In general, the main noise source of concrete batching plant has three aspects: the host's mixing of concrete batching plant, the dosing system and the pneumatic system. Here are several common methods for noise reduction in concrete batching plant.
- Reduce the host noise of the concrete batching plant. The common way is choosing foam sandwich panels with good sound insulation to package the host of concrete batching plant.
- Reduce the noise of batching system. Due to the large area of the batching machine, to insulate sound by sandwich panel and hollow brick can achieve a good effect.
- Reduce the noise of the pneumatic system. Most concrete batching plants use cylinders as the implementation components, resulting in a large impact and big noise at the end of the stroke. To buffer cylinders by introducing gas-liquid contact can help to reduce the noise.
