P&ID extraction for cement.
A cement plant runs as one continuous machine. Raw material, pyroprocessing, finish grinding, dispatch. A drawing set typically spans 80-150 pages with dense cross-unit signal flow and safety-critical interlocks on kiln, coal mill, and clinker cooler.
- I/O list segmented by raw mill, kiln, coal mill, clinker cooler, finish mill
- Instrument index covering the harsh-service measurements, temperature, pressure, flow on dust streams
- Equipment list with kiln, mill, and cooler metadata
- SIS subset for combustion and dust-collector protection
- Kiln controls combine BPCS feed-rate and combustion loops with SIS overtemperature, overpressure, and oxygen monitoring
- Coal mill explosion protection, CO and O2 monitoring, inerting carries SIS scope. SIS-prefixed tags preserved
- Baghouse and ESP dust collector controls carry environmental compliance scope. Extracted dataset supports audit responses
- Alternative fuel firing, RDF, tires, biomass adds feed-system instrumentation and emissions monitoring. I/O list grows 50-150 tags per campaign
- Vertical roller mill and ball mill drawings carry vibration and bearing-temperature instrumentation typical of rotating equipment in heavy industry
- Quarry and raw materials handling run as a separate workspace. Conveyor and stacker tag conventions differ from pyroprocess
- CCR, HMI architecture varies by plant. Drawing-side tagging is consistent across FLSmidth, ThyssenKrupp, KHD, and Sinoma supplier lineages
- NFPA 85 for solid fuel combustion controls
- MSHA for the quarry and raw materials handling scope
- Local air quality regulators, EPA, ECCC equivalents audit dust collector instrumentation
