ScienceDirect Study on the particle morphology, powder
1. Introduction. Reducing the consumption of natural resources and enhancing the performance of cement and concrete are the two most important issues in the development of cement and concrete in the world today [1], [2].A powerful approach to address these problems is the widespread use of industrial wastes with potential 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.

Efficiency of high energy over conventional milling of granulated
Recently, Bouaziz et al. proved the unequivocal effectiveness of high-energy milling compared to conventional milling in achieving high rates of slag finesse [24].3. 4. Mechanical behavior of cement-slag pastes Fig. 10 shows the compression strength gain for slag paste cements for all milling conditions as function of slag milling time. The gain is measured with respect to the reference paste, which exhibits compressive strength of 52, 55 and 57 MPa after 7, 28 and 120 curing days.Efficiency of high energy over conventional milling of granulated

Utilization of Linz–Donawitz slag from steel industry for waste
The Linz–Donawitz (LD) slag is an industrial waste generated in Linz–Donawitz process of steel making. It is not gaining importance in construction industry because of its volume instability, and presence of excessive phosphorous and sulphur content. Suitable accelerated ageing and masking of harmful materials can improve the 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.

Copper slag as a potential source of critical elements A case
A large slag dump (approx. 40 000 m 2) is located adjacent to the smelting complex and contains approximately 1.5 Mt of slag. At present, the reprocessed slags comprise granulated fragments ranging in grain size from a few millimetres in diameter to predominantly powder-size due to granulation and/ or milling (Jarosítková et al., 2017; The present invention relates to a mill run slag slurry treatment process for ball milling and water washing of waste iron and steel slag and a device, which mainly solves the technical problems that the existing mill run sewage treatment process for ball milling and water washing is too simple, particularly can not carry out recovery processing for slag slurry, etc.CN1304119C Process for ball milling and water washing of

BOF Steel Slag: Critical Assessment and Integrated Approach for
During steel production, the impurities in the hot metal react with the fluxes forming the steel slag. Chemical constituents of this steel slag (SS) are relevant to iron/steelmaking or blended cement manufacture. Harmful impurities present in it, however, limit its recycling to these applications. Japan, Europe, and the US consume a significant understanding the effect of operating parameters, e.g., ball size, mill speed, media shape, and ball/powder filling, on the grinding efficiency of ball mills [29–35].Effect of Grinding Media Size on Ferronickel Slag Ball Milling
