Compound crusher helps slag recovery to reduce resource waste

Time:Apr 19, 2020 Author:Boleiro

a process for separating different products from steelmaking slag includes reducing the average particle size of slag from a steelmaking process into fine particle size material, and separating the fine particle size material into at least an iron rich product and a silicate rich product based on the differences between these products in at least one or more properties including magnetic

jan 01, 2003 therefore, the basicity of aod slag is lower than steel slag. moreover, aod slag contains much less iron than steel slag. hence recovery of iron from aod slag is not important. perhaps the most important characteristic of aod slag is that it contains a high amount of cr (2.5–4.3%) and some ni (0.2–0.45%).

oct 01, 2020 plate-shaped slag waste heat recovery system. shigaki et al , developed a new process for waste heat recovery from the slags. in this process, molten slag (above 1673 k) is solidified continuously on the water-cooled rolls to produce plate-shaped slags (temperature: approximately 1373 k, average long side length: 50 mm, average thickness: 7 mm).

recovery area, like construction waste, slag and tailing after metal smelting, etc. crushers can be used to recover some useful materials from those “waste” and reduce environment pollution. choose the right crusher

oct 14, 2020 the production process of bio organic fertilizer from distiller grains is mainly divided into fermentation and granulation of organic materials. the main raw materials are animal manure, domestic waste, dead branches and rotten leaves, biogas residue, waste bacteria, etc. food processing industry produces a lot of waste, which is a good raw material for organic fertilizer.

How it works: crushers, grinding mills and pulverizers

Jun 02, 2017 industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. during the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.

impact crusher is a crushing machine crushing by impact energy. sand maker is applied widely in the sand processing. what's the internal factors that affect quality and output of ball mill. cone crusher serve the community well by using new technology. something we should know before buying an impact crusher.

all aspects of crushing, ore conveying and screening operation and maintenance: discuss any type of crushers: gyratory, jaw, cone, roll, hpgr, impact, hammer, etc. crusher liner, lubrication, mantle, bowl, spider and all other components.ore transportation on conveyor belts and through classification systems such as vibrating screens, grizzlies and feeders.

Feb 05, 2021 municipal solid waste is also known as garbage, thrash and refuse refers to the solid wastes discarded by the public daily. currently, about 1.9 billion tonnes of msw are produced every year on a global scale, out of which nearly 30% remain uncollected by municipalities' waste management systems ( waste atlas, 2018 ).

for this strategy cycle the company has set an environmental target to reduce the share of recycled waste to 92% (without overburden, host rocks in mining, and previously accumulated waste). in 2020 the plant fully processed a 25 hectare slag dump, where 5 million tonnes of secondary resources had amassed. crusher for wooden waste . use
