Modern grinding/fluting machines play a critical role in aggregate processing lines, particularly in shaping high-quality sand and gravel for construction applications. These precision machines combine grinding rollers with advanced fluting technology to achieve optimal particle size distribution.
| Model | Max Feed Size (mm) | Output Capacity (t/h) | Motor Power (kW) |
|---|---|---|---|
| GFM-1000 | 50 | 80-120 | 110 |
| GFM-1500 | 80 | 150-200 | 160 |
| GFM-2000 | 120 | 250-350 | 220 |
The complete production line typically includes:
1. Primary jaw crusher for initial size reduction
2. Secondary cone crusher/intermediate crushing
3. Grinding/fluting machine for final shaping
4. High-frequency screening system
5. Automated grading and washing units
Q: How often should grinding rollers be replaced?
A: Typically every 800-1,200 operating hours depending on material hardness.

Q: What’s the ideal moisture content for feeding material?
A: Below 5% moisture ensures optimal grinding efficiency.
Q: Can the system process recycled concrete?
A: Yes, but requires pre-screening to remove rebar contaminants.

A Malaysian operator achieved 280tph output using GFM-1500 units configured with:
– Dual-stage pre-crushing
– Closed-circuit grinding system
– Automated moisture control
Final product met EN 12620 standards for concrete aggregates with <3% flakiness index.
