  • High vibrations on a ball mill AMP Maintenance Forums

    21.01.2011· Hello everyone, I have a problem with high levels of vibration at the supports of the pinion (fixed and floating bearings) of the cement ball mill. The kinemantic scheme with the measurement locations and several representative spectra and timewaves are in the attched file. The dominant vibrations are in the horizontal direction of measurement while at the same time I noticed also high levels of axial vibration

  • Vibration Ball Mill New Design Double Tubes Vibrating

    13.07.2020· Vibration ball mill, also known as a vibrating ball mill or vibratory ball mill, is a kind of ball mill machine that uses the high-frequency vibration of the cylinder to make the grinding medium in the cylinder impact the material by inertial force. Vibration ball mill is a new type of high-efficiency and energy-saving grinding equipment.

  • Vibration Due To Shaft Misalignment Manufacturing.net

    Too long or too short coupling spacers may cause high 3× which may be confused with misalignment. The author’s experience has shown this problem to produce a high 1× vibration also. A bent shaft produces high axial vibration. Phase shift will be 180 degrees when comparing top to bottom of bearing and 180 degrees from one side of bearing to the other.

    Ball Mill Vibration Troubleshooting. High vibrations on a ball mill AMP Maintenance Forums Jan 20 2011 · Now when the mill is started vibration values are around 14 mms first 4 harmonics of the GM and then for about half an hour they go up to 28 mms again 4 harmonics of GM in horizontal direction while in the vertical and axial direction there is no such change

  • Misalignment Axial Vibration Symptoms Due to Shaft

    Most practical vibration "wisdom" indicates that high axial vibration indicates coupling misalignment. Some use the rule that when the axial vibration reaches at least 50 percent of the radial vibration (horizontal or vertical), the source for the vibration is coupling misalignment. This rule is a reasonably good one but, unfortunately, is not always reliable. Coupling misalignment doesn't always create high

  • Sag Mill Syncronis Motor high axial vibration non drive

    The vibration frequency 2400CPM is dominate all over the drive train. With the high vibration the axial motor non drive end is the highest followed by the pinion non drive end. You could say the shaft has like a tuning fork effect. I had a look at information on the exciter and it has 6 diodes and was just looking for a clue. Now we have found out this is not the original exciter and one was retrofitted 4 years ago but

  • axial vibration of ball mill pinion

    We are experiencing high vibration on our dual drive ball mill. The high vibration is on the motor DE bearing on axial direction. Dominant frequency is girth and pinion gear mesh. See attached spectrums and trends. Gearbox holddown bolts are breaking due to high vibration. Keeping those ball mills turning Australian Mining. Ask for quote. The pinion is a small gear with a matching tooth

  • High vibration on the ball mill drive train A and B AMP

    Visually check the pinion teeth. More likely the source is a failure on the pinion support bearings or housing looseness. Therefore gear mesh is not working in the proper way. Due to described breaking bolts, the entire machine should be realigned. The machine obviously needs the immediate repair.

  • How to Reduce the Vibration During the Milling Process

    In addition, the 10°milling cutter transmits the main cutting force to the spindle, thereby reducing vibration caused by long tool overhang. Choose the smallest possible diameter for the process. DC should be 20-50% greater than ae.

  • Misalignment Axial Vibration Symptoms Due to Shaft

    Precaution: When axial vibration is high, first check to see if there are symptoms for other sources for higher than usual axial vibration, such as: 1. Resonance of some part in the axial direction, such as a pedestal or pipe. When diaphragm (flexible disc-type) couplings are used, the disc or discs may be resonant in the axial direction. 2. The couple component of dynamic unbalance. 3. Bent
