In the past 40 years, the international cement industry has made remarkable progress in technology, which is embodied in the development of new dry process cement production technology. The new dry process cement production technology has attracted the attention of the whole industry because of its high yield, high quality and low consumption. However, from the cement production line that some countries have put into operation, the product quality is poor, and cement production line with unstable production is also quite a few. In these enterprises, there are design problems, there are equipment selection problems, but also the management issues. But I think one of the most important problem is the preparation of raw materials, and the homogenization of raw materials, for cement plants, its importance is self-evident, especially the new dry process cement plant. In the production process of cement production from raw material mining to final cement production, the process of homogenization of components is actually carried out.

CHAENG(Great Wall Machinery Co.,Ltd) experts believe that the new dry process cement production must pay attention to the preparation of raw materials, pay attention to the homogenization of raw materials. This is an important guarantee for stabilizing the thermal system of the kiln and stabilizing the quality of clinker. In the production control, we should pay attention to the following points:

(1) Ensure homogenization effect of pre equalization yard.

The production department adopts the correct way of stacking and handling to control the quality of raw materials into the plant. A strict mining plan must be worked out for mining. The standard deviation is less than or equal to 2% ordinary NSP production line ingredients limestone CaCO3, the standard deviation of <2% clay;

(2) Homogenization operation must be standardized and carried out.

The factors affecting the homogenization of raw materialsmust be excluded, and the management system should be strictly enforced and regularly repaired, so as to ensure the homogenization effect of the raw meal storehouse. The standard deviation of CaCO3 for the raw material entering the kiln reaches below 0.2%;

(3) Intelligent precise proportioning.

The proportioning is related to the control target value and uniformity of raw materials, and directly affects the homogeneity of raw materials. X fluorescence analyzer, computer batching control system and high-precision feeding scale provide the basis for the accuracy of ingredients. In actual operations, we must strictly manage to make it play the biggest role.

In short, for the new dry process preparation of raw materials is very important, we need to strengthen the management in the production department work, improve the technical strength of equipment control personnel, the correct use of the homogenizing system, the quality of the raw material preparation is guaranteed.
