Abstract
Through cooperation study between Agricultural Engineering Research Institute (AEnRI) and Central Metallurgical Research and Development Institute (CMRDI) farm machinery spare parts recommended to manufacture from an advanced iron casting called austempered Ductile Iron (ADI). The main objective of this research is to redesign a horizontal impact crusher hammer manufacture from (ADI) alloy by casting technology. Both of the original and the new manufactured hammers were tested in the Laboratory and in the Field. The final results indicated that the new hammer produced a highest percentage of fine crushed particles compare with original one. The wear rates were 0.037 g/h and 0.023 g/h for the original and new hammer respectively. This means that wear rate decreased by about 38% when replaced the redesigned hammer instead of the original one.
