Based on the principle of mechano - chemistry , the strong shock and crashing mechanical force produced by ls - 250 pulverizer can act to the surface of superfine carbon and white carbon particles during the process . the result of the experiment indicated that distortion and amorphism change occur to the surface crystal lattice of carbon particles , and the phenomena are prick up as the action time of mechano - chemical force 依据机械化学原理利用ls一250型流能粉碎机高速旋转的动齿工作过程中产生的强烈冲击、碰撞机械力，使其作用于超细石墨及白碳黑颗粒表面，检测表明，石墨粒子表面晶格发生畸变及无定形化，且随着机械力作用时间的延长而加剧。
