I.　Raw　Material:　

Magnesite　or　hydromagnesite　

II.　Principle:　

Conduct　pretreatment　of　magnesite　or　hydromagnesite,　resolve　it　through　pulverizing　and　calcination　and　convert　into　magnesium　oxide,　and　produce　light-burned　magnesium　oxide　powder　through　pulverizing　and　packaging.　

III.　Chemical　Reaction:　

MgCO3→MgO+CO2↑　-　121KJ

CaCO3→CaO+CO2↑　-　177.94KJ

IV.　Consumption:　(calculated　according　to　1,000kg　finished　products)

Magnesite　2-2.5T;　coal　0.18-0.4T;　and　electricity　30-50Kw.h

V.　Main　Equipment:　

Crushing　equipment,　vertical　calcining　kiln　(or　rotary　calcining　kiln),　powder　preparing　equipment,　packer,　etc.　

VI.　Light-burned　Magnesium　Oxide　Mass　Indicator:　

VII.　Form　of　cooperation:　

Technical　transfer.　Taking　responsibility　for　process　flow　design,　supporting　equipment　of　standard　equipment,　non-standard　equipment　manufacture　design,　equipment is　plane　layout　design,　equipment　installation　design,　pipe　network　design,　equipment　installation　guidance,　equipment　commissioning,　production　commissioning,　training　for　production　engineers,　analysis　staff　and　technicians,　process　operation　specifications,　raw　material　and　product　analysis　method,　and　preparation　of　intermediate　control　analysis　method;　ensuring　output,　yield　and　quality　to　reach　the　standard;　and　undertaking　turn-key　projects.
