Introduction:
To ensure optimal operation of the AHWI forest mulcher, it is essential to maintain a balanced rotor. In this context, the Balanset-1A device was used to dynamically balance the rotor of the forest mulcher.

Balancing Process:

Initial Measurement: The initial vibration of the rotor was measured using the Balanset-1A. Vibration exceeded 100 mm/sec, making it impossible to spin the rotor to its operational speed.

Weight Placement: Weights with known mass were placed on both sides of the rotor, which enabled the Balanset-1A to measure the change in vibration resulting from the weights.

Balancing at Minimum Speed: Given the excessive initial vibration, the first balancing was done at minimal rotation speed. After this, the device calculated the mass of the weights and the angle at which they needed to be placed for optimal balance.

Balancing at Operational Speed: Once the initial balance was achieved, the rotor was spun at its working rotation speed, and the process was repeated for fine-tuning.

Advantages of Balancing:

Noise Reduction: A notable decrease in operational noise.
Longevity: Increased lifespan of the bearings.
Efficiency: Reduced fuel consumption.
Durability: Fewer breakdowns and enhanced machine durability.

Conclusion:
The dynamic balancing of the AHWI forest mulcher's rotor using the Balanset-1A proved to be a highly successful endeavor. The original vibration level was significantly above 100 mm/sec, hindering its ability to reach the operational rotation speed. However, through careful and meticulous balancing at both minimal and operational speeds, the vibration was reduced to between 0.5 and 1 mm/sec. The benefits extend not only to reduced noise and fuel consumption but also to the prolonged service life of the machine's components.
