clinker grinding process in cement taiwan

The clinker grinding process in cement production in Taiwan involves several key steps to transform clinker (produced from kilns) into fine cement powder. Here’s an overview of the process:

1. Clinker Preparation
– After cooling, clinker nodules (from the kiln) are stored in silos before grinding.
– Additives like gypsum (CaSO₄·2H₂O) and supplementary materials (e.g., limestone, slag, fly ash) are blended to regulate setting time and enhance properties.

2. Grinding Process
The clinker is ground in a ball mill, vertical roller mill (VRM), or roller press + ball mill hybrid system:
– Ball Mill: Traditional method where steel balls crush clinker into powder.
– Vertical Roller Mill (VRM): More energy-efficient, using rollers to grind clinker against a rotating table.
– Hybrid Systems: Some Taiwanese plantse a combination of roller press and ball mill for higher efficiency.

3. Particle Size Control
– Ground cement is passed through a separator/classifier to ensure proper fineness (Blaine fineness ~3000–4000 cm²/g).
– Oversized particles are recycled back for regrinding.

4. Storage & Packaging
– Finished cement is stored in silos before bulk transport or bagging.
– Taiwan’s cement industry follows strict quality control to meet local/international standards (CNS, ASTM, EN).

Key Features in Taiwan’s Cement Industry
✔ Advanced grinding technology (e.g., VRMs for energy savings).
✔ Use of industrial byproducts (slag, fly ash) for eco-friendly cement.
✔ Compliance with environmental regulations (dust control, low NOx emissions).
