Effects of thickness and speed of blades of a hammer mill on capacity of corncob size reduction

Abstract

The objective of this study was to study the effects of thickness and speed of blades of a hammer mill on capacity of corncob size reduction. The experiment was conducted with fermented and non-fermented corncobs. The speeds of blades were 800, 1,000, 1,200 and 1,400 rpm. The thicknesses of blades were 3, 6 and 9 mm. The results indicated that fermented corncobs were more easily to reduce their sizes than the non-fermented ones. As the speed and the thickness of the blades were increased, the capacity of corncob size reduction was also increased. The most suitable speed and the thickness of the blades should be used at 1,400 rpm and 9 mm respectively.
