The agricultural crop residuals are considered one ofthe most important
problems thatface the environmental life and farmers in Egypt. The
mechanical treatment (cutting or chopping and briquetting processes) is
the prima!)' step and suitable solution for solving this problem. So the aim
of the present work is to develop a local machine, that combining shear
and hammer mill theo!)l. The performance of investigated prototype was
evaluated under different parameters including drum rotational speed;
concave holes diameter and tools arrangement steps. The output
parameters taking into consideration prototype productivity, power
requirement, specific energy and particle size distribution (fineness
degree). The output evaluation was conducted on two different crops (rice
straw and corn stalks) with 9.0 and 8.4 w. b moisture content. Evaluate
the local chopping machine. lInder different stages of experiment to
determine the best position and arra"gement for new parts ofdrum. The
experiments of this study were carried out in the Department of
Agriculture Engineering, Faculty ofAgriculture, Menoufia University and
Agriculture Engineering Research Institute .The modified machine is
suitable for small farms by lowest cost and highest remaining percentage
for shredding wastes. The obtained results showed that, the disc mills are
responsible for cutting operation and the other jla"il knives supports the process to the cuttingforce.
