In addition to the dust and waste water pollution, the noise pollution is another aspect of the stationary concrete mixer plant product pollution to the environment. If the concrete mixer plant is set near to the residential area, the noise pollution is more obvious. Installed far away from residential area is one way to reduce the effect of large noise, while anther way is effort by adjust on the stationary concrete mixer plant product itself.



After the cause of the noise in the concrete mixing plant has been found, so that these noise pollution can be solved:
1. The entire sand and gravel yard is sealed with a sandwich panel to allow the noise to be digested internally;
2. The small independent concrete house set up for the air pump, gas storage tank and other gas supply equipment, it is recommended to choose hollow brick + concrete method, the discharge cylinder uses hydraulic cylinder;
3. The batching machine and the belt conveyor are all packaged, and the dust removal and noise reduction device is installed at the transfer part;
4. The concrete mixer of the stationary concrete mixer plant uses a baffle for packaging;
5. The main concrete mixer brand adopts large brand with high precision, the gap between the tank liner and the stirring blade can reach 0.5mm or less, and can avoid squeaking when the gap is too large, the special boring machine is used to increase the parallelism of the two agitating shafts to improve the stability of the transmission system to reduce noise;
6. Reforming the unloading hopper of stationary concrete mixer plant product, selecting chute type discharge or adding wear-resistant plates with strong toughness in the discharge port.
