Abstract

The main objective of this work was to performance evaluate for locally made small machine for faba bean crushing at moisture  content of 9.5 %  db. The performance of faba bean crushing machine was evaluated at different hammer drum speeds ( 1000, 1250, 1500 and 1750 r.p.m ), feeding rates ( 60, 90 and 120 kg / h ) and sieves holes diameter (2, 4 and 6 mm),were evaluated on the basis of curshing productivity (Mg/h), efficiency machine (%), total energy consumed (kW. h /Mg), Faba bean mean particle size % . The results indicated that the highest productivity was 118 kg/h and productivity efficiency 99 % obtained at 1750 r.p.m hammer drum speed , 6 mm sieves holes diameter and 120 kg / h feeding rate. The best result for crushed faba bean particle size was obtained at 1750 rpm, 2 mm sieves holes diameter and 60 kg/h feeding rate. While the minimum specific energy 7.50 kW.h /Mg was obtained at 1750 rpm, 6 mm sieves holes diameter and 120 kg / h feeding rate.
