Abstract: The energy consumption of cement production in China is relatively high. How to expand the production capacity of cement with low energy consumption has become a more and more important problem for cement enterprises. Through the optimization of new dry process cement production technology and skills The paper puts forward the concrete measures to solve the shortcomings in the cement production system and put forward the concrete measures to improve the production efficiency of the enterprises

First, energy-saving powder grinding technology and equipment

(1) Cement grinding system.

Which includes the advantages of low power consumption and high reliability, which is more widely used in the application of the roller press system and the pipe mill system. The roll press system has the advantages of low power consumption and high reliability. The system is a pre-grinding process The equipment is composed of high efficiency cage type separator, bag filter and tube mill. It is regarded as a typical example of high-tech optimization of traditional cement process.

(2) Raw material drying powder system.

Mainly Vertical  roller mill system and pipe mill system,Vertical roller mill system in the operation of the process is relatively simple, drying capacity is relatively strong, but also has the advantages of energy saving, with the rapid development of China's machinery industry, China has developed a new Generation of roller mill, which has the effect of energy saving more obvious, but also greatly improve the reliability of its application. The grinding mill system is suitable for most raw materials. It adopts the new TSL modular type separator, which has the advantages of strong reliability, simple process and so on. It greatly improves the production of the system and saves the production cost.

(3) Crushing technology and equipment. Up to now,

China's most advanced limestone single-stage crusher can achieve output from 80 ~ 1800t / h, in addition, for the broken process and difficult to break the technical equipment and materials have been maturing, basically to meet China's modern industry Development needs.
