Abstract

The aim of present work is improving the performance of the crop residues shredder by study of some engineering factors concerning the performance of the affecting tool. The items to achieve the aim of the present study are:(1) Evaluation of shredder performance before development(2)Manufacture of cutting knives from local materials.(3)Shredder performance analysis in cutting of cotton stalks (4)Shredder performance analysis in cutting of rice straw (5)Cost analysis of cutting operation. From the above mentioned study, it can recommend the following points for farmer or producer or user following the mentioned order has all the choices according to the prevailing production conditions;1- The proper selection of new material leads to decrease the sharp edge angle of modified knives to 20o degree without deformation. 2- Maximum cutting efficiency for cotton stalks was 86.4 % at 1mm clearance distance.,20o degree knife edge angle and 1600 rpm cutting drum speed.3- Minimum fuel consumption rate for cotton stalks was 2.48 L/h at 1 mm clearance distance, 20o degree knife edge angle. 4- Maximum machine production for cotton stalks was 1.4 ton/h at following factors:5 mm clearance distance, at 20o degree knife edge angle and 1600 rpm cutting drum speed.5- Maximum cutting efficiency for rice straw was 45.6 % at 1 mm clearance distance.,20o degree knife edge angle ,1600 rpm cutting drum speed. 6- Minimum fuel consumption rate for rice straw was 3.51 L/h at 1 mm clearance distance, 20o degree knife edge angle.7-Maximum machine production for rice straw was 0.99ton/h at following factors: 1 mm clearance distance.,20o degree knife edge angle 1600 rpm cutting drum speed.8-Cutting operation cost is 27.5 L.E./h.
