Limestone grinding production line complete equipment
One-stop solution from coarse crushing to 325 mesh fine powder processing
1. Industry pain points: key challenges in limestone powder processing
Limestone (calcium carbonate) is widely used in building materials, chemical industry, metallurgy and other fields, but traditional processing methods often face:
✘ Low coarse crushing efficiency: Improper selection of jaw crusher leads to mismatched production capacity
✘ Substandard fineness: Ordinary Raymond mill is difficult to produce fine powder above 325 mesh (45μm) stably
✘ High dust pollution: Open design does not meet environmental protection requirements
✘ High energy consumption cost: Unreasonable equipment combination leads to electricity bills accounting for more than 30%
Solution: Modular design production line, covering the entire process of coarse crushing → medium crushing → grinding → grading → packaging, precise control of fineness (80-325 mesh adjustable), and energy consumption reduced by 40%
2. Analysis of the core equipment of limestone grinding production line
① Coarse crushing stage: jaw crusher
Function: crush the raw ore (≤800mm) to ≤50mm
Recommended model: PE600×900(50-100 t/h)
Advantages: high manganese steel jaw plate is wear-resistant, hydraulic adjustment of discharge port
② Medium and fine crushing stage: impact crusher/cone crusher
Applicable scenarios:
Impact crusher (processing hardness ≤350MPa, good finished product particle shape)
Cone crusher (high hardness ore, more than 200 tons per hour)
③ Grinding core: Raymond mill/vertical mill
| Equipment type | Fineness range | Capacity (T/H) | Applicable scenarios |
| Raymond mill | 80-325 mesh | 1-20 | Small and medium scale, low investment |
| Vertical mil | 325-2500 mesh | 5-50 | Large project, high fineness |
3. Production line process (with flow chart)
Coarse crushing → 2. Screening (vibrating screen) → 3. Medium crushing → 4. Grinding (with analyzer) → 5. Powder collection (cyclone + bag dust collector) → 6. Packaging
