Description of feldspar
This group of minerals consists of framework tecta silicates. Compositions of major elements in common feldspars can be expressed in terms of three end members: Potassium-Feldspar ,Albite end-member ,Anorthite end-member . The average density of feldspar is between 2.54 and 2.57g/cm3. its compressive strength usually lies about morse 6.

Application of feldspar
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkali in feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together. In the US, about 66% of feldspar is consumed in glassmaking, including glass containers and glass fiber. Pottery (including electrical insulators, sanitary ware, tableware, and tile) and other uses, such as fillers, accounted for the remainder.
Potash Feldspar Processing Plant Advantages
- 1. Mineral reserves are more abundant feldspar, potassium feldspar can be widely used in ceramic blanks, ceramic glazes, glass, porcelain, abrasive materials and other industrial sectors and manufacturing of potash with, the more quality.
- 2. These technologically advanced equipment, configuration reasonable, with good results. Feldspar crusher which because of its professional design, excellent performance is attracting attention.
- 3. Italian feldspar stone crusher broken. Feldspar is the most widely distributed and most abundant reserves of potassium minerals can be found in all parts of our country, it is often stored in acidic igneous rocks, granite Feldspar places can often be found.
Potash Feldspar Processing Plant Working Principle
Feldspar stone crusher machine is the introduction of Germany advanced technology research and development from high-performance crusher has the world advanced level. Feldspar crusher not only improves the production capacity and crushing efficiency, but also expand the range of applications extending from feldspar crushing ore crusher to the other, and efficient completion of the broken, crushing, ultra-crushing operations. Chunks of feldspar by feeding hopper by a broken feeder (jaw crusher) uniformly crushing, crushing after feldspar by belt conveyor to the second break (or cone Impact crusher crusher) for further crushing; feldspar crushing post sent by belt conveyor vibrating screen for screening, screening of several different sizes, different specifications of feldspar, feldspar meet the size requirements of the finished product conveyor belt sent the finished windrow; does not meet the size requirements of feldspar by belt conveyor feed back to Impact crusher or cone crusher for crushing again, forming a closed loop several times. Finished size can be combined and graded according to the needs of users, to protect the environment, can be equipped with auxiliary dust feldspar processing equipment.
K-feldspar (KAlSi3O8), usually referred to and orthoclase are monoclinic system, usually red meat, white or gray. The density 2.54-2.57g/cm3, specific gravity of 2.56 to 2.59g/cm3 Hardness 6, the theoretical composition SiO2 64.7% Al2O3 18.4%, 16.9% K2O. It has a low melting point (1150 ± 20 ℃), melting long interval, high melt viscosity characteristics, widely used in the the blank ceramic, ceramic glazes, glass, porcelain, and abrasive materials and other industrial sectors and the system potash.
K-feldspar mine high potassium content, the most widely distributed, and the largest reserves of non-water-soluble potassium resources. K-feldspar ore source of 60, their average potassium content of about 11.63%, and its reserves of about 7.914 billion t converted into hydroxide reserves of approximately 920 million tons, according to the average content. Anhui, Inner Mongolia, Xinjiang, Sichuan, Shanxi Province, the K-feldspar is relatively concentrated, abundant, and the advantage of local non-metallic mineral resources.
Potassium feldspar ore dressing process
Domestic K-feldspar is rich in resources, but excessive iron content, K-feldspar in addition to iron is purified. Iron is the magnetic objects, while feldspar non-magnetic material in a magnetic field, the two are very easily separated.
The potassium feldspar raw single-handedly selected a broken one grinding a finished grading a dehydration process applies to low iron content, good quality raw material. Pre-crusher for coarse crushing and fine crushing in order to prevent the contamination of the processing of iron K-feldspar, so choose grinding equipment easy turbines, pebble mill or porcelain ball mill, ultrafine laminated since the mill etc. as grinding equipment, spiral classifier ensure product granularity.
The advantages of potassium feldspar ore dressing process
Simple process,less investment, the disadvantage of this process is that the the product iron content indicators difficult to meet the requirements of high-quality ceramic products. In order to overcome the shortcomings of the process, increasing the magnetic separation process, proved choose wet high gradient magnetic separator effect in addition to iron,iron removal efficiency of 70% -90%.
Potash feldspar grinding mills applications
The machine is used to grind barite,limestione,ceramics,etc,such non-inflammable and nonexplosive stuff,which the hardness is below 9.3 Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material.The fineness size is adjustable in the range of 60-1250 mesh (it can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine.
Potash feldspar grinding mill operation
In the main frame,a 1000-1500Kg high pressure spring is fixed to the roller suspender.After the grinder is put into effect,the roller will circumgyrate around the main shaft,and rolls closely against the grinding ring effected by the high pressure is 1.2 degree than Raymond mill.
When the stuff is loaded into the grinding cavity,it is hoveled into the space between the roller and the ring for grinding.The grinded powder goes into classifier along with the circulation wind of the blower and the standard finenesspowder is guided to the cyclone collector as finished and lager size stuff falls back to the grinder for regrinding.The circulation wind returns to the blower to repeat the above process and the after wind enters into bag dust cleaner for purification.
Advantages of Popular Mineral Grinder Mill for Potash Feldspar
- 1.)Comparing with other grinder, under alike of the power condition, the output can increase 20%-30%, the roller’s pressure on account of the action of the high barometric maxima spring can increse 800-1200Kg.
- 2.)Mineral of which hardness under 9.3 stages can be fluently processed
- 3.)Completed product that particle sphere that diameter maximum is very extensive, particle is 0.613mm(30mesh), the normal particle is 0.033mm and the smallest particle is 0.013mm(1000mesh).
- 4.)The effect of the elimination dust attains the national standard.
- 5.)The grinding apparatus adopts lap multi-stage seal which is quite effective.

Recently, We is promoting advanced ore crusher-mobile crusher which is applied greatly within ore crushing industry.
Potash Feldspar Grinding Mill
The necessity of potash feldspar grinding
Reducing the size of the ore particles prior to mineral separation is called comminution. This normally takes place in stages. The first stage is primary crushing, which is followed by secondary crushing and grinding;
After being crushed by crushing machine such as jaw crusher, impact crusher and cone crusher, the crushed particles still can’t meet size requirement need to be grinded by grinding mills.
