Recently, Jinchuan Group has transformed the preheater, raw mill, coal mill, grate cooler and other systems of two new dry process cement production lines during the period of peak staggering production shutdown, paid close attention to technological innovation, broke through various technical barriers with the highest standards, the strictest requirements and the most practical measures, and completed the technological transformation efficiently. After the completion of the
transformation, the comprehensive energy consumption per unit product of the two new dry process cement production lines is lower than latest national standards, better than industry energy efficiency benchmark level, and the production capacity is also improved. The daily output of clinker in the dry process plant is increased from 1300t/d to more than 1600t/d, the capacity is increased by 26%, and the annual capacity is increased by nearly 80000 tons; the daily output of clinker in the No.2 dry process plant is increased from 2750t/d to more than 3200 t/d, the capacity is increased by 16.4%, and the annual capacity is increased by nearly 100000 tons. After the
transformation, the clinker production capacity of Jinchuan Group's two production lines increased from 1.2555 million tons to 1.488 million tons (according to the above accounting), and according to the enterprise's statement, the annual production capacity increased by nearly 180000 tons.
Environmental impact assessment aims to evaluate and express the impact of any available method on the environment in the decision-making process, and is an important method to ensure the survival of personnel in the environmental conditions. It is a method and system for analyzing, predicting and evaluating the possible environmental impacts after the implementation of planning and construction projects, putting forward countermeasures and measures to prevent or mitigate adverse environmental impacts, and tracking and monitoring. Increasing the production of
cement clinker by more than 10% is a major change and should be re-assessed. Then, is this project re-assessed?
