Speckle noise reduction in the laser mini

The contrast of speckle can be reduced to 2.32 which is invisible to human eyes when the diffuser is vibrated at 100Hz. Considering the trade-off between optical efficiency and speckle noise, the optimal arrangement of circular diffuser is 30h, 55h. The vibration direction is on the long side of the light...

How to reduce vibrating screen noise

Therefore, we carried out the analysis of vibration screen noise source and noise reduction measures. Firstly, after analyzing the main noise sources, such as sieve plate, side plate, exciter bearing and steel spring, the following noise reduction measures are put forward.

Introduction to the method of reducing noise by

3. Vibrating screen is composed of vibrating motor, bottom frame, screen and related accessories. There will be some noise in the production and operation, especially when the vibration screen is abnormal, the noise will be greater, which will bring great problems to the production environment. At the same time, it also affects the quality of the vibrating screen.

How to reduce vibrating screen noise and dust

Therefore, damping materials can be applied to the surface to achieve the purpose of noise reduction. The vibrating screen has a feeding trough and a discharging trough. The chute is welded from steel plates. The impact and friction of materials in the chute will also affect the noise of vibrating screen.
