Abstract
The research aim to improve the performance of hammer mill knives by study of some engineering factors concerning on grinding knives. The experiments of this study were carried out during the agricultural seasons from 2008 to 2010 using hammer mill for milling grains and some crops residual in Sakha research Center, Sakha, Kafr El Sheikh Government. The hammer mill used in this study with concave hole diameter of 5mm. The moisture content of grains and crop residual were determined. The original and developed knives from local materials were tested from chemical analysis, hardness and tensile test. These tests were carried out at Central Metallurgical Research Development Institute (CMRDI), Helwan, Cairo. Also the finite element method at applying force on knives to find the maximum stresses and suggest the best shape of knife edge (serrated or smooth) and knife tip thickness, which redused the induced stresses in the knife. The results indicated that; using finite element save time and money and the developed knife has more working life.
