Cement is the most basic building raw material, and the current development of our country has a great demand for the cement, but the resources, energy consumption, and environmental load are all very high. Especially the small-and-medium-sized dry cement enterprises whose techniques and management are not reasonable, and low producing efficiency and serious environmental pollution have a terrible influence on the sustainable development of the social economy. According to this situation, under the condition of sustainable development strategy, the small-and-medium-sized cement making plant is required to pay attention to the clean production and high producing efficiency.
The main content, objectives and technical route of cleaner effectiveness production technology practice are determined. Firstly, for the weak link of kiln system energy consumption and sewage serious, the corresponding technical measure is taken measure, so that its emissions and power consumption drop significantly and meet the national standards. The cleaner product comes true initially. Secondly, according to the efficiency principle of the high quality, high yield and low consume, the reliable high-tech equipment is chosen to improve production process. At the same time, the optimization using waste in the production of products is carried through. On the basic of fine filter mill technique, through the further optimization of the cement mill structure, grinding media distribution and technical parameters, the low cycle load grinding technology carries into effect to deal with the cement mill inadequate capacity and the poor adaptability to the original materials; Different process cement enterprises are evaluated by factor analysis and achieve the order of their cleaner effectiveness production level. The results reflect that new dry process cement production levels are better than traditional shaft kiln production and wet process, which tests the feasibility of factor analysis in the cement industry clean effectiveness production evaluation.
The small-and-medium-sized enterprises should keep sustainable development in the processing procedure. The environmental factor must be put in the first place, and great attention should also be put on the improvement of producing efficiency to combine those two factors together. That is to say, by eliminating pollution from the source to the end, Positive introduction of reliable advanced technology and key equipment, rational effective using of all types of waste resources to improve product quality reduce production costs, the enterprise achieves economic and environmental coordination.
