    MAGNESIUM OXIDE (MgO) PLANT

    The calcination of magnesite to produce magnesium oxide requires MgO>45%, SiO2<1.2 and CaO<1.5% for the ores used for calcination. The essence of magnesite calcination is the decomposition of carbonate: MgCO;=MgO+CO2.

    ALUMINUM ASH PROCESSING SYSTEM

    Harmless aluminum ash hazardous waste disposal program: through acid leaching, alkaline leaching, washing, etc., the nitride, fluoride, salt and other impurities in the secondary aluminum ash are removed to obtain harmless aluminum ash before safe filling Buried. Recycling process: After removing toxic and harmful substances, the secondary aluminum ash is processed by high temperature or cold processing to produce different products such as steel claw protection ring, brown corundum abrasive, refining agent and water purifying agent, etc., or return to the electrolytic cell as electrolytic aluminum raw material.

    ACTIVE LIME PRODUCTION LINE

    Active lime is made from minerals with high calcium carbonate content, such as limestone, dolomite, and chalk, which are calcined at 1000-1100°C. The choice of active lime production process is determined by many factors: investment cost, lime activity requirements, fuel selection, raw material size, system capacity requirements, and environmental protection requirements. We will determine the production process according to the customer's specific conditions and requirements.
