Grinding Balls For Mining Application( Please let me know your application, Jinan zhongwei will recommend the most high cost-effective type)
- Ball Mill
- Mining
- Cement Plant
- Power Plant
Competitive advantage:
1.Top high cost performance;
2.Save annual steel ball use qty;
3. Increase outlet derived from the best quality .
Performance comparation:
- Steel Balls for Ball mill can save usage 40-50% than low chrome casting ball(chrome percent: 5%), improve outlet 10% at least than low chrome casting ball.
- Steel Balls for Ball mill can save usage 20-25% than medium chrome casting ball(chrome percent: 5% ~ 10%), improve outlet 10% than medium chrome casting ball.
- Steel Balls for Ball mill can save usage 10% than high chrome casting ball(chrome percent: 5% ~ 10%), improve outlet 10% than high chrome casting ball.
