Abstract

The experiment was conducted to evaluate the effect of sieves holes anddifferent types of crop grain on some mechanical and volumetric of hammermill properties attached with the grinding process using two levels of diameterfor the sieves holes included 2.5 and 4.5 mm with three types of crop grainincluded barely, sorghum and maize, Specific Capacity and specific energy andthe volumetric properties, Average particle size, standard deviation were studed.The experiment carried out using complete randomized design (CRD), withthree replications in college of Agriculture / University of Diyala 2011- 2012.The Results were showed the fallowing: increasing of sieve holes changediameter from 2.5 to 4.5 mm resulted a lower significant effect in the Specificenergy and a significant increase in specific Capacity and Average particle sizeand standard deviation. Types of crop grain got significant effect on specificCapacity and Average particle size and no significant effect in specific energyand standard deviation. the interaction between factors led to lower Specificenergy 0.127 kw.h/kg with hole 2.5 mm and sorghum and the lower Averageparticle size 0.765mm and lower standard deviation 0.990 with hole 2.5 mm andmaize and the highest Specific Capacity with holes sieve 4.5 mm and sorghum.
