the market, overcapacity, high cost and tightening of double carbon constraints, the cement industry is experiencing a profound survival test. The profit margin of traditional cement production has been continuously compressed, and domestic enterprises are facing a large area of losses.
How to revitalize the existing assets and open up the second growth curve has become the direction that countless cement enterprise operators are struggling to explore.
In this context, relying on the existing grinding equipment in the plant area, the preparation of ultra-fine mineral admixtures from industrial solid wastes such as slag, steel slag and fly ash has become the preferred path for low-cost transformation of cement enterprises, and the heat continues to rise.
Industrial solid waste ultra-fine powder track has outstanding advantages: there is no need to add a large amount of heavy assets, reuse the original grinding system, and activate the idle equipment capacity; solid waste raw materials are widely available, which greatly reduces the cost of raw material procurement, and at the same time realizes the policy dividend of solid waste recycling; By virtue of micro-aggregate filling effect and pozzolanic activity effect, high-quality ultra-fine powder optimizes the particle gradation of cementitious materials, improves the compactness and durability of concrete, and has a broad market application scenario; Without high temperature calcination in the production process, the energy consumption and carbon emissions are far lower than those of the clinker production line, taking into account the economic benefits, environmental benefits and policy compliance requirements, so as to truly realize "turning waste into treasure, turning ash into gold".
But under the beautiful path, the practical problems on the road of transformation are equally prominent.
Many enterprises have encountered many problems after launching solid waste ultra-fine powder projects: the power consumption of grinding system remains high, the increase of production is not effective; the powder particle gradation is unbalanced, the activity index is not up to expectations; the grindability of different types of solid waste is quite different, and the original mill liner, bin length and grinding body configuration do not match; The powder selection process is not properly regulated, resulting in large fluctuation of fineness and unstable product quality; the multi-solid waste synergistic grinding process is not accurate, resulting in high trial production cost and delayed stable mass production. These grinding technology card points directly determine whether the project can be profitable and sustainable.
In order to solve the common problems in the industry, China Cement Network is scheduled to hold the 16th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 1st Solid Waste Comprehensive Utilization and Fluidized Solidified Soil Development Conference in Wuhan, Hubei Province, from December 3 to 4, 2026. Zou Weibin, a senior consultant of China Cement Network and a practical expert of cement grinding in China, was invited to the conference to share the experience, focusing on the first-line practical pain points of industrial solid waste preparation of ultra-fine powder. New opportunities are hidden in the
crisis, and the stock grinding production line is the core chip for the transformation of cement enterprises. If you want to avoid detours and make the solid waste ultra-fine powder project into a profitable new sector, this dry goods sharing should not be missed.
