| Abstract | ||||
| The main objective of the present work was to study and evaluate some engineering factors affecting date pits crushing for small locally made crushing unit at moisture content of 7.75 % db. The performance of date pits crushing unit was evaluated at different cylinders speeds (150, 250, 350 and 450 rpm), clearances between cylinders (zero, 1 and 2 mm) and opening feed areas (30, 37.5 and 45 cm2). The results showed that the highest productivity was 822 kg/h obtained at 150 rpm cylinder speed, 2 mm clearance between cylinders and 45cm2 opening feed area. The best result for crushed date pits particle size was obtained at 350 rpm, 0 mm clearance between cylinders and 37.5 cm2 opening feed area. While the minimum specific energy 1.11kW.h/Mg was obtained at 150 rpm, 45 cm2 opening feed area and 2 mm clearance between cylinders. | ||||
