Granite (Granite), one of the main constituent rocks of the earth's crust,which is a kind of igneous rock formed by magma condensation below the earth's surface, mainly composed of feldspar and quartz. The etymology of granite is the Latin word granum, meaning grain or granule. Because granite is a plutonic rock, it can often form well-developed and discernible mineral particles, so it gets its name. Granite is a deep-forming acidic igneous rock formed by magma condensation in the deep underground, and some granite is gneiss or migmatized rock formed by metamorphism of magma and sedimentary rocks. Granite is mainly composed of feldspar, quartz, biotite and so on, and the content of quartz is 10%-50%. The content of feldspar is about 2 /3, which is divided into orthoclase, plagioclase (alkali lime) and microplagioclase (potash). The mineral composition of different varieties is different, and there may be pyroxene and hornblende.
At present, the domestic granite processing equipment and granite crushing production line equipment technology has been quite mature. Yusheng Machine Sand Stone Project Department has the configuration of production line projects for granite production customers in many regions of the country, the crushing production process of granite can generally choose two-stage crushing production technology, the first stage chooses jaw crusher, the second stage chooses impact crusher, of course, circular vibrating screen can be used to separate 1-2, 2-4, 4-8 inch different specifications of stones to meet different building needs.
Yusheng Machine granite crusher has large crushing ratio, high output, uniform particle size, simple structure, convenient maintenance, low production cost, etc.; Yusheng granite crusher has a full range of models and a variety of types, and can be customized to meet customer requirements according to customer needs. The granite crushing production line designed and produced by Yusheng Machine is mainly composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor, centralized electric control and other equipment.
In order to meet the different processing needs of customers, it can be equipped with cone crusher, dust removal equipment and so on. The design output is generally 50-500 tons per hour.
The bulk stone is uniformly sent to the jaw crusher by vibrating feeder for coarse crushing, the coarse crushed stone is sent by the belt conveyor to impact crusher for further crushing; the finely crushed stone is sent to the vibrating screen by the belt conveyor to screen out several kinds of stones of different specifications, and the stones that meet the particle size requirements are sent to the finished product pile by the finished belt conveyor. The stones that do not meet the particle size requirements are returned by the belt conveyor and sent to the impact crusher for re-crushing, forming closed-circuit circulation for many times. The particle size of the finished product can be combined and graded according to the needs of users, and auxiliary dust removal equipment can be equipped to protect the environment.
Granite gravel is a high-quality and widely used building stone, because granite is hard and difficult to be eroded by acid, alkali or weathering, and granite is rich in resources and widely distributed. 9% of the land in China (about 800,000 square kilometers) is granite rock mass. Granite has the characteristics of high compressive strength, low crushing value, strong corrosion resistance, good asphalt adhesion and so on. It is widely recognized as the best stone material for the construction of roads, railways and airport runways. Because of its many pores and hard characteristics, mixing it into concrete can reduce the weight of concrete without losing firmness. At the same time, it has the advantages of sound insulation and heat insulation, so it has become a high-quality aggregate for lightweight concrete in high-rise buildings. Granite stones can be used to make mortar and concrete according to different stone specifications. 1-2, 2-4 and 4-8 inch are all very common stone specifications. China's infrastructure construction can't stop, the domestic granite market has been extremely hot, which has become a major driving force for the development of China's stone machinery industry.
