2-The increasing of oval slots area decreasing the percentage of cut
length of less than 3.5 cm. While increasing the cut length of 3.5-10
cm and more than 10 cm of all crop residues under study.
3-The increasing of feeding rate decreasing the percentage of cut length
of less than 3.5 cm. While increasing the cut length of 3.5-10 cm and
more than 10 cm of all crop residues under study.
4-The increasing of drum speed increasing the percentage of cut length of
less than 3.5 cm and 3.5-10 cm. while reducing the cut length of >10
cm of all crop residues under study.
5-The increasing of moisture content decreasing the percentage of cut
length of less than 3.5 cm. While increasing the cut length of 3.5-10
cm and more than 10 cm 0f all crop residues under study.
6-The increasing of concave clearance decreasing the percentage of cut
length of less than 3.5 cm. While increasing the cut length of 3.5-10
cm and more than 10 cm of all crop residues under study.
7-Increasing the concave oval slots area decreased power
consumption and energy required.
8-Increasing the drum speed increased power consumption and energy
required.
9-Increasing the feed rate increased power consumption and energy
required.
10-Increasing the moisture content increased power consumption and
energy required.
11-Increasing drum-concave clearance decreased power consumption
and energy required.
12-The option condition for operating were conducted at 4 cm
