How to Reduce Resonance Damage of Grinding Mill

There maybe resonance in Vertical Mill operation. When the machine is operating under certain driving force, resonance will largely increase the vibration and may cause damage. The rotation speed causing resonance is called 'danger rotation speed'. This could be danger in grinding mill operating.

To reduce parts resonance, manufacturers must try to increase the value of 'danger rotation speed'. For this, Guilin Hongcheng applied various of technologies on Vertical mills.

1.Long parts are designed into two parts. For example, the driving axis is divided into two parts and connected by bearing. The structure reduced the length of driving axis, reducing the damage of resonance.

2. The high pressure oil pipe of of motor is very long. When the motor is operating, the large vibration may cause damage to the joint of oil pipe. For this, we apply high performance and high quality material to cast the pipe, and our pipe designing can obviously reduce vibration.

3. When the equipment operating under bad situation, the rotation speed of the equipment should be adjusted to reduce. If the equipment has too serious vibration, a reasonable rotation speed can protect the mill and other parts.
