Feldspar is one of the most abundant mineral in the earth crust and it is in some sedimentary layers and almost all igneous rocks. It is inferred, available feldspar mining beds is throughout most areas of the world and the potential availability of total mineral is also very large. According to estimates by the U.S. Bureau of Mines, the world's reserve is 1 billion tons feldspar or more. Many countries with large reserves have become exporters of feldspar, such as: Italy's Gruppo company annual production of 300,000 tons, the French company Imerys annual production of 15 million tons. Demand for feldspar is dominated by the ceramics and glass industries, accounting for more than 90%. The market is mainly concentrated in the ceramic producing countries, such as Italy, Spain, China, Southeast Asian countries and Latin America.
Generally, the potash feldspar and sodium feldspar are referred to alkali feldspar, which also the feldspar group minerals used in the industry. Feldspar mineral consists of sodium feldspar and calcium feldspar is called plagioclase feldspar. Feldspar mine content calcium feldspar and barium feldspar is called alkaline earths feldspar. In different region of the world, the type of feldspar is different, but the main feldspar quarrying equipment is basically the same. Shanghai SBM launched a series of quarrying equipment in major feldspar producing countries. Firstly, feldspar crushing plant, including PEW Jaw crusher, PFW impact crusher, CS cone crusher, HPC cone crusher, HCS cone crusher, PY cone crusher,VSI5X crusher, Hammer crusher. Secondly, feldspar grinding equipment, including LM vertical grinding mills, MTM trapezium grinder, MTW milling machine, SCM ultrafine mill, Ball mill,T130X reinforced ultrafine mill, Raymond mill. You can also adopt necessary magnetic separator, flotation machine to feldspar ore dressing.
Feldspar is aluminum silicate minerals of potassium, sodium, calcium, barium, alkaline earth metal or alkali metal. The main component of feldspar is silicon dioxide, sodium oxide, potassium oxide, calcium oxide, aluminum oxide and so on. It has a low melting point, melting time interval length and other characteristics. Now, it is widely used in chemical, glass flux, ceramic body ingredients, ceramic glaze, enamel raw materials, abrasives, glass fiber, welding and other industries. The amount of feldspar in the glass industry accounts for about 50-60% of the total amount and amount of feldspar in the ceramic industry accounts for 30%.Feldspar is mainly used in glass, ceramics and can be used to produce potassic fertilizer. The potash feldspar with better quality can be used for the manufacture of television picture tube, jade materials and so on.
The Mohs hardness of Feldspar is 6-6.5. According to the main characteristics of feldspar, Shanghai SBM launched the feldspar cone crusher. This machine break the previous design concept and design the unique structure with the eccentric shaft rotating around the fixed spindle, realizing large carrying capacity, large installed power, small size, high efficiency and low noise. The Using of full hydraulic control make it more stable, reliable, easy to operate and this also reduce downtime and can achieve full automation. With secondary and tertiary crushing cavity, it can meet all the needs of feldspar processing technology to achieve a multi-purpose machine. The laminating crushing principle makes the finished material cubic grain shape, fineness uniform, high product quality. By equipment and cavity optimization, it greatly improves crushing efficiency.
Each mined ore will have gangue. The gangue minerals of feldspar are mainly iron minerals, clay, quartz, mica, garnet, tourmaline and beryl and so on. To obtain pure feldspar, specialized processing equipment is essential. Feldspar deposit is the deposits for mining and selecting feldspar. Feldspar group minerals used in industry is soda feldspar deposit and potash feldspar deposit. In addition, amazonite which is the quality plagioclase feldspar is the jade material. Therefore, using the correct way of exploitation is an important way to protect feldspar resources. Common feldspar mining process include: feldspar deposit blasting, feldspar transport, feldspar crushing, feldspar screening, feldspar grinding and feldspar mineral feldspar.
Shanghai SBM is a professional manufacturer of mining crushing machinery and industrial milling equipment. It sets R & D, production and sales on one. All the products design, production, assembly and testing in accordance with the ISO9001: 2000 international quality system certification standards. SBM is good at developing equipment based on ore research. For the features of feldspar, SBM launched the feldspar crushing production line. As cone crusher is the main equipment, the production line also equip with the jaw crusher, impact crusher and vibrating to feeder and vibrating screen. The feldspar can be processed into a granular at about 2-5mm ore for milling. Therefore, feldspar crushing laid an important foundation for subsequent processing and application and the cone crusher improve the efficiency of feldspar quarrying fundamentally.
