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.
What cement drawings carry.
- 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
What the extraction delivers.
- 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
Instrument tags on a cement drawing.
- TT-K-205Kiln burning-zone temperature transmitter, loop 205
- AT-CM-104Coal mill analyzer transmitter, CO or O2 monitoring
- PSHH-BH-301Bag house pressure switch high-high, SIS service

Regulatory context.
- 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

Common questions
How does Tagsight handle the analyzers that drive coal mill and kiln combustion control.
Analyzer tags extract with the second-letter function preserved. Engineering range and sampling details live in the datasheet. The P&ID carries the tag, location, and signal class.
Does the extraction surface the CCR, DCS, PLC architecture split common in cement.
The extraction reads the drawing-side tag and signal class. Whether a tag is routed to a central CCR-DCS or a local PLC is a configuration decision in the controls philosophy document, not the P&ID. The extracted dataset is platform-agnostic until export.
Can it handle alternative-fuel feed system drawings.
Yes. AFR, alternative fuel and raw material feed systems extract the same way as primary-fuel drawings. Emissions monitoring tags filter into the environmental compliance subset.
How does this work on plants supplied by different OEMs.
FLSmidth, KHD, ThyssenKrupp, and Sinoma cement lines have stylistic drawing differences but converge on ISA 5.1, or DIN 19227 for European supply. Where vendor-specific symbology diverges, you confirm it in the review canvas.
Does it cover the quarry and crushing scope.
Quarry, primary crusher, and stacker-reclaimer drawings run as a separate workspace. Conveyor and weighfeeder tag conventions differ from pyroprocess. The output documents are the same, I/O list, instrument index, equipment list.
