  • The Measures to control the Noise during the Grinding

    Many ball mill plants produce a lot of noise in the grinding process of bal mill. So, how to control these noise? The most direct, effective, and economic measure is to reduce the sound resource. Based on the years of experience, Luoyang Dahua summarizes as below: 1. Ball mill will generates larger vibration during working process, so the

    A Study in Ball-Mill Noise Control Abstract: Ball-mill noise became a matter of general concern with passage of the Walsh-Healy Act in 1969. This act is now a part of the broader safety act known as the Occupational Safety and Health Administration. Noise is one of the ``newest pollutants'' in terms of the definition set forth in the Walsh-Healy Act. Studies are currently underway to establish
