Hammer crusher, also called hammer mill crusher, is one of the major tertiary crushers for brittle materials in metallurgy, building material, chemical engineering and hydropower like limestone or coal, etc.
Charcoal briquette machine is also known as charcoal briquetting machine, charcoal ball press machine, or charcoal pressure ball machine.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
Aluminum dross is a mixture of aluminum metal and aluminum oxide. The increased amount of ash is a problem, since it leads to an increased loss of aluminum, It requires its processing and recycling. Therefore, reducing the aluminum slag is one of the most important tasks of any foundry.Read More
Aluminum saline slags are produced by the secondary aluminum industry and formed during the aluminum scrapdross melting processes. The amount of saline slagRead More
Nov 27, 2020018332Dephosphorization has always been a challenging task in the steelmaking process. In the traditional studies, CaO-based steelmaking slag was usually treated as a homogeneous liquid phase to analyze the dephosphorization equilibrium between molten slag and hot metal slagmetal. In fact, the slag shows a coexisting state of both liquid and solid at steelmaking temperature.Read More
Currently at plants producing and processing aluminum and its alloys casting methods, produce large amounts of aluminium salt slag. The disadvantage of this method is the presence of fine environmentally dangerous waste product containing valuable components metallic aluminumRead More
the melting of aluminum scrap that is coated with plastic. Salt slag processing emits hydrogen and methane. Solid wastes from the production of secondary aluminum include particulates, pot lining refractory material, and salt slag. Particulate emissions, possibly containing heavy metals, are also associated with secondary aluminum production.Read More

Apr 04, 2012018332Common slag treatment process in Japan is shown in Figure 4.4.12 81.About 80 79 of BF slag is quenched by water spray and the quenched BF slag sand produced is used mainly for cement, concrete and civil engineering resources.The rest is cooled by field air cooling and the slow cooled slag is used as a resource for road construction, concrete coarse aggregate, and so on.Read More
Nov 23, 2020018332Aluminium ash and slag is the product of the molten slag produced in the electrolytic aluminium or casting aluminium process after cooling and processing. According to the investigation, the production of aluminum ash and slag accounts for about 7 to 12 of the recycled aluminum output, and the metal aluminum content is between 10 and 30.Read More
Complex for Crushing and Sorting slag metal production Source-material specification. The line is designed for following source material parameters Material to be processed blast furnace slag Mass volume not defined, supposed to be 2.4 tons m3 Bulk material weight from 1.2 to 1.4 tons m3 Resistance to pressure from 60 to 100 MPaRead More
On-site slag recycling. Slag processing, or also referred to as bottom ash recycling or IBA recycling, and metal recovery on your site are the first steps in the range of services that Recco offers.. We engineer and manufacture a customized installation for temporary processing built up and installed from modular machinery or install a permanent system.Read More
The invention is directed to a process for extracting a metal from a slag containing said metal, wherein the liquefied metal-containing slag is heated in at least one electric arc furnace 1, 2.In order provide an improved method for recovering especially copper from slags, the invention provides that the metal-containing slag is heated in a first furnace 1 constructed as an AC electric ...Read More
Our range of services includes, but is not limited scrap yard management, finished or semi-finished product services, melt shop services, logisticstransportation support, and slag processing. Founded more than a decade ago, Scrap Metal Services is a leader in the industry, prioritizing recycling and environmental safety, and handling all ...Read More
Slag is a by-product of the smelting process. Most slags, because they are composed primarily of oxidized, glassy material, are not as significant a potential source of metals released into the environment as mine wastes and mill tailings.Read More
Based on this observation, the slag minimum refining process SMP, low slag process LSP, zero slag process ZSP and slag recycling process SRP were developed in the 1980s. After the desiliconization and dephosphorization processes, the low-silicon hot metal is charged to converters, the main tasks of the converter operation were reduced ...Read More

SLAG PROCESSING. After the slag has cooled at processing site, by magnetic means metal from the slag is seperated. The metal is then further processed and transported back to the melt shop. The clean, sized metal is recycled as part of the furnace charge.Read More
May 31, 2020018332Slag inclusions can also occur if the welding speed is too fast. Likewise, slag inclusions happen if the pool is cooled down too early, or if the rod is not suitable for the process. The slag may also become embedded or entrapped within the welded metal if it does not surface to the top and cool as a protective layer.Read More
the process needs a large amount of thermal energy. The end product of the alumina plant is a dry white powder that is the feedstock for aluminum smelting. 2.2 Primary Aluminum Production Throughout the world, primary aluminum is still produced by the electrolysis of alu-mina in molten fluoride salt.Read More
Oxygen is injected to remove impurities and other dissolved gasses during the melting process. As the metal melts, slag forms and floats to the top of the molten metal the slag, which often contains undesirable impurities, is removed prior to tap out the process of removing metal from the furnace.Read More
Slagmetal reactions Slagmetal reactions are very important in the production of clean metals eg. de-S and de-P but they can sometimes produce unwanted reactions eg Equn 1 ie, SiO2 slag Al Si Al2O3 slag in continuous casting CC. For steels containing gt1 Al this reaction makes the steels virtually un-castable by CC.Read More
