Flame Cutting is a way to cutting rocks with high efficiency and the character of easily operating. It is driven by the diesel oil as the fuel, air compressor as the supporter of combustion. In virtue of spraying, heating up, and burning, then forming high temperature through the spear mouth, and it will eject large flame to rocks, which make the thermal energy spread on the surface of the rock and break it rapidly, then forming stone pieces which will be blown by little wind layer by ayer, demolishing gradually,
and forming stone trench at last, it can enhance the mining speed several times comparing to the manual in the past, and features fast speed, high effectiveness, non-demolishing the former texture, it is widely used to mine the granite stone.
