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, Raymond mill, 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 a higher ductility and impact toughness. High manganese steel with high wear resistance, although its hardness only HB210, but its yield point σs low clay mill, 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 beginning work, grinding ring around the spindle rotation, and the role of high pressure spring and centrifugal force, kaolin mill, close to the ring rolling mill, when the material to be ground into the grinding chamber, Raymond machine grinding ring from the blade shovel From feeding were rolling around the spindle rotation between roller and grinding ring, RCC after the powder with circulating air blower into the analysis machine, qualified powder-gas inflow whirlwind of powder is finished, large particles tablets regrinding of magnetic separation equipment circulating air blower to repeat the above process, milling machines, he 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. Pay attention to when buying a few of Raymond mill Raymond mill in various fields have a wide range of applications, for now the market is concerned, production milling machine manufacturers are more and more devices of varying quality. There are some unscrupulous businessmen to ultra-low price to deceive users, so the user has also brought problems. So when you buy a Raymond mill should pay attention to what it? The first step we have to Raymond mill manufacturer's reputation and customer evaluation for a assessment, which is the most important. The second step quality assurance Raymond mill, looking for a professional engineer to conduct a comprehensive inspection equipment, bolts and other small aspects also need to examine thoroughly; The third step is to make its service assurance, accompanied by the signing of the contract described as a voucher; the last is the price, because we have a special on the price before this had described in detail, there is not more talk about it.
