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.
The production line for roasting and acidizing lithium ore with lepidolite, spodumene and other raw materials configured by our company has excellent product performance, stable production condition and easy operation, which has received positive recognition from users. The kiln adopts wireless temperature monitoring system and remote intelligent variable speed kiln condition control system, which is convenient for production personnel to adjust kiln condition in real time. The raw material crystal conversion rate is high, the acidification is complete, and the lithium leaching rate and lithium recovery rate are 15% higher than the traditional process.
We have complete set of process technology and core equipment R & D and manufacturing technology, and committed to the R & D and application of new technologies in the field of gypsum building materials.
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 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.
ZK Corp provide complete solution for active lime project, energy saving rotary lime kiln process, vertical lime kiln process, lime grinding plant, lime slaking plant, etc.
