The shredding of agro-residues, such as corn stalk, straw, wood sawdust and other herbaceous biomass, were investigated in this dissertation. According to the machinery mechanics of shredding, the components, shearing strength and pressive strength of the biomass were analysed in theory, which played a critical role during the shredding process. And the powder was examined by Scanning Electron Microscopy. It was founded that shearing,splitting and grinding force were appropriate for shredding biomass. The results also showed that primary shredding was the bulk shredding model, which was mainly affected by shearing and splitting force, therefore the curly knife and the straight knife were useful; while the fine shredding was the surface shredding model, affected by splitting and grinding force, and the straight knife useful.

本文以农林废弃生物质为研究对象，结合机械力破碎基础理论，从影响其破碎的化学组分和剪切强度、抗压强度等力学角度进行了理论研究，并运用扫描显微镜对破碎产物的微观结构进行了实际分析，结合二者得出如下结论：最适合生物质的施力方式为剪切力、劈碎力和磨削力；生物质粗破碎为体积破碎，主要受剪切力和劈碎力作用，刀片宜设计成弯口刀和单面直刃刀；细破碎为表面破碎，主要受剪切力和磨削力作用，刀片宜设计成双面直刃刀。

The wear mechanisms of the graphite pairs were examined based on the original image before and after sliding, the result shows that under air media, the graphite pairs works on the conditions of boundary lubrication and the wear mechanism is dominated by adhesion and plough wear, which is dominated by slightly plough wear under water environment.

磨损表面原始形貌对比分析表明，在空气中，摩擦副表面处于边界润滑状态，主要磨损机制是粘着磨损和犁削；水润滑条件下为轻微犁削；油润滑条件下，摩擦副表面处于为边界润滑和流体润滑状态，油中的减摩剂对试样表面有抛光作用。

The research results showed that resin bond could hold the self-sharpening diamond more tightly than ordinary diamond, for CSD diamonds have irregular shape, rough surfaces and many incurvated angle. Under the condition of the same grinding efficiency, the grinding ratio of resin bond grinding wheels made with self-sharpening diamond was 1.6 times as high as that of the grinding wheels made with ordinary diamond.

试验结果表明，由于CSD形状不规则，有许多凹入角和粗糙表面，树脂结合剂对CSD的把持力较普通金刚石强，所以在磨削各参数相同的条件下，自锐性金刚石砂轮与普通金刚石砂轮相比，其磨削比提高60%以上。
