Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys. Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. Slag appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer. It might often be regarded as to become a combination of metal oxides and silicon dioxide. Common components of slag include the oxides of silicon, aluminum, and magnesium, as well as sulfur, which is always present. Slag also contains phosphorous, calcium, ash, remnants of flux materials such as limestone, and remainders of chemical reactions between the metal and the furnace lining. Slag is produced during the smelting process in several ways. Firstly, slag represents undesired impurities in the metals being smelted, which float to the top during the smelting process. Secondly, metals start to oxidize as they are smelted, and slag forms a protective crust of oxides on the top of the metal being smelted, protecting the liquid metal underneath. When the metal is smelted to satisfaction, the slag is skimmed from the top and disposed of in a slag heap to age. Aging slag is an important part of the process, as it needs to be exposed to the weather and allowed to break down slightly before it can be used. In slag crushing process, there are many euqipment used, like jaw crusher, slag crusher, grinding mill, belt conveyor. Zhengzhou Hongxing is the popular manufacturer of all types of crushers including slag crushers in China together with grinding mills and other mining facilities.
