Gneiss is a medium to coarse-grained, semi schistose metamorphic rock. It is characterized by alternating light and dark bands differing in mineral composition (coarser grained than schist). The lighter bands contain mostly quartz and feldspar, the darker often contain biotite, hornblende, garnet or graphite. The minerals are orientated due to schistosity. In behalf of the origin source of rock, gneiss can be dividedinto two kinds: orthogneiss is formed by the metamorphism of igneous rocks, paragneiss results from the metamorphism of sedimentaryrocks. Gneiss usually has little tendency to split along its planes, some para- or orthogneisses split easily to slabs. In buildingindustry,stoneis mostly described as “granite”.
In recent years, flour processing industry gradually has become very hot. Gneiss after crushing grinding process can be applied into many fieldsto achieve significant economic benefits. In general, jaw crusher, aggregate stone crusher, impact crusher, vibrating feeder, vibrating screen, sand washing machine, belt conveyor, etc. can be composed of a complete gneiss processing plant.
In the gneiss actual production, common crushing equipment has jaw crusher, impact crusher, cone crusher and so on. Different crushers have different types. Each typehas specific application field and specific working principle. Gneiss crushing plants manufacturer equipment is special for aggregate production line with the necessary device of Shanghai Shibang manufactures which is of reliability, reasonable design, simply operation and high efficiency.
Shang Shibangjaw crusheris mainly used for coarse crushing and medium crushing in the fields of mining, building materials and infrastructure construction. According to the feeding width, it can be divided into large, medium and small sized. The jaw crushers have many advantages such as simple structure, easy manufacturing, reliable working condition and convenient operation and maintenance.
In the gneiss actual production, milling machine has many types. Common milling equipment includes Raymond mill, superfine grinding mill, ball mill as well as the successful production of the new euro milling machine application. As is known to all, the grinding process of grinding mill is by milling equipment using energy to extrusion, impact and grinding of ore, make useful minerals in the ore monomer cleavage, under the mineral phases choose other process.
Raymond mill is mainly used to grind and process variety kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry, etc. Raymond mill is ideal grinding machine to grind and process the materials such as limestone, gypsum, barite, carbonate calcium, marble, feldspar, dolomite, granite, kaolin, bentonite, bauxite, etc.
