China quarry direct sale granite slab polished 18/20mm xiamen service
Granites belong to intrusive rocks in acidic (SiO2>66%) magmatic rocks. This is the most common rock in this category, mostly shallow flesh red, pale gray, gray white. Medium coarse grain, fine grain structure, massive structure. There are also some speckle structures, spherical structures, like flax like structures, etc.
250000Cubic meters quarry reserves, the granite quality will be better and better when digging deeper from top to the bottom. The slab factory will be put into production at August 2018.
In general, the mining of granite is made of wire sawing. There are new technologies such as dense drainage and flame injection. Flame spray method of mining stone cutting neat, no injury, high production efficiency. Pick stones with coarse whole called blocks, followed by artificial drilling or sawing machine to carve, prepared bulk, plates with required size; milling machine or lathe machining, a cylindrical or arc shape; the artificial cut coarse and fine grains of rock drilling, grinding, or by machine the surface polishing, crystal clear. Granite does not pollute the environment. Synthetic materials are often accompanied by bad or even toxic by-products, which need to be replaced several times during the construction period. Granite does not need to be replaced because it is very durable.
In addition, granite is very practical and can be made into a variety of surfaces - polishing, sublight, and fine.Since granite is often contained in radioactive materials, it is necessary to measure the level of radiation when using granite and reconfirm its use.
