    MAGNESIUM PRODUCTION LINE

    ZK can provide plant design, equipment & spare parts fabrication, installation and technical support service for magnesium ingot plant & magnesium oxide production plant from dolomite calcination. The production capacity of single production line meets the customers' demand from 5,000 to 50,000 tons per year.

    Detail

    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.

    "Zinc Slag Alchemy": How does the Secondary Zinc Oxide Rotary Kiln turn Waste into Treasure?

    The crude zinc oxide rotary kiln is a core piece of equipment for processing zinc-containing materials through high-temperature calcination. Its principle is based on the physical and chemical properties of zinc compounds. Within the kiln, at temperatures of 1100-1250°C, the zinc in zinc-containing slag (such as steelmaking dust and lead-zinc slag) reacts with a reducing agent (such as coke) to produce crude zinc oxide and gaseous products.
