Diamond wire saw for quartzine feedback is good from Brazil:
| Date | Length of wire | Times | Stone name | Machine No. | Manufacturer | Power KW | Block: L/H | Life: m2 | Efficiency: m2/h | Electronic current A | Line speed: m/s | Beads diameter |
| 2021/12/10 | 50 | 12.9 | QUARTZITE PLATINUS | MF21 | SKYSTONE | 75 | 10,50 X 13,00 | 136.50 | 10.58 | 145 | 30 | 11.70 |
| 2021/12/16 | 50 | 6.87 | QUARTZITE PLATINUS | MF21 | SKYSTONE | 75 | 13,00 X 7,00 | 91.00 | 13.25 | 140 | 30 | 11.20 |
| 2022/1/17 | 50 | 5.9 | QUARTZITE PLATINUS | MF21 | SKYSTONE | 75 | 10,20 X 7,20 | 73.44 | 12.45 | 134 | 32 | 10.20 |
The life is about 300m2 and the beads still 10.2mm, and speed is about 12m2/h. Sounds good, so the life expect to be 500-600m2/ for 50m.
