Dolomite Calcination Plant is the calcination process of dolomite, which is the first step in the process of magnesium production. We are a leading manufacturer of magnesium production line both at home and abroad, in the year of 2011, we signed an contract of annual output of 100000 tons of magnesium metal project with the world iron and steel giant Korean Pohang iron POSCO.
We can provide plant design, equipment/spare parts supply, consultation and technical service for dolomite & magnesite calcination.
- More than 50 years experience in magnesium industry.
- Design capacity of magnesium line: 5,000-25,000 tons per year.
- Professional Process Design Engineers, Equipment Engineers, Electrical Engineers.
- Leading supplier of magnesium production line, and we take up over 90% of the market share.
Raw Material
1) Dolomite
The dolomite size should be from 10 ~ 40mm, and the part above 40mm and lower than 10mm shall not exceed 5%. The maximum particle size should be less than 50mm.
The chemical composition of dolomite:
MgO: 19-21%, CaO: 30-33%, SiO2<0.5%, Fe2O3 <0.5%, Al2O3 <0.5%, Na2O <0.005%, K2O <0.005%, Mn <0.0005%, CaO / MgO = 1.394 (Mass ratio), CaO / MgO = 1.0 (molar ratio).
2) Ferrosilicon
Ferrosilicon selected with Si ≥ 75%, that is, composed of 49.92% Si and 50.08% FeSi2 75 # ferrosilicon.
3) Fluorite powder
Fluorite powder CaF2> 90%, the particle size of 200 mesh.
Process introduction: As a result of mining dolomite is too large in volume,So crushing and calcining bulk dolomite, make its become particles.
Main Products: Jaw Crusher,Conveyor,Vibrating screen,Vertical preheater,Rotary kiln,Vertical cooler,etc.
