The traditional blasting approach of mine exploitation no longer handiest causes extreme environmental damage however additionally ends in resource waste. Currently, the maximum widely promoted technique of mine exploitation is using diamond twine saws for mine extraction.



With the localization of diamond twine saws, the market competition for diamond wire saw machines has unexpectedly become severe. The emergence of this phenomenon indicates or represents that the generation of huge use of diamond twine saw machines in China's stone mines has arrived. This will bring revolutionary development to the improvement of the stone mine exploitation stage in China.


The blessings of using twine saws for stone mine exploitation, as compared with the conventional "blasting and flame slicing" exploitation method, using twine saws to mine granite has the following benefits:

Wide adaptability: Wire saws are appropriate for all varieties of mines, whilst flame slicing is handiest applicable to granite mines with high quartz content material and few fractures.

Strong functionality and excessive efficiency: Firstly, the mining depth is deep, which could attain 10 to 20 meters or maybe deeper, even as the flame reducing intensity is commonly inside 10 meters. Secondly, the slicing velocity is rapid, generally attaining 3 to 4 square meters in step with hour, that's 2 to a few instances that of flame reducing.


The wire noticed can perform reducing in all guidelines, along with vertical, horizontal, and inclined surfaces, and can also perform blind slicing. In assessment, flame reducing can only be executed on vertical surfaces.

High yield price and coffee comprehensive fee: Firstly, the slicing floor of the wire noticed is very easy and will now not purpose any inner harm to the block. Secondly, the noticed kerf is small, simplest approximately 11mm, and will now not reason aid waste. However, the slicing floor of flame reducing is tough, and it will reason sure inner damage to the block. Moreover, the saw kerf is big, commonly a hundred to 300mm, resulting in a splendid deal of aid waste and high mining charges.


Safe and environmentally friendly: Mining with wire saws produces no noise or dirt, does no longer affect close by citizens and other operating surfaces, and has a excessive diploma of automation. It may be operated in a separated manner, with low hard work depth and high protection for workers. In assessment, flame slicing generates a huge amount of noise and dust, critically affecting close by residents and other workers' operations, with excessive hard work depth for employees and comparatively low safety. In conclusion, in contemporary context of increasingly more scarce assets and soaring oil costs, using cord saws to mine granite has great monetary and social blessings.

There are different factors associated with diamond twine saws, along with the cutting life of the beads, the cutting speed of the beads, the spacing of the beads on the cord saw, mold design, the life of the metal cord underneath ordinary working situations, and other technical difficulties.


The maximum not unusual issues:

Inability to cut with the wire noticed: The maximum not unusual issues encountered in the use of cord saws are the incorrect choice of diamonds (regularly deciding on diamonds which can be too top), the matrix, bead spacing, mould layout, or wrong application parameters. For instance, if we pick out a diamond density that is too excessive or diamonds which might be too excellent, the cutting overall performance will now not be highest quality. The diamonds will now not be easy to break, making it tough to generate new sharp reducing edges.


Wire noticed breakage: The breakage of the wire noticed is normally due to using incorrect application parameters or negative first-rate of the cord noticed. This way that the bonding between the plastic/rubber and the diamond beads isn't always organization, permitting rock particles to go into the diamond wire saw. Soon, the magma or rock particles will partially touch and rub in opposition to the metal twine between the bead metallic body and the metallic cord, and the relationship threads of the steel cord will start to interrupt. This may also be due to the incorrect use of the binder. The breakage of the steel twine can also be because of the incorrect choice of the metallic twine, the bead steel body, or bad warmth treatment after injection molding.

Bead peeling: If the cutting layer a part of the bead peels off from the bead steel frame, it is also because of the improper selection of the matrix or the use of wrong sintering parameters. The use of an incorrect cold pressing system is often also a motive of peeling. Sometimes, it is able to be due to wrong dewaxing, which allows paraffin to seep between the metallic matrix and the bead metal frame. Sometimes, this hassle is likewise related to improper cleansing of the bead metallic frame.


Weak bead bonding: The looseness and vulnerable bonding of the beads are typically a signal of troubles throughout injection molding. It may also be related to the unsuitable choice of the metal wire, or inner infection of the diamond beads and flawed cleansing, with the intention to cause vulnerable bonding between the beads and the injection-molded plastic/rubber.
