1. Wide adaptability
Wire saws are suitable for various mines, while flame cutting is only suitable for granite mines with high quartz content and few cracks.
2. Powerful function and high efficiency
First, the mining depth is deep, up to 10~20m or even deeper, and flame cutting is generally only within 10m; secondly, the cutting speed is fast, generally reaching 3~4m2/h, which is 2~3 times that of flame cutting.
3. Multi-directional cutting
Wire saws can cut vertically, horizontally, diagonally and blindly, while flame cutting can only cut vertically.
4. High output and low comprehensive cost
First of all, the cutting surface of the wire saw is very flat and will not cause any internal damage to the stone. Secondly, the sawing gap is very small, only about 11mm, which will not cause waste of resources;
The cutting surface of flame cutting is rough and uneven, causing certain internal damage to the stone, and the sawing gap is large, generally 100~300mm, resulting in waste of resources and high mining costs.
5. Safety and environmental protection
The diamond wire saw machine has no noise, no dust, and does not affect the nearby residents. It has a high degree of automation, independent control, low labor intensity and high safety;
The noise and dust of flame cutting are very large, which seriously affects the operations of nearby residents and other workers. Workers have high labor intensity and relatively low safety.
To sum up, in today's increasingly scarce resources and soaring oil prices, mining granite with diamond wire saw machines has significant economic and social benefits.
