To ensure the biomass magnesite products quality
In recent ten years, our country magnesium products obtained rapid development, but there are also many problems, one of the main problem is that the quality is not stable, and the reasons are various, but for now the most critical reasons are the stability of the raw materials and the scientific and reasonable ingredients. Stable quality production of the raw material of magnesium products develops until today, the major investment in technology, processes, equipment are mainly on the magnesium products, and its production of raw materials for decades has made little progress, even some setbacks. The key is light burning magnesium oxide. But for now a real threat to magnesite product long-term stability is that light burning magnesium oxide composition fluctuation is large and directly affects the accuracy of magnesite product ingredients. There are two feasible ways to solve this problem.

1, the systematic solution:
 
After knowing detailed information of distribution of the mineral resource, according to the requirement of the user, light burning magnesium oxide factory explores mining separately or collocation exploration. The crusher transshipment ascends the mine into raw material storage of the factory. Loading materials is put into the mill according to the measurement. The raw material after choosing is put into homogenization library, then through stirring into the suspension calcining kiln. The calcination kiln is burned by coal powder provided by the coal mill. Direct calcinations with gas is also ok, the materials out of the suspension calcining kiln are put into homogenization after dust settling and cooling as the finished product. The material is entered into the finished-product stock piling up with 6 mouth packing machine.

Another method, using the level 3 suspension decomposition and vertical cooling machine, this method can reduce the part of the equipment investment, but the heat consumption is slightly higher.

2, partial solutions
 
Without changing the existing magnesium oxide production mode, adopting the Raymond mill plus a homogenization method, also can make a library of material composition uniform, as shown in figure 3:

The advantages are less investment and quick effect. Drawback is corresponding products can not be produced according to the plan and the requirement, and completely decided by kiln ore. It can't be comprehensively used, and burning is not stable, heat consumption is high.

Each kind of multicomponent reaction product has its specific reaction proportion, for magnesium materials, the main group of MgO, MgCl2 and H2O ternary system, and the proportion of each component in the system are not necessarily set in stone. According to different requirements, different mixture ratios can be used. But in principle, the ratio between the MgO and MgCl2 remains the same in a particular area, and the addition quantity of H2O depends on the kinds of product and demand. People have considered the recipe mysterious. Actually, each factory can take the test to grope for a suitable techniques and material formula for their own, now the formula calculation method introduced as follows (using active magnesium oxide as ingredients benchmark): 

1, determine the content of active magnesium oxide in the light burning magnesium oxide, set to a
2, determine ratio scheme of the mixture, for example, MgO: MgCl2: H2O mole ratio was 6.5:1:18
3, check the periodic table to determine the molecular weight of each ingredient
MgO = 40.3         MgCl2 = 95            H2O = 18


1, calculation: 1 kg light burning magnesium oxide, including active magnesium oxide content is a, then:
 
          a
  MgCl2 ≈ —————×95 ≈ 0.363a
       40.3×6.5
 
      a×18×18
  H2O ≈ —————— ≈ 1.237a
      40.3×6.5


(MgCl2+H2O) that means amount of brine is 0.363a+1.237a=1.6a
 
While the concentration of brine is:

     0.363a
  —————×100% ≈ 22.7%
   1.6a


also means wave degree of magnesium 22.7(wave degree of magnesium refers to content)
 
 
Conclusion: There are many factors which affect magnesium products, but mainly are the stability of the material and rational and scientific ratio. Through the above analysis it can be seen that:
1, the adoption of advanced production method completely can produce high quality and stable light burned magnesia, and cost does not rise but lower, to increase one-time investment, of course.
2, scientific ingredients refers to the needs of different products, which can meet the needs of industrial production completely.
