Comparison of ancient marble quarrying and trade and Kanghua diamond wire saw mining methods

With the localization of diamond wire saws. The market competition for diamond wire saws suddenly became fierce. The emergence of this phenomenon indicates that the era of the use of diamond wire saws in China's stone mines has arrived, which will bring revolutionary progress to the improvement of China's stone mining.

Advantages of applying wire saws for stone mining Compared with traditional “blasting flame cutting” mining methods, the use of wire saws for mining granite has the following advantages:

1. Wide adaptability, wire saw is suitable for all types of mines, and flame cutting is only suitable for granite mines with high quartz content and few cracks.

2, strong function, high efficiency, first deep mining depth, can reach l0 ~ 20m or even deeper, flame cutting is generally only within 10m; second cutting speed is fast, generally can reach 3 ~ 4m2 / h, is flame cut 2 ~ 3 Times.

3. The wire saw can cut vertically, horizontally, and beveled in all directions, and can also perform blind cutting, while flame cutting can only perform vertical cutting.

4. High finished product rate and low comprehensive cost. Firstly, the cutting surface of the wire saw is very flat and does not cause any internal damage to the blocks. Secondly, the kerf is small, only about 11mm, which will not cause waste of resources; and the flame cutting surface is rough and uneven. It causes certain internal injuries to the blocks, and the kerf is large, generally 100 to 300 mm, resulting in a large waste of resources and high mining costs.

5, safety and environmental protection, wire saw mining without noise and dust, does not affect nearby residents and other work surfaces, and high degree of automation, separate control, low labor intensity and high safety; and flame cutting noise and dust are very large, It seriously affects the operations of nearby residents and other workers, and the workers are labor intensive and relatively low in safety. In summary, in today's increasingly scarce resources and soaring oil prices, the use of wire saws for the mining of granite has significant economic and social benefits.

Various factors associated with diamond wire saws include: sawing life of beading, sawing speed of beading, spacing of beading on wire saw, mold design, life of steel rope under normal working conditions, and other technical difficulties.
