As a result external vibration effect is less outside the mill. As per the sensor selection is concerned for a heavily loaded ball mill, the sensitivity of the sensors should be high as compared to the ‘g’ value required, and the BW of operation can be limited by the mass of the balls present on the surface of the mill during grinding.

When the grinding pressure is lower than the set pressure, it should be filled with nitrogen immediately to increase the grinding pressure. The balance between the three stretching rods should be ensured during the operation of the equipment. The imbalance between the stretching rods will increase the vibration of the equipment.

In a roller mill, bearings allow the rollers to rotate at high speeds and support the grinding load. A faulty bearing can cause serious operational issues, such as excessive vibration, noise, and wear. Therefore, bearing monitoring is critical to prevent unplanned downtime, reduce maintenance costs, and increase equipment efficiency.
