Shale crusher hammer forging heating note the following five points: 1. Oxidation: Coal mill hammer surface heating easily combines with oxygen to produce oxide. Oxide not only hammer loss (heat loss for each 1% to 3 per cent of the total weight of the steel material), but also reduces the surface quality, but also to accelerate the abrasive wear. 2. decarbonization: Coal mill hammer when heated carbon surface is oxidized burning out, a phenomenon called decarbonization. Decarbonization result hammerhead excellent material surface, strength and wear resistance decreases. Decarburization depth just not exceed machining allowance. 3. Overheating: heating temperature exceeds the allowable temperature process specification range, causing the internal organization of gangue thick metal hammer mill, a phenomenon called overheating. Not only the mechanical properties of steel has declined and become overheated organization 4. burnt: metal high temperature for a long time and then heated in oxygen furnace gas will penetrate into the internal organization of the metal, causing the oxidation of grain boundaries and grain boundaries low melting point melting impurities, undermining the binding force between metal atoms and thus cracks in the forging process, this phenomenon is called over-burning. 5. Cracks: crack causes heating temperature is too high, too fast, and improper heating furnace and other equipment. If heated too fast or installed furnace temperature is too high, due to the steel table, where the temperature is too large the new shale crusher price, resulting in great stress, causing cracks. It must be used for this type of steel is heated slowly or be preheated. Shale is a hard, containing substances of new shale crusher model size mineral elements, in order to more easily extracted with a substance in shale, shale need a can crushing equipment, professional shale grinding mill is specially designed for shale. Of course shale mill is not only able to crush the new shale shale mill spot, a lot of hard material can be crushed, but is a little more for shale characteristics. Characteristics of shales is not the same, the nature of the different regions are not the same shale, shale with some areas of the mill will be able to crush the general good, but in some areas of the shale is sticky will appear, and some shale water content is great, and general mill crushing them with a sticky and too much moisture shale crushing difficulties, Hu blocking sieve and unable to crush the problem . The use of professional shale mill is not the same, three high mechanical (www.sangaofsj.com) produced shale crusher has the perfect solution to all these problems completely eliminate the sticky material containing moisture The problem can not be broken. The new shale mill Model Size | Shouning of new shale crusher | Three high mechanical provided by 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!
