        Key special projects of national key R & D plan      

The project "collaborative preparation of low cost cementitious materials and application technology with bulk industrial solid wastes" was developed by Led by China Academy of new materials After more than half a year's preparation, and after several rounds of rigorous expert review, defense and fierce competition, the company, together with 10 top scientific research institutions and enterprises in the field of solid waste recycling, including Wuhan University of technology, Hubei University of technology and Beijing University of science and technology, was finally won in April 2020 National key R & D plan "solid waste recycling" key special project This indicates that the national competent department and industry highly recognize the core competitiveness and application demonstration role of our company in the field of solid waste recycling.


       Key special demonstration line put into operation

On May 31, our company developed and designed One of the demonstration lines of the national key R & D plan "solid waste recycling" ——Tongguan Jian'an new environmental protection building materials technology Co., Ltd. has officially put into operation a new filling cementitious material project with an annual output of 700000 tons (including mortar line transformation).

The project takes the water quenched slag of general industrial solid waste as the main raw material. Through material design and innovative production technology, the new cementitious material produced can completely replace cement for underground cementation filling. Compared with cement, the consumption of cementitious material is reduced by less than 50%, the actual filling cost is greatly reduced, and the utilization of tailings can be increased.

       The filling material production line of the mine has large capacity, advanced technology and high degree of automation, which meets the needs of low-cost and high-performance cementation filling in eight mines of Tongling Nonferrous Metals Group Holding Co., Ltd., which is the owner of the mine. It solves the two major problems of domestic mine filling with high sulfur content and ultra-fine tailings cementation filling. It can save a lot of filling cost for Tongling Nonferrous Metals Group Co., Ltd. every year and solve the problem The problems of tailings discharge and mine safety are discussed.

During the implementation of the project, the project team worked overtime to optimize the scheme. On the one hand, it paid attention to the epidemic prevention and control, and on the other hand, it paid attention to the resumption of work and production, One month ahead of schedule Trial production! Tongling City, Anhui Province Pilot project of "no waste city" After the project is fully completed and put into operation, it will greatly improve the disposal capacity of general industrial solid wastes such as smelting waste slag and beneficiation tailings in Tongling City, which is of great significance to mine ecological environment governance in Tongling City.
