Compared with the traditional "blasting flame cutting" mining, granite mining with rope saw has the following advantages:
1, wide adaptability, rope saw is suitable for all types of mines, and flame cutting is only suitable for quartz content, less crack granite mine.
2, strong function, high efficiency, the first mining depth, can reach 0-20mm, or even deeper, flame cutting is generally only within 10m; Secondly, the cutting speed is fast, generally can reach 3-4m2 /, is 2-3 times the flame cutting.
3, rope saw can be vertical, horizontal, inclined plane and other directions of cutting, but also blind cutting, and flame cutting can only be vertical cutting.
4, high yield, low comprehensive cost, first of all, the cut surface of the wire saw is very smooth And waste material will not cause any internal injuries, secondly kerf is small, only about 11 mm, not cause waste of resources, and flame cutting edge rough, and cause a certain internal injuries to waste material, and kerf, general is 100-300 - mm, caused great waste of resources, And mining is expensive
Mining 5, security, environmental protection, wire saw no noise and no dust does not affect nearby residents and other operation, and high degree of automation, separate control, workers and old low strength, high safety, and flame cutting noise and dust is very big, serious impact on nearby residents and other workers, and workers labor intensity is big, the security is relatively low, to sum up, in the increasingly scarce resources, With the oil price soaring today, mining granite with rope saw has significant economic and social benefits.
The various factors associated with the diamond rope saw include the cutting life of the beads, the cutting speed of the beads, the spacing of the beads on the rope saw, the mold design, the life of the steel rope under normal working conditions and other technical difficulties.
The most common questions:
1, rope and use the most frequently encountered not cutting is not correct to choose diamond (diamond) often choose very good, the tire body and the distance between beads, mould design or error parameters, for example, we choose high diamond density or too good, its cutting performance is not very good, the diamond will not easily broken, which is difficult to produce a new force of the blade.
2, saw fracture saw wire rope fracture, usually is to use the wrong application parameters or rope saw the poor quality, which means that the plastic/rubber and combination between diamond beads not firm, lead to debris into diamond saw rope, quickly magma or cuttings in beaded steel body with steel rope part contact and friction between steel rope, steel rope connecting thread began to break, It could also be due to the wrong application of a binding agent. The fracture of the steel rope may also be caused by the wrong selection of wire rope, beaded steel body, and poor heat treatment after injection molding.
3, if the beaded cutting layer part of the beaded steel spalling off, it is usually the improper selection of fetal body, or the use of the wrong sintering parameters. Often incorrect cold pressing processes are also to blame for spalling. Sometimes due to improper dewaxing process, the metal tire and beaded steel body between the infiltration of paraffin. Sometimes the problem is also related to improper cleaning of beaded steel bodies.
4, the beads are loose and the beads are not firmly combined, which is usually a signal of problems when injection molding. It may also be improper selection of wire rope, or diamond beads internal contamination, improper cleaning, which will lead to beads and injection/injection rubber combination is not strong.
