The resonance of the trommel machine refers to the fact that the vibration frequency of the entire equipment is consistent during the screening process due to inertia, which increases the vibration amplitude of other components, thereby exceeding the vibration frequency during operation, then how to prevent resonance? We will introduce the following methods to you:
The shock-absorbing spring of the trommel screen separator can be replaced with a composite spring. The composite spring has high-strength damping, which can effectively limit the resonance area, slow down the resonance time, and reduce the effect of the vibration frequency of the entire screening equipment.
The vibration frequency of the trommel machine can be changed to be inconsistent with its own inherent vibration frequency, and the vibration frequency of the trommel machine can be changed through the vibration motor to prevent resonance.
The included angle of the eccentric blocks at both ends of the motor can be adjusted to change the magnitude of the exciting force. The smaller the included angle, the larger the exciting force and the larger the amplitude; on the contrary, the larger the included angle, the smaller the exciting force and the smaller the amplitude.
When the trommel machine is stopped, because the inertia will have the same vibration frequency as the trommel machine itself for a certain period of time, resonance will occur. A braking system can be installed on the trommel machine, and reverse current can be added to the vibration motor when it is stopped, which forces the motor to stop running quickly, so that the vibration frequency skips the natural vibration frequency of the screen machine itself, so as to achieve the purpose of preventing resonance.
The vibration motor of the trommel machine needs to be installed on a heavy chassis, which can increase the natural frequency of the trommel machine itself to increase the vibration frequency gap with the vibration motor to prevent resonance.
During the use of the trommel machine, it is necessary to feed at a constant speed so that the equipment cannot be overloaded for screening. The interior of the trommel machine also needs to be cleaned frequently to prevent the accumulation of residual materials. If the trommel machine is overloaded, it will also affect the vibration frequency of the trommel machine, resulting in the occurrence of resonance.
