The vibration source of roll grinder mainly comes from the following aspects: (1) The main reason is that the grinding wheel drive motor is unbalanced and produces vibration. (2) The grinding wheel does not balance dynamically and statically and vibrates when it rotates. (3) The length or tightness of the V-belt drive is inconsistent, resulting ...
The purpose of this study is to reveal the mechanism of unstable vibration occurring in the grinding operation of roller mills and to show the design guidelines for reducing the vibration.

ROLL GRINDERS Iso LVI Lateral Vibration Isolation An Iso LVI Laterally Isolated Foundation is created by lining the perimeter walls of a foundation with Farrat Iso high performance perimeter isolation material. Different stiffness grades are required depending on depth of foundation assuming the block is to be cast as one single pour.
The vibration generated by the processing system during the grinding process directly affects the quality and productivity of the roll surface. If the vibration is not eliminated and suppressed in time during the semi-finishing and fine grinding …
roll and wheel speeds during grinding process VIBRATION DATA PLOTS Real-time feedback of the vibration levels being transcribed to roll For steel and aluminum mills, it is important to monitor the roll grinding process for quality control. The work rolls touch every surface of product that passes through a mill. Therefore, any
Vibration monitoring has now become a well accepted part of many planned maintenance regimes and relies on the well known characteristic vibration signatures which rolling bearings exhibit as the rolling surfaces degrade. However, in most situations bearing vibration cannot be measured directly and so the bearing vibration signature is modified ...

Roll Grinding Machine Vibration Analysis. The correct way to measure concentricity on a grinding machine is 180 from wheel back side, if the roll is supported on grinding seats.For example, if the grinding seat is out of round this form will be transferred to the roll shell by the grinding wheel.
Roll grinders are often required to offer over 97% availability in order to keep the rolling mill production lines in operation but in many cases they need to be installed in environments where there is significant risk of shock and vibration within ground affecting the machine's performance.
Vibration testing in itself is only as effective as the ability of the analyst to interpret the data. This can become very difficult in roll grinder work due to the relatively low levels of vibration compared to other types of equipment. Even problem machines sometimes fail to provide strong enough signals to identify suspect areas.
The vibration problem in the grinding machine can be modeled as a lumped spring-mass system as in Figure 2. The double time delays from both roll and grinder are also considered [10-12].The equations of

If a roll is not round, it will vary nip pressure in every rotation and cause vibration. This can cause roll cover barring or vibration further down the machine. In some cases it can cause MD caliper variation in the sheet.
The purpose of this study is to reveal the mechanism of unstable vibration occurring in the grinding operation of roller mills and to show the design guidelines for reducing the vibration. To study the basic cause of the unstable vibration, we first investigated the dynamic characteristics of the mill vibration in its stable state and its unstable state, using a small laboratory roller mill.
