This paper compared and analysed formulas about wind load calculation of Chinese, American and Europe code. Then it was described in this paper that the meaning of formula parameters and similarities and differences of these calculation formulas. Finally this paper took a project of kiln structure as an example and compared the maximum axial force of columns and story drift of different codes.

The first domestic 600000t per year nickel slag powder production line of Shandong New Building Materials Co., Ltd. was put into production in December 2013. The project ,developed by Sinoma Technology & Equipment Group Co., Ltd., aimed at Ni-Fe alloy smelting slag “zero discharge”, developing circular economy, protecting ecological environment, energy saving and emission reduction. Currently this production line runs stably and reliably. Its technical index fully meets the design requirements and the product performance is excellent. Thus this production line has created good economic benefits and filled the gap of domestic roller mill in Nickel iron smelting slag powder processing field.

EHS is the abbreviation of Environment, Health and Safety. EHS management is increasingly important in foreign cement projects. The environment, health and safety are managed systematically through environment factor identification, making EHS management plans, training and publicizing, continual improvement, etc. At present, most of domestic companies don’t understand the EHS management enough. EHS management system lacks systematicness and continuous improvement. Companies need deepening understanding, total participation, plan improvement and seriously implementation, thus the EHS can fully develop its actions. Only put EHS management into routine work , it can produce actual effect.
