Upper end of the Raymond mill roller assembly has gland and closures, easy to loose screw gland, grinding machine powder into the assembly chamber interior 1815 Raymond, roller stops rotating, cause Mill does not operate properly, bearing fever. Maintenance. Bearing in oil Raymond, seal damaged Raymond mill appears. If the seal is damaged Raymond 5, causing the bearing oil, ash, etc., will cause bearing oil, run the outer edge, bearing locking and so on. After much discussion and research, we Raymond machine grinding rolls heat treatment of the material itself. After heat treatment of the roller on the solution to the problem of high hardness easy to break. But there is a problem now, is that when we increase the hardness 3r2115 Raymond, Applied Materials is the composition of the material on the changes. After the composition changes, the higher the hardness of the casting, but this time a problem arises, the lower its toughness, easy to break. Raymond 3r, Shenyang Raymond, Yuxin Senda Ltd. Henan new Senda by heavy machinery. Henan new Senda Heavy Machinery Co., Ltd.
