On December 28, the consortium with Wuhan Institute of Building Materials (WIBS) as the lead party successfully won the bidding for the general contracting project of the production line in the processing area of Zibo Liuquan Limestone Mine's 2 million tons per year limestone mining project.

　　During the bidding process, Wuhan Institute of Building Materials won the trust of the owner with high-quality bidding documents and the most preferred design scheme. In the subsequent implementation of the project, Wuhan Institute of Building Materials will rely on high-quality design concepts and rich experience in project management, under the premise of ensuring the stability and reliability of production and use, using advanced technology and intelligent and energy efficient host equipment in the industry, to achieve the owner's requirements with higher than the national and industry design specifications of technical measures.

　　In recent years, Wuhan Institute of Building Materials has undertaken more than 150 sand and gravel aggregate projects, and has always insisted on continuously researching and developing process routes that fit the characteristics of the projects in the aggregate industry, and has always been in line with the domestic and international advanced technology, looking at the whole country and benchmarking internationally. Through continuous innovation and optimization of project management, it has led the continuous updating and breakthrough of technology in the sand and gravel aggregate industry, and established unique advantages, good reputation and leading position in the sand and gravel aggregate industry.

　　This project is an annual processing of 2 million tons of limestone production line invested and constructed by Shandong Kunyu Rock-Based New Material Technology Co., Ltd, containing limestone processing system, material conveying and storage, auxiliary production facilities and living and office areas. The mineral composition of the ore is simple, the average content of calcium oxide reaches more than 54%, magnesium oxide and other harmful components is less than 2%, it is a high-quality resource with good grade. According to 'Mineral Geological Exploration Specification Limestone, Cement Ingredients' (DZ/T0213-2020), the limestone ore in this area meets the requirements of industrial grade, and it is designated as limestone ore for alkali production. 0-80mm large material can be used as limestone ore for alkali production, 0-30mm material can be used as calcium stone or cement plant, and waste stone can be used as building aggregate or road repair, so as to realize the comprehensive utilization of mining resources. The project process adopts jaw + double-toothed roller crusher production line with a table time of 800t/h, and jaw + impact crusher production line with a table time of 800t/h.
