Potassium feldspar mine belongs to monocline brilliant department, show the scene such as fleshy red Huang Bai normally. Density 2.54-2.57g/cm3, it is the quantity that contain potassium taller, distributing the blame water-solubility with the widest, the largest reserve potassium resource. Specific gravity 2.56 ～ 2.59, hardness 6, its theory composition is SiO2 64.7%Al2O3 18.4% , k2O 16.9% . Have melting point low (1150±20 ℃ ) , melt time interval is long, melt viscosity is advanced characteristic, the industrial department such as porcelain of frit of preform of porcelain of wide application Yu Tao, pottery and porcelain, glass, report, abrade material and make potash fertilizer use.
Potassium feldspar is in our country reserve is very substantial, and distributinging range is wider, be like and other places of Fujian, Sichuan, Anhui, Shanxi, Inner Mongolia, Xinjiang, its reserves amounts to 7.914 billion tons about. Accordingly, technological process of potassium feldspar mineral separation gets the attention of a lot of people, article SBM machine is here to be shared together with everybody.
Above all the main measure that we will come to say technological process of potassium feldspar mineral separation simply, explain by measure fractionize again next.
Principle of job of product line of potassium feldspar mineral separation is: Use potassium feldspar crusher broken, broken the stock after sends platen to sift screening, granuality sends for the grain under 6 millimeter grind machine is abrade into fine pink, 20-200 purpose fine pink stock sends helix chute, undertake depart grading, single out silt.
The stock of silt of the take out after classics is grading sends table, wash a 3 oxidation 2 iron; take out 3 oxidation the stock of 2 iron sends machine of strong magnetism reelect to undertake concentration, single out iron, micaceous material, send weak magnetism magnetic separation plane stock next, single out iron, micaceous material again, send high frequency vibrating separator to choose the stock that passes reelect and general election, the 3 oxidation in eliminate makings pink 2 iron and 4 oxidation 3 iron, receive potassium feldspar fine powder.
With vitriolic regard pickling as the agent, according to acerbity chroma and potassium feldspar the quantity containing iron of fine pink undertakes ticking off add, in vitriolic chroma affirmatory circumstance falls, the quantity containing iron of potassium feldspar fine pink and add vitriolic weight become direct ratio, classics pickling gets rid of thoroughly 3 oxidation 2 iron and 4 oxidation 3 iron, depart gives vitriolic and ferrous solution, receive powder of potassium feldspar essence, potassium feldspar pink of essence of life sends 20-200 eye sieve screening, the content below the sieve is iron content under the finished product of 0.24% .
To here principle of job of product line of potassium feldspar mineral separation explains end, want to understand technological process of potassium feldspar mineral separation to divide measure detailed to solve, continue to pay close attention to please below piece.
