Cement clinker is a semi-finished product obtained by mixing raw materials of limestone, clay and iron as raw materials in a suitable proportion, burning until fully or partially melted, and cooling. In the cement industry, the main chemical components of Portland cement clinker in common use are calcium oxide, silicon dioxide, and a small amount of aluminum oxide and iron oxide. The main mineral composition is tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminate. Portland cement clinker can be made into Portland cement after grinding together with proper amount of gypsum.
| CaO | SiO2 | Fe2O3 | Al2O3 |
|---|---|---|---|
| 62%-67% | 20%-24% | 2.5%-6.0% | 4%-7% |
| Fineness | 220-260㎡/kg(R0.08≤15%) |
|---|---|
| Model | Vertical mill |
The material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).
The crushed small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.
Through classification, the coarse powder will return to main mill to grind again.
The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
