| Steel slag is a kind of waste material generated by the process of smelting iron and steel. With the rapid development of China’s iron and steel industry, our country’s steel slag pile has also rapid growth. According to incomplete statistics, our country waste slag heap the stock has more than 11 million tons, but steel slag practical comprehensive utilization rate is only 10%. If the amount of storage of waste steel slag are not recycled, not only the storage of steel slag occupy the land mass, but also the heavy metal element loss from steel slag, which will cause serious pollution to the environment, and this kind of phenomenon seriously restricted the sustainable development of the iron and steel industry of our country. Therefore, the comprehensive utilization of steel slag has not only huge environmental benefits, but also huge economic benefits.This thesis discusses the development of steel slag grinding equipment, systematically contrasts to the traditional grinding equipment, analyzes the advantages and disadvantages of various kinds of grinding equipment, and demonstrates the horomill in advance in the applications of steel slag grinding. Two steel slag samples are carried out to do grinding experiment by our corresponding experimental system. The experimental results show that the physical properties of horomill grinding of steel slag powder are satisfied with national standard requirement, and can replace cement equal. The abrasion and power consumption are also lower than the traditional grinding equipment. These are also experimental foundation to develop large scale grinding steel slag horomill.In this thesis, through analysis, the structure parameters and technological parameters of Φ3800 grinding steel slag horomill are calculated, and the main structure are designed. Because the structure and main components are large and the loading is complex, finite element analysis is applied for the key components by ANSYS Workbench software. The stress and displacement distribution of the barrel, roller and compressive bar are obtained, from which the mill strength and stiffness of main components can be verified to satisfy with the use requirement. Above works provide strong foundation for the following research and application. |
