How to balance the crusher rotor？

September 03, 2024

‌

Dynamic balancing of the crusher rotor refers to adjusting the mass distribution of the rotor so that its axis of rotation coincides with one of the main inertia axes, thereby reducing vibration and noise and improving the performance and life of the equipment. ‌

The specific operating steps of the dynamic balancing of the crusher rotor are as follows:

‌ Inspection ‌: First, conduct a comprehensive inspection of the rotating parts of the crusher, including the main shaft, rotor, flywheel, etc., to check whether there is looseness, wear, deformation or other damage. ‌

‌ Accurate measurement ‌: Use professional dynamic balancing test instruments to accurately measure the rotating parts, including detecting the mass distribution and imbalance degree of the rotating parts.

‌ Determine the correction position ‌: Based on the measurement results, determine the imbalance position and weight distribution on the rotating parts, which will guide the specific operation of the correction.

‌ Correction ‌: Based on the measurement results, add or remove counterweights to the rotor to reduce the amount of imbalance. ‌

‌ Test ‌: After completing the correction, perform a balancing test to ensure that the rotor does not generate excessive unbalanced centrifugal force when rotating. ‌

When performing dynamic balancing of the crusher rotor, the following points should also be noted:

‌ Ensure the machining and assembly accuracy of the rotor parts, and ensure that the rotor geometry is simple and regular for easy machining.

‌ Improve the wear resistance of the hammer head, replace the worn hammer head in time, and ensure that the weight of the hammer head is consistent.

‌ Ensure the uniformity of feeding, and avoid rotor imbalance due to uneven feeding.

‌ Choose the appropriate balancing method, and choose static balancing or dynamic balancing according to the rotor geometry, working speed and relevant standards. ‌

Through the above steps and precautions, the balance of the scrap steel crusher rotor can be effectively maintained to ensure the stable and reliable operation of the machine.
