The breaking utilization of granite by new sand making machine

Granitic rocks are one of the main rocks that make up the continental crust. Granitic rocks are widely distributed in China. In the southeast and northeast, the distribution is more concentrated. The exposed area of granite in the southeast region is more than 200,000 km3, equivalent to 20% of the total area of the southeast region.
Due to the characteristics of granite, the application of granite is more and more, the characteristics of the new vsi sand making machine structure granite, the use of high manganese steel lining plate and hammer head, fully broken granite, so that the granitic type of granite uniform, in modern engineering construction more applications.
The main minerals in granite are quartz and feldspar. Without them or without one of them, granite cannot be named. The quartz content in granite is about 20%-50%. Feldspar content is about 60%-70%, mainly potassium feldspar, plagioclase as the second. The dark minerals are mainly biotite, with occasional Muscovite, and common amphibole or (and) pyroxene. Granite is divided into two species according to plagioclase: if plagioclase is more feldspar or sodium feldspar, known as calc-alkaline granite; If it is sodium feldspar and contains alkaline dark minerals (such as sodium amphibolite, sodium ferroamphibolite and aegirine pyroxene, etc.), it is called alkaline granite.
Granite is mainly distributed in the upper layer of continental crust, and can be divided into shallow zone rock mass, middle zone rock mass and deep zone rock mass according to the depth of rock mass formation. Shallow-zone rock mass has obvious cross-shear relationship with surrounding rock, and is sometimes associated with the same volcanic rock, which is called sub-volcanic granite. Some yanshanian granite in the eastern coastal area of China belongs to this category. Most of the mid-belt rock masses have large basement and are generally complex, often emplacement in the center of the compound anticlinal axis or the camber structure. The deep zone rock mass is usually orogenic, and the surrounding rocks are generally amphibolite facies to granulite facies, which are often associated with various types of mixed rocks. The occurrence of granite usually includes granite camber, rock foundation, rock plant, rock cover and rock wall, etc.
Because granite is widely distributed in the fold belt of different times and the shield area of precold period, it has been subjected to strong geological tectonic stress for many times, rock and minerals have undergone strong deformation, and a variety of dislocations have occurred in the crystals. The dislocation density can reach 108-10 times bearing error/cm2 (such as quartz crystal), and energy is stored (> In the lattice, the stored energy can be as high as 5.85j /g, and generally as high as 2.09-5.02j /g. Therefore, granite sometimes shows the alkali activity of slow reaction, but the reaction significantly appears the extension time of expansion and cracking, often continues to 30-50 years, should be vigilant. There are many projects abroad due to the use of granite aggregate expansion damage.
Broken granite new sand-making machine, the structure of the new sand-making machine is simple, the operation, the price is cheaper than the same functional products, is a good choice for granite crushing plant.
