Utilization of Linz–Donawitz slag from steel industry for

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 Industrial wastes consumed by the preparation of building materials is a potential method to ensure the sustainable development. In this study, lithium slag (LS), as the by-product of lithium salts production, was treated by wet grinding process to prepare micro particles and used to expedite the early hydration of Portland cement (PC). The Preparation for micro-lithium slag via wet grinding and its

Resource utilization of slag from desulphurization and slag

The main components of slag tailings are similar to Portland cement. Superfine slag tailings powder (slag powder) with a specific surface area of 569.5 m 2 /kg and a free calcium oxide content of 2.96% was prepared by grinding the slag tailings for 30 min with a ball mill. The slag powder could be used as cement admixture (3) Within the The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.Energy-Efficient Technologies in Cement Grinding IntechOpen

Effect of Grinding Media Size on Ferronickel Slag Ball Milling

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 The objective of this study was to assess the feasibility of utilization of grinding aids (GA) in the granulated blast furnace slag (GBFS) powder production. The GBFS powders were prepared with different GA, and their grindabilities, fluidities, reactivities and hydration characteristics were investigated. The experimental results indicate that Effect of different grinding aids on property of granulated

Process for the production of Portland slag cement using granulated

Traditionally, Portland slag cement has been produced by inter-grinding cement clinker with granulated blast furnace slag in grinding mills (N. Patzelt, Finish grinding of slag, World Cem. Vol 10, 1993, 51-8). The traditional method and apparatus for using blast-furnace slag cement clinker production was patented in India in 1995 (2180/DEL/95).The slag from an electric arc furnace (EAF) and slag from desulfurization and slag skimming (SDSS) generated by steel mills have been used as a fine aggregate or concrete filling material inPreparation of composite micro-slag based on the
