Delta Cement's link, then the kiln's link

1. Delta Cement's link: Country where the plant is located = Egypt (EG) → Model my plant for CN 25232900 → Cement → Cement (grinding).
2. To-do “no production quantity”: 1250000Copy → ⤓ Fill from data → paste, then Match to plant → → Fill 5 flows → Save:

   CopyCement clinker, 900000
   Gypsum / SCMs, 350000
   Drying fuel, 120000, 0.0561
   Grid electricity, 60000, 0.387
   Cement, 1250000

3. Back on the portal home: Ask your supplier for this figure (clinker) → Company Sinai Clinker Works (test)Copy, Email kiln@sinai-clinker.exampleCopy, English → Send request; copy the new link.

   Cement clinker, 1000000

5. Delta Cement's plant page → Submit to my customer (the clinker figure is now linked in).

Grid factor 0.387 = the official Annex II value for Egypt. A mass-balance hint on the kiln (raw meal in ≫ clinker out) is expected: calcination releases CO₂.
