10-inch x 20-inch jaw crusher is usually equivalent to the Chinese standard model PE-250×400 jaw crusher (feed opening size 250mm×400mm). The following is a detailed comparison and key parameter description:
1. Size and model comparison
• Imperial specifications: 10 inches × 20 inches (254mm×508mm)
• Metric model: PE-250×400 (actual feed opening 250mm×400mm, close to the imperial size, may vary slightly due to brand).
Note: Some manufacturers mark it as "250×400", and the actual feed opening is slightly larger than the nominal value (such as 255×400mm).
2. Main technical parameters
| Parameters | PE-250×400 (10×20 inches) |
| Feed port size | 250mm×400mm (≈10×16 inches, the actual effective width may be slightly smaller) |
| Maximum feed particle size | ≤210mm (long side direction) |
| Discharge port adjustment range | 20-80mm (common adjustment range 40-60mm) |
| Processing capacity | 5-20 tons/hour (depending on the material and discharge port) |
| Motor power | 15- 30 kW (about 20-40 horsepower) |
| Equipment weight |
3. Application scenarios
• Applicable materials: medium and low hardness ores or construction waste such as limestone, bluestone, and coal gangue.
• Typical uses: small mines, quarries, laboratory crushing, and concrete recycling.
4. Differences from Imperial specifications
• Actual feed opening: The feed opening of some domestic PE-250×400 is actually 255×400mm (slightly larger than 10×16 inches), while the Imperial 10×20 inches (254×508mm) may correspond to a larger model (such as PE-250×500).
5. Maintenance and accessories
• Consumable parts: jaw plate (Mn13Cr2), side guard plate, toggle plate.
• Maintenance cycle: Check bolt tightness every 8 hours and replace bearing grease every 500 hours.
If precise selection is required, it is recommended to provide the following information:
• Material hardness (such as compressive strength MPa);
• Target discharge particle size (such as 30-50mm);
• Hourly production demand (such as 15 tons/hour).
