IP PA for a mining processing plant with ball mills, concentrators, and tailing area?

Industry: factory | Architecture: IP

Mineral processing plants are among the noisiest industrial environments — ball mills and crushers regularly exceed 100dB, making conventional PA speaker placement strategies inadequate. The BNA 9000-i125-HA IP server manages all processing zones over the plant LAN. BNA IP-H15-POE horn speakers in ball mill areas are installed at short intervals (8-10m) inside the mill building, angled downward toward personnel walkways for near-field sound projection — this achieves 10dB above background (intelligible) at lower output levels than fewer high-powered speakers. BNA 9200 IP field call stations at the ball mill control cabin, flotation supervisor station, and tailing disposal pump station allow rapid emergency calling to the control room. BNA 9100 SIP master station at the plant manager's office handles all-zone safety broadcasts during equipment failures or tailing emergency scenarios.
