By contrast months of sales, in the form of coal gangue crusher has been slow rotation, in order to improve the company's competitive strength, three high mechanical decided at the lowest price return customers for their support. All models are gangue grinder sold at cost, welcome new and old customers to factory tours. Gongyi City, three high Machinery Plant is a professional production of coal waste grinder manufacturers. The main products are gangue grinder, shale mill, a large two-stage crushing gangue crusher equipment Direct selling, construction waste shredders and other equipment, a wide range of models complete. Coal mill is now very popular in the market, more and more manufacturers gangue grinder. Coal mill on the market now say their high manganese steel hammer, but in the end Hammerhead not contain manganese, manganese number containing manganese content is not up to standard, it is not by the eye can see out. Although the manual device that has the information content of manganese hammer. But only genuine factory technical department know. So how should we measure the content of manganese in it, the bottom three high mechanical teach you a method. You can find the relevant GB large crushing gangue equipment accessories, such as: Determination of manganese content GB / T 5121.14-2008 crushed gangue large equipment manufacturers, you can find detailed answers you need, and there are very detailed steps. Want the real measurement accuracy, you also need UV-Vis spectrophotometer. In fact, we choose the foundry when its Mn content is given, known, after the standard steel processing, dubbed a series of concentration c ranging solution and then measuring the absorbance values ??A large crushing gangue equipment, making a standard curve; and then the sample solution measured absorbance value you formulated, according to the curve obtained concentration of Mn, Mn content of the sample can be calculated. In fact, the formula is A = εbc, A is your measured using a spectrophotometer, standard steel c is known, can make Ac curve. b- liquid layer thickness, ε- molar absorption coefficient may be inferred from the above equation is not good. But in practice it is really convenient. But there are a lot of customers will find the content of manganese in the hammer does not matter, as long as the wear and durable enough hammer. Large crushing gangue equipment manufacturers, large crushing gangue equipment, provided by three high mechanical Gongyi City, three high mechanical plant. Machinery Factory of Gongyi City High (www.sangaofsj.com) strong, credible, in Zhengzhou crushing grinding equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the three high mechanical and you hand into the brilliant, for a better future!
