Fault Diagnosis Criterion of China Raymond Mill from kuangshanposui's blog

More attentions are paid to machinery fault diagnosis because of modem Raymond mill industry's great scale systematized and automation. The breakdown of the main facilities will not only cause damages to machines, but also affect the normal production process, if no detection and elimination in time. Moreover, the breakdown will possibly wreck machines and kill people. In continuous producing system, if the main facilities cannot work well because of some problems, they will affect the working system of the whole factory and cause unimaginable economic losses.

The importance and evolution of fault diagnosis is introduced in the Ore Milling Equipment paper, and the following subjects are further expatiated, which include: l) The characteristics of fault and fault diagnosis; 2) The main fault, characteristic and method of fault diagnosis of the raymond grinding mill; 3) all kinds of methods to operate and monitor diagnosis with the fault to the raymond mill,On the basis of industrial practical application, the key subjects are as follows: fault of bearing and transmission of gear wheel, raymond mill 'bloated belly', In addition, the systematic design philosophy combined with monitoring, diagnosis and production process was put forward in this work, the system for the real-time operating mode and state recognition, online analysis and fault diagnosis was formed, and the systematic technological design frame was confirmed.

Working principle: This machine is a skeleton pattern raymond mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.
