Grinding Media Cast Cylpebs for Cement Plant
1. Product scope
• Specifications: Φ 8 × 8 mm - Φ 50 × 60 mm (length can be adjusted as needed)
• Chromium content: 1% -28% (available in low chromium, medium chromium, and high chromium series)
• Hardness: HRC 40-66, can be oil quenched or air quenched heat treated
• Impact value: ≥ 1.5 J/cm ², crushing rate<0.5%, ensuring no breakage inside the mill
2. Performance advantages
High hardness and wear resistance, reducing the amount of replenishment and downtime
Combining the grinding characteristics of steel balls and steel bars, it is not easy to over grind and improves the qualification rate of cement specific surface area
Good toughness, no breakage or loss of roundness during transportation and use
3. Applicable scenarios
Cement plant ball mill first and second compartments, or pre grinding system
• Also applicable to power plant coal mills, beneficiation plants, chemical and building materials industries
4. Packaging and delivery
• Packaging:
- Flexible container bag 1000 kg/bag
Iron drum 850-900 kg/drum
- Can be reinforced with pallets or wooden boxes according to customer requirements
Delivery time: 5-10 days for spot goods, 15-20 days for production scheduling; Regular minimum order quantity of 20 tons
