About Granite Stone, You Want To Know Here

    Granite, the main component of the continental crust, is a igneous rock formed by the condensation of magma below the surface, belonging to deep intrusive rocks. The main ingredients are feldspar, mica and quartz. The source of granite is the Latin granum, meaning grain or granules. Because granite is a plutonic rock, it often forms well-developed, visible-grained mineral particles, hence the name. Granite is not easy to weather, beautiful in color, and its appearance can be kept for more than 100 years. Due to its high hardness and wear resistance, it is used as the first choice for high-end architectural decoration projects, hall floors, and open-air carving. Granite is a decorative stone that is often used in life. It has a wide range of applications and a wide variety of products. You may want to know what the granite sheet processing process is, and the price of granite sheets is not expensive. Let's take a look at the granite sheet metal processing technology and process, let you have a deeper understanding of the price of granite sheet.

  [Granite words interpretation]    

  1. A kind of igneous rock, which is the most widely distributed in the earth's crust. It is a crystalline rock mass that is gradually cooled and condensed in the depths of the earth's crust. The main components are quartz, feldspar and mica. It is usually yellow with pink and grayish white. The texture is hard and the color is beautiful. It is a good building material. Known as? Granite.

  2. The metaphor is stubborn: the granite head.

  [Granite Classification]


    According to the types of minerals, it can be divided into black granite, muscovite granite, hornblende granite and phlogopite granite. According to structural structure, it can be divided into fine-grained granite, medium-grained granite, coarse-grained granite, porphyritic granite and plaque-like granite. , crystal cave granite and gneissic granite and black sand granite.

    According to the sub-minerals, it can be divided into cassiterite-rich granite, strontium-bearing iron ore, strontium-bearing granite, lithium mica granite, tourmaline granite and so on. Common long-Petrochemical, Yunying lithification, electrical and petrochemical and other self-metamorphism.

    Granite is a widely distributed rock that is produced in all geological times. Most of the forms are rock foundations, rock strains, rock bells, and the like.

  [Granite sheet processing technology]


    The main processing methods of granite are not complicated, mainly: sawing, grinding, polishing, cutting, chiseling, singeing, auxiliary processing and inspection.

     1. Saw cutting: Saw cutting is a semi-finished product in which a granite block is sawn into a wool board (generally 20 mm or 10 mm thick) or a strip shape or a block shape by a saw machine.

    2, grinding and polishing: the purpose of grinding and polishing is to further process the sawed wool board to make its thickness, flatness and gloss meet the requirements.

    3. Cutting and cutting: Cutting and cutting is to cut and process the wool or polishing plate according to the required size.

    4. Chiseling and cutting: Chiseling and cutting is a traditional processing method. The blank is processed into the desired product by means of wedge cracking, chiseling, boring, refurbishing and grinding.

    5, singeing processing: singeing processing, also known as fire processing, burning processing, is the use of different mineral particles composed of granite differences in thermal expansion coefficient, using flame spray to make some of the surface of the particles thermal expansion and rupture, forming ups and downs Orderly rough grained.

    6. Auxiliary processing: Auxiliary processing is to educe, chamfer, open holes, drill holes, mill slots, milling edges, etc.

    7. Inspection and repair: All granite plates need to be inspected after processing. Firstly, they should be cleaned, then blown dry, and the qualified products should be packed into the warehouse. Unqualified products should be selected first. In the case of meeting the order requirements, for some defects, the granite products can be repaired, that is, bonded and repaired, thereby reducing the scrap rate.

  [Processing Process of Granite Sheet Processing]

  The processing of granite sheet products mainly has four production lines: specification board production line, thin plate production line, rough surface decorative board production line and profiled plate production line. Specification board processing process: block hoisting → sawing → rinsing inspection → rough grinding → fine grinding → fine grinding → polishing → cutting repair → inspection packaging; sheet processing process: block hoisting → sawing into thin sheet → truncated → Grinding polishing → cutting → edging, chamfering, milling repair, cleaning, drying → inspection packaging; granite rough surface decorative board processing process: semi-finished wool board → chiseling or singeing → cutting → inspection packaging; Processing process: semi-finished sheet → trimming → profile milling → drilling → edging chamfer → inspection packaging.


[Granite plate price]

  There are many kinds of granite plates, single materials, different price differences due to different materials, origins and grades, generally ranging from tens of dollars to more than one hundred yuan per square. As for the specific price, it is recommended that consumers go to the physical store to find a suitable granite plate.
