There are currently about four options for mechanized granite mining when diamond wire saw machine is used as primary or secondary granite mining equipment. They are: the combination of diamond wire saw machine and hand-held rock drill hole drilling, combined with controlled blasting granite mining scheme; The combination of diamond wire saw machine and bench drill and row hole, combined with controlled blasting granite mining scheme; The scheme of cutting granite with diamond wire saw machine; The scheme of cutting granite with full saw combined with diamond wire saw machine and double saw blade stone cutter.
If the diamond wire saw machine is used for granite mining, the empirical data of 4.86㎡ needed to be cut by the diamond wire saw machine for cutting and shaping waste material per unit volume can also be referred to. Combined with the average efficiency of the diamond wire saw machine in cutting and shaping hard granite is 4㎡/h, the annual mining capacity of each diamond wire saw machine can be calculated. If the diamond wire saw machine works eight hours a day and ten months a year, The auxiliary time such as mining stripping, equipment installation and displacement accounts for 40 percent of the pure cutting time. The amount of granite wastage mined by each diamond wire saw machine per year is about 800㎡.
There is a manufacturer in China named TOOLWITS, has 14 years experience of producing diamond tools and diamond wire saw machine for stone cutting, concrete, etc. They have rich technology and experience in granite mining and the diamond wire saw machine is good quality, competitive price and long lifespan.
