subject: Prompt Repair Of The Lining Plate Is Necessary [print this page] The examination of the suspension device requires a steady and firm installation when the crusher produces a great impact load during working. And it should be well lubricated as well. When in normal operation, it allows no start existing in the suspension device. Thus it must be installed firmly at the time of inspection. During the time of the crushers rotation, the main shaft would produce a positive-going or negative-going rotation, but the rotation speed is generally less than 10r/min. If it rotates too fast, it manifests that theres maybe something wrong with that device so it requires timely overhaul. When the conical bush and the fixed bush get seriously abraded, the path of the moving cone decreases thus the crushers productivity declines significantly. Then the prompt repair and replacement are essential.
As for the accessories like conical bush and bearing backing ring, the hardness difference as well as their own hardness is bound to be guaranteed required by the design paper. Since the suspension device is of great significance, besides planned regular maintenance, it must receive maintenance utilizing any production gap. Bolt is used for the purpose of separating the nut and the shell, which should be well kept with grease after maintenance. The nut is ought to be fixed firmly by the bolt in the main shaft. The suspension device adopts grease lubrication and it should be lubricated with clean grease after inspection. Whats more the lubrication grease should be added regularly in the process of the crushers rotation.
The replacement of the crushing liner. When its thickness abrades two thirds, theres crack in it or the discharge opening expands too large to be adjusted. At this moment, the fixed and moving conical liner must be changed. It can be divided into the following circumstances: 1.replacing the fixed and moving conical liner simultaneously. 2. changing only one of them 3.merely changing their under liners 4.only changing one of the under liners 5.just do some partial changing.
