Technology sharing on reducing noise pollution in the sand making process of roller sand making machines

As an efficient and energy-saving sand-making equipment, the roller sand-making machine has been widely used in construction, road and other industries.However, the problem of noise pollution generated in the sand making process is also becoming more and more prominent, which has caused adverse effects on the health of operators and the surrounding environment.This article will introduce in detail several technical measures to reduce noise pollution to roller sand making machines, with a view to providing reference for relevant practitioners.

Analysis of the source of noise of roller sand making machine

The noise of the roller sand making machine mainly comes from the following aspects：

Mechanical vibration: The mechanical vibration generated by the roller during high-speed rotation.
Material impact: The noise generated when the material is squeezed and hit between the rollers.
Motor operation: Electromagnetic noise and mechanical noise generated when the motor is running.

Technical measures to reduce noise pollution

1. Equipment maintenance

Regular maintenance of the roller sand making machine to ensure its normal operation is the basis for reducing noise.Specific measures include：

Check and replace worn parts: Severely worn parts can cause unbalanced operation of the equipment and increase noise.Therefore, it should be checked regularly and replaced in time.
Adjust the working state of the equipment: By adjusting the clearance, speed and other parameters of the rollers, the equipment is in the best working state and noise generation is reduced.

2. Sound isolation measures

Setting up a soundproof wall or soundproof cover around the roller sand making machine can effectively isolate the spread of noise.The specific measures are as follows：

Choose appropriate sound insulation materials: Sound insulation materials should have good sound absorption and sound insulation properties, such as sound-absorbing cotton, sound insulation panels, etc.
Reasonable design of sound insulation structure: The design of sound insulation wall or sound insulation cover should consider the transmission path of noise to ensure that the sound insulation effect is maximized.At the same time, sufficient air vents should be left to ensure that the equipment dissipates heat.

3. Reasonable layout and planning

Noise control factors should be considered when designing and arranging workplaces for roller sand making machines.Specific measures include：

Reasonable planning of equipment location: Arrange noisy equipment away from densely populated areas and sensitive areas to reduce the impact of noise on personnel and the surrounding environment.
Reasonable arrangement of working hours: Avoid noisy operations during sensitive hours to reduce interference with surrounding residents and the environment.
Optimize the process flow: by improving the process flow, the number and strength of the material's impact between the rollers are reduced, thereby reducing noise generation.

4. Application of noise reduction technology

In addition to the above measures, you can also consider the application of some advanced noise reduction technologies, such as：

Active noise reduction technology: By installing an active noise reduction system, sound waves that are opposite to the noise are generated to offset the noise.
Vibration control technology: Through the installation of vibration sensors and controllers, the vibration status of the equipment is monitored and adjusted in real time to reduce noise generation.

The problem of noise pollution generated by the roller sand making machine in the sand making process cannot be ignored.Through equipment maintenance, sound isolation measures, reasonable layout and planning, and the application of noise reduction technology, noise pollution can be effectively reduced, the working environment can be improved, and the health of operators and the surrounding environment can be protected.In the future, with the continuous progress and innovation of technology, I believe that more efficient and environmentally friendly noise reduction technologies will be applied to roller sand making machines to contribute to the sustainable development of the sand making industry.
