Description

Technical Field

[0001] The utility model relates to the technical field of granite mining, in particular to a crushing device used for granite ore mining. Background Art

[0002] Granite is an intrusive rock in acidic (SiO2>66%) igneous rocks. It is the most common type of rock in this category, mostly light flesh-red, light gray, grayish white, etc. It has medium-coarse and fine-grained structures and blocky structures. Some are also porphyry, spheroidal, and gneiss-like structures. The main minerals are quartz, potassium feldspar, and acidic plagioclase, while the secondary minerals are biotite, hornblende, and sometimes a small amount of pyroxene. There are many types of accessory minerals, the most common of which are magnetite, titanite, zircon, apatite, tourmaline, fluorite, etc. The quartz content is the highest among all kinds of igneous rocks, ranging from 20-50%, and a few can reach 50-60%. The content of potassium feldspar is generally higher than that of plagioclase, and the ratio of the two is often that potassium feldspar accounts for two-thirds of the total amount of feldspar, and plagioclase accounts for one-third. Potassium feldspar in granite is mostly light flesh-red, and there are also grayish white and gray.
