3. Check whether the materials are piled up and block the grinding mill. If the materials cannot be discharged, it will cased the vibration of the grinding mill. So the material should be deposited in time. 4. Check the situation of the roller and ring . If the roller and ring are badly worn, which also the cause of vibration and noise.

D. Romahadi et al., Classifier-Coal Mill Damage Detection using Vibration Signals Analysis 177 problems with the spectrum. Fig. 3 showed the Classifier-Coal Mill machine being measured. There were three main components, namely motor, gearbox, and rotor. The motor was on the top and was connected to the gearbox via the

Equipment that is showing excessive vibrations will most likely not achieve the expected lifespan, and can be the source of unscheduled downtime or dangerous situations. Therefore, it is important to find the root cause of vibrations by measuring and analysing the vibration signals. Common causes of vibrations are discussed below.

re vibration vertical roller mill. There are a number of reasons for high vibrations in vertical roller mills, such as: 1. Failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete.

The model of coal mill induced draft fan of a company is W4-73-15NO19F, the air volume is 100000m³/h, the wind pressure is 2200Pa, the rated current is 28A, the design speed is 960r/min, the motor power is 250kW, and the actual operating current is 19 ~ 20A. The fan is generally stable at the beginning of operation, and the vibration of the fan bearing house is …

Vibration is simply a back and forth movement—or oscillation—of machines and components in motorized equipment. Vibration in industrial equipment can be a symptom, or cause, of a problem, or it can be associated with normal operation. For example, oscillating sanders and vibratory tumblers rely on vibration to function.
