Technical knowledge grinding ring of Raymond recently found that many users complain Raymond roller mill in life is too short rings, and does not take long to be broken, and that it makes them an illusion that the manufacturer In order to be the cheapest product earn the maximum benefit, the use of inferior steel production roller mill ring. As everyone knows, in Raymond is in accordance with the grinding roller and grinding ring pressed against each other in order to produce the required product, so the grinding roller and grinding ring of material are generally of high manganese steel and other wear-resistant materials. Because often pressed against each other, so the damage of time to be faster. For example, the production process grinding ring on it, it is 50SiMn made of steel, high manganese steel is a wear-resistant steel, high manganese steel water after treatment may be tough to get higher ductility and toughness. High manganese steel with high wear resistance, although its hardness only HB210, but its relatively low yield point σs, σb only 40%, so it has a higher ductility and toughness. High pressure suspension mill within the host, the roller hanger on fastening a 1000-1500 kg pressure hyperbaric spring mobile crushing station. After starting work Zhengzhou mill, grinding ring around the spindle rotation, and the role of high pressure spring and centrifugal force, keep grinding ring rolling, when the material to be ground into the grinding chamber, Raymond machine grinding ring by the shovel blade into place between roller and grinding ring rolling around the spindle, RCC after the powder with circulating air blower into the analysis machine, qualified powder-gas inflow whirlwind of powder is finished, particles tablets to fall back regrinding magnetic separation equipment circulating air blower to repeat the above process, it entered the Wind bag filter purification. To guarantee stable output and fineness. So grinding ring to go through the ring blanks - roughing - Heat treatment - treatment finishing these few programs in order to avoid grinding ring wear a short period of time a little. Raymond machine failures tips: Raymond machine milling equipment as a professional, a lot of the necessary equipment for raw material production plant, can complete a variety of materials processing and production, it requires a lot of fertilizer over the flour mill in so if there is some aspect of mishandling milling machine parts, the device is likely to malfunction, which delayed production mill, here to share some of the common reasons for failure and approaches with you. First, if the work process Raimundo, we found no powder or yield a lower than normal level, and this time you should consider whether or not the powder does not adjust well, because the powder is not good enough if the seal, it will make has been finely ground powder suck back; of course, there may be more serious damage to the blade, so that the material to be machined is no way to scoop up all this time you will need to carry out the relevant checks, powder and blade are Check the focus, if we find the powder is not sealed related adjustments will be carried out, if the blade wear is relatively large, so this time we need to change a new one. Second, Raymond machine can process a very delicate powder, if the process out of the powder found in processed fairly thick, or too thin, so this time we should consider whether or not analyze machine problems, and if this place goes bad, action would not achieve the grade, so that process out of the powder either too thick or too thin. There may be inadequate fan capacity, which will result in processing out of the powder is too thin or too thick, this time on the need to import wind turbine blades and adjust the opening of the replacement. Third, Raymond appear larger in the production process is not normal noise or vibration occurs, this time we should consider whether or not the material hardness strong, resulting in a greater impact, but also need to consider whether or not bolt loose, These will produce noise, but the solution is to adjust to the quantity, if it is material hardness is too high, you can consider some of the feed particle size reduction.
