Extrusion load stress and grinding Raymond mill wear parts easy to make martensite cracks, when the eutectic carbides along the grain boundaries into a network, will promote its brittle crack propagation, residual austenite In this case the existence of the body to prevent the extension of a good crack, to the number on Raymond often need to replace the grinding rolls. Raymond roller mill wear parts are easy to wear, so it's useful life and its environment are closely related, so Raymond roller mill machine to suit different needs, requirements for surface condition of the roller are also different. Some of the work roll surface grinding Raymond, Roll Roll, Roll roll shape is cylindrical; some rolls and grinding teeth, only a rough roller surface, roll 4r Raymond called smoothing roll, roll ends light with a slight taper. Raymond mill roll: Raymond mill roller mill is the main part, Raymond will require uniform continuous pulverized material into the grinding chamber, the centrifugal force due to rotation, the roller swings out Raymond 3r, squeezing and grinding ring Raymond 6r, shovel blade materials sent between roller and grinding ring, due to the rolling mill rolls to achieve the purpose of crushing. Therefore, the loss in the long term operation of the roller is very large. Raymond is necessary to change the use of a few months after grinding stick, this is well known, Raymond grinding roller and disc liner material commonly used high chromium cast iron or nickel-chromium alloy, and such material is frequent breakage, resulting in The loss is very serious, especially discontinued loss, it is not possible to estimate Raymond machine _ Yuxin Senda (certified) _ Raymond Ltd.
