Benchmarking Production Line Independently Designed by Hubei University Tianshu Industrial Research and Design Institute of New Energy Materials -- Shangdong Zhongrun New Building Materials Co., Ltd 10000 Tons/day Fine Sand Aggregate Production Line Pass Through Environmental Protection Acceptance

On November 25th, 2018, Shandong Zhongrun New Building Materials Co., Ltd 10000 tons/day fine sand aggregate production line pass through environmental protection acceptance by Xuecheng Environmental Protection Bureau, Zaozhuang, Shangdong Province. The project is a benchmarking production line designed by Hubei University Tianshu Industrial Research and Design Institute of New Energy Materials. Except for the whole design of the production line, all supporting environmental protection equipment are manufactured by Wuhan TianshuDust Removal Equipment Co., Ltd.

Test Result of Dust Removal Equipment

The experts of the project acceptance evaluation team believed that the environmental protection examination and approval procedures of the project were complete and the environmental protection measures required by the environmental protection bureau of Xuecheng district had been implemented or basically implemented. The operating load during the monitoring period conformed to the acceptance regulations and the monitoring data were valid. Environmental management system had been established, with no pollution accidents during the construction and operation of the project.

Mr. Li Shiyong, President of Shandong Shunxing Cement Co., Ltd. and General Manager of Zaozhuang Zhongrun New Building Materials Co., Ltd, introduced that the project started in July 2017, and all the stones and waste rocks in the mining area would be processed into fine sand aggregates. The limestone resources in the entire mining area will be fully utilized and generate greater economic and environmental benefits, and the production environment will be clean with leading indexes, achieving the goal of energy conservation, emission reduction, and low consumption and high efficiency.

The production line adopts the multi-stage crushing system, semi-finished and finished product screening and conveying system, multi-variety finished product storage system, unmanned centralized collection control system, full-range negative pressure control system and new sound insulation noise reduction structure, roof planting design, material application, and many other domestic advanced and mature technologies independently developed by Hubei University Tianshu IRDI. Making full use of the stones and waste rocks, with 100% utilization rate of original ore, good apparent roundness of various grades of aggregates and machined sand, I Class loose stacking porosity rate. After the project is put into production, it would be a modern green sand aggregate production line with highly integrated, automated and large-scale mining, processing, storage and transportation.

Experts of the review and evaluation group believed that the domestic construction is highly dependent on aggregate at present, and its demand would continue to rise. It is urgent to explore a new development model to solve the contradiction between sand aggregate production and ecological protection. The specifications for the construction of green mines in nine major industries, including the sand aggregates, formulated by the Ministry of Natural Resources of China, will be released and implemented in the near future. In the future, all new and established sand and gravel aggregate mines will be constructed in strict accordance with the requirements of this specification, the same as the coal, metallurgy and nonferrous metals industries. At the same time, the registration system for sand aggregate products will be promoted, and enterprises will be encouraged and guided to choose green technologies and green products. The combination of Zaozhuang Zhongrun New Building Materials Co., Ltd. and Hubei University Tianshu IRDI has opened up a channel between traditional industries and green technologies, has played a very good demonstrating role in guiding green production and green consumption and it is worth adopting. Taking this demonstration line as an example, to establish an evaluation system for the green development of sand aggregate industry in Shandong province, carry out product identification for energy conservation and green sand production, and product certification of green production and green products, guide the transform of industry and enterprises from purchasing of scale and speed to pay more attention to quality and benefits. Carry out environmental label certification of the product's environmental performance and production process, and encourage to preferential purchase products that have been eco-designed or certified by the environmental label certification.
