At the beginning of December, Hubei Fertilizer conducted noise tests on the newly completed steel ball mill noise control project. The results showed that the average noise value of steel ball mills with acoustic enclosures was reduced by 18 decibels, further improving the on-site working environment.
Noise can have an adverse effect on the human body, but it is neither economical nor possible to completely eliminate productive noise. Therefore, controlling the noise intensity within a certain range is one of the important measures to prevent noise damage. The environmental noise in the field of chemical fertilizers in Hubei was originally within the scope allowed by the Noise Standard for Industrial Enterprise Noise. To further reduce the harm caused by noise to workers, Hubei Chemical Fertilizer invests another RMB 2 million to comprehensively treat key noise sources, which is the power plant's 6 Taiwan Steel ball mill installed acoustic enclosures. Acoustic enclosures are treated with new types of sound insulation materials and anti-noise technology.
