Pack entire plant to reduce the noise pollution of the concrete batching plant:
The whole plant is packed, that is, all the machines in the concrete batching plant are packed.Adopting the acoustic panels to pack the concrete mixer and using the hollow brick for the material hopper will be two efficient methods to reduce the noise pollution of the concrete batching plant.
Adopt the new type concrete mixer reduce the noise pollution of the concrete batching plant:
Most of the noise are caused by the concrete mixer,the new type concrete mixer can reduce the noise effectively.
1)Improve the production accuracy of the concrete mixer:Develop a perfect program to enhance the products accuracy of the concrete mixer.Make sure the distance of the silo liner and stirring blade is less than 0.5 mm,otherwise, if the distance is too big, it will make a loud continuous noise. Select special boring machine to enhance the parallelism of the two stirring shaft and then improve the smoothness of the driving system to reduce noise.
2)Develop new type reducer for the concrete mixer:Former reducer of the concrete mixer is noisy and low accuracy that can't meet the requirements for a concrete batching plant.In the new type reducer, it adopts the opinion in the auto industry and the spiral bevel gear driving system and nitriding treatment for the tooth shape surface, so that the reducer of the new type concrete mixer can work stably and cause low noise.
