Grinding wheel rock technology is essential for processing concrete rubble into high-quality sand and aggregates. This process typically integrates into a complete crushing-screening-grinding production line, delivering precise particle sizing for construction applications.
1. Primary Jaw Crusher: Reduces large concrete chunks to 150-300mm
– Model example: JC5460 (500TPH capacity, 250kW motor)
2. Impact Crusher (Secondary): Further crushes material to ≤50mm
– Features hydraulic adjustment and rock-on-rock crushing
3. Grinding Wheel System: Specialized abrasive wheels for final shaping
– Diamond/CBN composite wheels (600-1200 grit available)
– RPM range: 800-1500 with water cooling
| Equipment | Capacity (TPH) | Power (kW) | Output Size (mm) |
|---|---|---|---|
| Jaw Crusher | 200-600 | 160-315 | 50-300 |
| Cone Crusher | 100-400 | 90-250 | 10-50 |
| Grinding Wheel Station | 30-100 | 75-150 | 0.1-5.0 |

Q: How often do grinding wheels need replacement?
A: Typically 500-800 operating hours depending on concrete hardness.

Q: Can the system process reinforced concrete?
A: Yes, but requires magnetic separators for rebar removal first.
Q: What’s the typical energy consumption?
A: About 3.5-4.5kWh per ton of finished product.
