The production process of KR desulfurizer is introduced.By analyzing the defects of the whole process,the improved scheme of device is put forward.The results show that the improved production process can meet the demands of the particle size for desulfurizer,the vibrating screen is not appropriate for in production process of desulfurizer,and the circular hopper is more suitable for lime powder transportation than quadrate hopper.

This paper mainly introduces the projects of Qinghai lime production line and Mongolia’s lime production line with annual outputs of 100 000 tons both，and analyzes the optimization of the raw materials，process flow，equipment selection and installation.After production commissioning of the firing system，the paper analyzes the shaft kiln firing system.Finally，it summarizes the commissioning experience and proposes recommendations on further possible optimization.

By comparing the data of silica fireclay with different standards, this paper analyzes the effects of chemical compositions on high-temperature performances,and the analysis results of experiment data will be applied in the revision of the lasted editions of the silica fireclay standard.

Taking for example the active lime production line of rotary kiln,this paper introduces the key points of the random emission of dust in the production process of active lime,and proposes the controlling measures.

Taking a production line of calcium-based products with the capacity of 1.1 million tons as study object,this paper establishes and analyzes the resource comprehensive utilization scheme on energy conservation and emission reduction,which plays a guiding role in development of calcium industry.

In this paper,the current situation in using RH furnace refractories is summarized and its regular problems are analyzed.Solutions and measures are also given for an appropriate using this material in the long run.Furthermore,rational selecting materials at different positions in the RH furnace and the design are studied.

This paper briefly introduces the features and processing problems of solid wastes,and discusses the feasibility of solid wastes co-processing technology in cement kiln by comparing the national and international technologies.The result shows that the industrialization practice of the solid wastes co-processing technology in cement kiln can ensure harmless disposal and achieve the aim of emission reduction of solid wastes.

With the characteristics of low heat consumption,high quality,small occupation of land and high automation,double-shaft kilns occupy increasing market share in China.Control system is the main technological part of the double-shaft kiln.And control optimization is an important way to improve technology of the double-shaft kiln and guarantee the product quality.
