Ceramic Ball Stone for Ball Mill: Key Equipment in Sand & Aggregate Production

Ceramic grinding balls are critical wear-resistant media in ball mills for crushing and grinding hard materials like quartz, granite, and basalt in sand/aggregate plants. With 92% Al₂O₃ content and Mohs hardness ≥8.5, they outperform steel balls in corrosion resistance and lifespan (3-5x longer).

Typical Sand/Aggregate Production Line Configuration

1. Primary Crushing: Jaw Crusher (Feed size ≤1200mm, Output 50-800TPH)
2. Secondary Crushing: Cone Crusher + Vibrating Screen (Closed-circuit)
3. Grinding: Ball Mill with Ceramic Balls (Φ1.5-4.5m, Power 75-450kW)
4. Sand Making: VSI Crusher (Throughput 60-650TPH)
5. Classification: Hydrocyclone + Dewatering Screen

Frequently Asked Questions

Q1: Why choose ceramic over steel balls?

A: Lower contamination, suitable for high-purity quartz processing; 30% energy saving due to reduced weight.

Q2: How to determine ball size?

A: Match feed size – typically 20-30mm for 0-5mm feed; 40-50mm for 10-20mm feed.
