Today, more and more manufacturers gangue grinder, then the user can choose how high-quality products from many manufacturers as well? It is necessary to do your homework in advance, in advance of major gangue grinder offer consulting, advance understanding. In fact, as long as customers have some tips when you do not bother to buy quality Coal mill, where three high mechanical for you a brief look at: 1, see the thickness, the naked eye can clearly see it, the thickness of the steel plate directly the relationship between the life of the equipment, we have had customers carry a ruler to measure. 2, look no assembly equipment inside the building large gangue grinder pictures, rotor shaft, hammer, and the thickness of the liner, because these parts are inside the machine, only to see no assembly is completed before we can see the quality. 3, see the details of the deal, this is more general, and can be seen welding, painting can be seen, and so on, as long as customers will be able to leave a heart to observe it. 4, the most important look at the test machine, customers do not go above a prototype test machine, because the prototype are certainly tuned more comfortable, and to test a large gangue grinder machine, just to try out the equipment producing large gangue smash machine prices, so as to see their quality. Coal mill equipment necessary to buy carefully selected, to be able to foolproof. 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 national standard, such as: Determination of manganese content GB / T 5121.14-2008, 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 after foundry when its Mn content is given, it is known, the standard steel processing, dubbed range of concentrations ranging solution c, then the measured absorbance values ??A, to a standard curve; the measured absorbance value of the sample solution and then you formulated, the concentration of Mn according to the curve obtained, 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.
