摘要：在世界人类文明的发展历程中，文字的出现是文明社会出现的标志，而文字要想发挥其传承人类文明的作用又要依赖于记文字的载体。我国古代历经了在甲骨上刻文、在青铜上铸字、以及简牍（竹简）成册和绢帛书卷等等漫长的进程，最终在东汉时蔡伦改进发明了最为简洁方便的文字载体——纸。纸与其他的古代所使用的文字载体相比较，具有无法比拟的优越性能。甚至可以说，纸张的出现是社会文明载体发展史上划时代的革命。48440
锥型磨的基本作用是通过机械作用使纤维形态发生变形；首先是纤维的初生壁和次生壁产生位移，接着发生初生壁和次生壁的破裂，然后纤维吸水润胀、切断、细纤维化（即分丝、起毛等），最后使纤维具有良好的柔软性和可塑性，提高其结合力。
未经磨浆的纸浆浆料中含有非常多的纤维素。由于纤维长而粗。表面非常坚硬光滑有弹性，纤维的表面积小且缺乏结合性质的，如果不通过研磨纸浆用来直接复印纸，在网上很难获得匀称分布，纸张是疏松多孔时，表面将粗和易于起毛，接合强度非常低，纸张的性能是非常差的，因此它不能满足使用。而经过磨浆处理的纸浆浆料所出产的纸，其组织紧密而均匀，有足够的强度，可以满足基本使用要求。所以，锥型磨的作用就是使纸浆经过磨浆设备的处理后，使其纤维具有良好的可塑性和合理的尺寸，并且大大的提高了其细纤维之间的氢键结合力。另外，磨浆设备还能够使各种各样的原料、辅料、添加剂均匀的混合。

The Overall Design of The Conical Mill
Abstract: The development course of human civilization in the world, the words is a sign of civilization appeared, the text if you want to play a role of its heritage of human civilization will depend on the carrier of the written text.
In ancient China experienced in oracle, carved on bronze hand type, and bamboo slips into and silk bamboosilk volume, etc. A long process, the final was improved by CAI lun invented in han dynasty is the most convenient concise text carrier - a piece of paper.
Used in paper and other ancient text carrier, has the incomparable superiority of performance.
So far as to say that the emergence of the paper is the carrier of social civilization in the history of epoch-making revolution.
Without pulping, pulp contains quite a lot of cellulose.
Because the fiber is long, thick, the surface is quite smooth and elastic, fiber surface area is small and lack of combination of performance, if the paste used for directly writing without pulping are symmetrical distribution can be difficult to obtain online, after the paper is porous, the surface will be rough and easy to pile, and the bonding strength is very low, the performance of the paper is very poor, so can not meet the use.
And after pulping process of pulp produced by the paper, the organization tightly and evenly, have enough strength, can meet the basic requirements.
Pulping equipment, therefore, the role is to make the pulp after pulping equipment processing, make the fiber has good plasticity and reasonable size, and greatly improve the hydrogen bonds between its fine fiber binding force.
In addition, pulping equipment will also be able to make all kinds of raw materials, accessories, additives mixed evenly.
Key Words: the pulping machine; coupling; key shaft; fiber
