Metallurgical slag disintegration in centrifugal impact

View More

Dec 05, 2015 In focus are issues of metallurgical slag disintegration in centrifugal impact crushers. The article shows the model of material breaking in the centrifugal impact crusher chamber. The scheme of force interaction between slag particles and the crusher chamber is developed considering spread inertia load. It is found how structural parameters of crushing machines are connected with the

Sep 15, 2020 The fresh slag-based GC was poured into the concrete form immediately and compacted by a needle vibrator. The working time of the fresh slag-based GC was in the range of 1 to 3 h with a slump of more than 200 mm. Standard concrete cubes of 150 150 150 mm 3 and cylinders of φ150 mm 300 mm were manufactured simultaneously. The cube

Jun 23, 2017 The chemical interaction of a typical slag of EAF with three different carbon sources, coke, rubber-derived carbon (RDC), coke-RDC blend, was studied in atmospheric pressure at 1823 K (1550 C). Using an IR-gas analyzer, off-gases evolved from the sample were monitored. While the coke-RDC blend exhibited the best reducing performance in reaction with molten slag, the RDC sample

TikTok slang: A complete guide to the meanings behind

Jun 26, 2020 Two different types of steel slag boulders were found: some were light in weight with more voids (more porous, see Figure 1a), those were used in wastewater treatment [18], and others were denser with less voids (see Figure 1b). The SSAs with the denser structure were used in this study. (a) (b) (c) (d) (e) (f) Figure 1
