Because of the high hardness and poor wear resistance of steel slag, the potential cementing property of steel slag can not be effectively exerted, and the utilization rate of steel slag. Is low. In order to improve the performance and grinding efficiency of steel slag powder, different grinding aids were added in the process of steel slag grinding in laboratory and …

Therefore, during grinding of slag in water, a disperse system based on calcium hydrosilicate (tobermorite) and calcium silicate develops. Calcium silicate, which is responsible for the binding properties of the material, is located in the surface layer of calcium silicate particles.

Basic oxygen furnace steel slag is a kind of cementitious material with low activity and hard for grinding. The objective of this work was to validate specious grinding aids F1 made in lab which was effective for the grinding of steel slag, thus enhancing the hydration properties.

The aim of this study is to evaluate the effect that the size of grinding media exerts on ferronickel slag milling efficiency and energy savings. A series of tests were performed in a laboratory ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling operation, …

Magnetic reseparation of steel slag results in improved grinding with the material exhibiting grindability intermediate between that of steel slag and OPC clinker after the same time of grinding. 13.4.1 Stability and other properties of slag blended cement13.4.1.1 Stability. SSBC paste specimens were inspected when cured.

In addition, the grinding efficiency and energy consumption of the above two grinding methods were also analyzed. The results show that, in comparison steel slag obtained by ball mill, the particle size(D 50 : 2.06 μm) of the steel slag obtained by the supersonic steam mill is smaller, and the particle size distribution range is narrower, and the particle is more uniform.
