Industrial chemical reactors and metallurgical furnaces require strict particle size control to maintain safe, predictable reaction rates. A size that is too small can cause sudden gas spikes, while a size too large can slow down your production.
As a direct-furnace manufacturer, we offer all sizes of calcium carbide, strictly screened through multi-layer precision vibrating sieves. From ultra-fine granules for laboratory chemical syntheses to massive lumps for steel mill desulfurization, we have your exact mesh size in stock.
We divide our annual 70,000-ton capacity into specific fractions to match every industrial application:
| Size Range (Mesh) | Primary Industrial Application | Recommended Packaging |
| 1-4 mm & 4-7 mm | Fine chemical reactions, calcium cyanamide production | 50kg Steel Drums |
| 7-15 mm & 15-25 mm | Medium-scale acetylene generators, localized welding gas | 50kg Steel Drums |
| 25-50 mm | Standard industrial acetylene gas stations (Global Best Seller) | 50kg / 100kg Drums |
| 50-80 mm & 80-120 mm | Heavy steelmaking deoxidation & ladle furnace (LF) desulfurization | 100kg Bulk Drums |
Can't decide on a single size? We support mixed-size container loading. You can combine multiple particle sizes (e.g., 60% of 25-50mm and 40% of 80-120mm) within one single 20ft container to satisfy different production lines at your plant.
No matter which particle size your process demands, we guarantee identical premium chemical properties across all fractions:
Guaranteed Gas Yield: $\ge$ 295 L/kg (Acetylene gas output)
Moisture Protection: Every size is packed in heavy-duty tinplate drums (50kg or 100kg) and fully flushed with pure nitrogen gas before mechanical sealing to prevent degradation.
Impurity Limits: Strict laboratory control over Phosphine ($PH_3 \le 0.08\%$) and Hydrogen Sulfide ($H_2S \le 0.10\%$).
Stop wasting time coordinating with multiple suppliers for different specifications. Get all sizes of calcium carbide from one certified, compliant Chinese factory with 15 years of dangerous goods export experience.
