    9/28/2019· Obtained results indicate that grinding pressure, primary air (PA) temperature and mill motor current have a tendency to rise by increasing coal feeding mass flow rates for all used coal.

  • DETECTING CLASSIFIER-COAL MILL DAMAGE USING A SIGNAL

    178 D. Romahadi et al., Classifier-Coal Mill Damage Detection using Vibration Signals Analysis ISO 10816 provides criteria to assess the vibration levels when measurements are made directly at the measurement site. The specified criteria apply to the machine devices the power of which is over 15 kW and the operating speeds of

  • Vibration monitoring for planetary gearbox in vertical

    Description. Vibration monitoring is one of the most important methods to detect and diagnose faults in gearboxes. Planetary gearbox in vertical axis coal mill experienced high impact load and severe working condition that increase wear and shorten usage life. Existing vibration monitoring system based on overall vibration levels repeatedly causes

    1/21/2011· Now, when the mill is started, vibration values are around 14 mm/s, first 4 harmonics of the GM, and then for about half an hour they go up to 28 mm/s (again 4 harmonics of GM) in horizontal direction while in the vertical and axial direction there is no such change.

  • vibration vertical roller mill Page 1 of 2

    3/1/2016· 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.

  • coal hardgrove index and mill vibration

    A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.
