Preparation of magnesia dolomite, magnesium if you want to ensure the purity of the calcined dolomite should follow the following principles: 1, using different calcination equipment (vertical kiln or Rotary Kiln), you should choose a different intensity of dolomite; 2, the low temperature to a high temperature should be raised slowly to achieve the decomposition of dolomite, which can not only reduce the calcination temperature, but also reducing energy consumption; 3 should reduce the concentration of the calcined product with a surface pressure of CO2 gas, CO2 gas or discharge acceleration speed, in order to facilitate the decomposition of dolomite; 4, should be based on chemical composition or structure of the mineral dolomite, controlling the calcination temperature to ensure calcined dolomite having a large chemical activity.
