after testing, showed that the crushing efficiency was between 83% to 96%, for dry maize and wheat respectively, which is quite satisfactory. Production of fine grains was achieved but coarse, medium and fine particles were still produced for further re-run for finer particle.
