The paper set up mechanics model of roll cylinder mill, inquired into crushing stress of materials by mill and materials clamp Angle and energy requirement problems.
The shortcomings are as follows: (1) Crushing will destroy stalks' mechanics properties, the good quality of lengthwise tensile strength can not be made the best of;
其弊端在于:(1)粉碎破坏了原料自身天然生成的力学性质,不能充分利用秸秆纵向抗拉强度较高的特点;
3
Since modern damage mechanics is not able to describe the crushing process of ice sheet accurately, it is fairly difficult to study crushing ice force using theoretical or numerical methods.
