Raymond mill wearing parts rubber sleeve and its role

Raymond mill wearing parts are very clear, such as grinding rollers, grinding rings, shovel knife, etc., but there is a wearing parts may not give you attention, that is, the rubber sleeve, the first time I heard this name for the first time into this industry is also a stunned, Raymond mill wearing parts and rubber sleeve, what is he made of? In which position? What is the role of function? A series of questions continue to emerge in front of you, do you have a certain understanding of the mill sleeve? Let's unravel the mystery of the rubber sleeve.

Rubber sleeve does belong to the Raymond mill wearing parts, but because of its cheap price is often ignored, but the significance of the rubber sleeve is far more than its price so simple, rubber sleeve connected to the grinding roller assembly and the plum frame, play the role of shock absorption buffer to protect the role of the shaft, mill hosts have rubber sleeve mill rollers rotating to reduce the grinding roller assembly and the plum frame to reduce the force to reduce the wear and tear of the rubber sleeve is not expensive, but if there is no rubber sleeve, the rotating shaft is likely to be broken, the rubber sleeve is not a good idea. Rotating shaft is likely to fracture phenomenon, the seriousness of the entire assembly needs to be replaced, a rubber sleeve dozens of dollars, and an assembly down to less than a few hundred dollars, compared to which loss is greater is self-evident, because of the advantages of the price of the replacement of low-cost, but also be ignored by the majority of people.

Rubber sleeve is how to realize the role of shock absorption buffer? Raymond mill rubber sleeve and other materials are different, using special rubber wear-resistant material processed from the quality of soft wear-resistant, when the roller assembly rotates if the direct contact with the Plummer frame, the same as the contact of steel devices is inevitably stronger force, wear and tear is more serious, and the direct addition of the rubber sleeve material is softer, can be a very good link between the contact point of the force, to play the role of damping and buffering. There are mill host internal structure can be seen, the plum blossom frame and grinding roll assembly middle connection way divided into left and right sides, so each grinding roll assembly needs to be equipped with two rubber sleeve parts, 3R Raymond mill for example, the mill for the 3 grinding rolls need 6 rubber sleeve, 4R mill needs 8 rubber sleeve, and so on, Zhengzhou OCP Mining reminds us, has been such a lower price and easy to wear the rubber sleeve parts are better to more Be some, so that the production of serious wear and tear and no parts available to delay production.

Rubber sleeve in the milling production line is only the smallest and most inconspicuous wear parts, such as grinding rollers, grinding rings, shovel knife, etc. is the most familiar, different wear parts caused by the principle of action, the intensity of the different service life also varies greatly, we take the three most common wear parts as an example to analyze the service life of the selection of Raymond Mill accessories, for this three kinds of wear parts, shovel knife life expectancy is the shortest, each grinding roller is equipped with a Shovel knife, the number of shovel knife and the number of grinding rolls equal, shovel knife because of the need to continuously shovel up the continuous role of the material, and the original material particles of the shovel knife wear more serious, so comparatively speaking, the shovel knife cycle is the shortest; and shovel knife compared to the life of the rollers on the side of some longer, but not as good as the grinding ring, the rollers in the grinding of the material grinding ring at the same time the force, but also in the rotation of their own, and a larger force, and wear and tear is relatively fast; the grinding ring in between the three The service life of the longest, no longer need to replace, in the internal structure of the mill after the reconstruction of the equipment, grinding rollers grinding ring and other wear parts of the service life of a longer period of time, so the same Raymond Mill wear parts but the use of the cycle and very different, in fact, even if the same kind of wear parts such as grinding rollers due to the problem of the force will also be a single wear and tear of heavier, while the other several intact a case, so for a part of the parts of the wear parts must be regular and timely inspection, to avoid negligence due to minor failures. Therefore, it is necessary to check the wearing parts of each part regularly and timely to avoid the big loss caused by the negligence of small faults.
