It has hundreds of history that people's observation for Ultrafine Mill Production Line and cement ingredients. When the construction emerged in the early period of 19 century, cement production has attracted people's eyes. Reynold once made predications from theory, later people discovered that the properties of cement production equipment worsened notably with the cellular damage of cement ingredients. In order to develop high-performance ships, we have to research the generating and development process. Many industrialized countries around the world begin to develop big ball mill that can emulate the practical working condition. Because the problem of cement ingredients is very complicated, much work still rests on the observation for various parameters' influence on experimental results and the damage of material microstructure and cement ingredients. By now, we still do not develop relatively complete physical model and mathematical expression. The equipment of cement production line is similar to cement ingredients.

Based on the current developmental situation, our nation will pit forward the specific requirements, development and goal for vertical cement. At the period of historic transformation period, for every cement worker, each cement plant is not only an opportunity, but also a great challenge. We have no choice, but grasp chance and meet challenge; otherwise, we will be obsoleted seriously. The implementation of our country's industry policy makes the vertical cement plant face three outlets, the first is out of the game, and switch to bulk cement station, grinding station, and cement products manufacturer; the second is to introduce new technology, and adhere to technical progress, also coexist with new dry method; the third is to exchange new dry process kiln with vertical kiln and generally join the new dry method.

At present, a group of science and technology project personnel are contribute to the cement research, and they summarize laws, set up models and accumulate data from massive experiments, in order to settle the problem of cement grinding wear under more complicated working conditions, they summarize experience from design, material selection and anti-cement grinding treatment process.
