Recently, good news came from the construction aggregate machine-made sand production base of Qianyang Conch Green Building Material Recycling Industrial Park, which will turn waste from cement production into treasure, with an estimated annual output of 1.5 million tons of aggregate and machine-made sand, and an annual "recovery" of 120 million yuan for enterprises.
It is understood that the project of Conch Green Building Material Recycling Industrial Park in Qianyang County was selected as the Key Construction Project Plan of Shaanxi Province in 2023. The total investment of the project is 1.6 billion yuan , covering an area of about 420 mu. Six sub-projects, including the technical renovation project of SCR denitrification of clinker line and the project of machine-made sand with an annual output of 5 million tons of building aggregate, will be constructed .
In the production base of aggregate machine-made sand, only a large truck transported aggregate and machine-made sand to the construction site for use as building materials. It is understood that the construction aggregate machine-made sand project started construction in May last year, and the first phase was completed and put into operation in May this year, with a total investment of 400 million yuan, with an annual output of 1.5 million tons of aggregate and machine-made sand. The project is mainly to produce building aggregate and machine-made sand by using the leftovers of limestone to produce cement, so as to improve the utilization rate of limestone and save energy.
"In the past, we discarded all these leftovers, resulting in a waste of resources." Zhang Hongbin, a staff member of Qianyang Industrial Park Management Committee, said that the project is to make use of the leftovers of cement production, no waste, no waste discharge, closed transportation, no raw materials, directly into the crushing and processing production line, then into the silo, and then transported to the construction site, without pollution.
In order to actively respond to the national environmental protection policy and implement the concept of green and low-carbon development, China Cement Network will hold the "2023 Cement'Double Carbon 'Conference and the 10th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference" in Zhengzhou, Henan Province, from September 12 to 13, 2023. The cement industry is moving towards a low-carbon, more energy-saving and greener high-quality development.
At the same time, the medal ceremony of "2023 Advanced Enterprises of Double Carbon in Cement Industry" and the "Double Carbon" Equipment Exhibition will be held. After the meeting, we will also organize a visit to Jiyuan Zhonglian Cement Co., Ltd. "The world's first production line of carbon sequestration auxiliary cementitious materials and low-carbon cement from flue gas CO2 of steel slag capture cement kiln".
