  • Application Areas

    Suitable for treating various types of industrial solid waste, hazardous waste, tailings, tailings slag, papermaking white mud, calcium carbide slag, aluminum ash, contaminated soil, urban medical waste, domestic sludge, municipal sludge, and acid washing sludge from the petroleum, chemical, and pesticide industries.

    Product Introduction
    Currently, the integrated solid (hazardous) waste incineration system primarily utilizes a rotary kiln combined with a secondary combustion chamber. Utilizing advanced and proven technologies from both domestic and international sources, the system determines the process route and equipment configuration based on the client's specified material characteristics. We provide customized, full-process services to ensure pollutant emissions meet current standards.

    Key Advantages
    ● Provides comprehensive services across the entire industry chain, offering complete solid (hazardous) waste treatment system solutions.
    ● Hazardous waste product advantages: High-temperature incineration achieves harmlessness, volume reduction, stabilization, and resource utilization.
    ● Solid waste product advantages: Resource recovery, waste utilization, and production of construction ceramsite.
    ● High furnace heat load ensures complete material incineration, sufficient to handle the complete incineration of large quantities of hazardous waste.

    Operating Principle
    The rotary kiln features a pusher mechanism at the feed inlet to ensure continuous feed. The kiln outlet temperature is 800-850°C. After the flue gas enters the secondary combustion chamber, secondary air is injected tangentially around the chamber, creating a strong vortex field within the chamber, ensuring the complete combustion of combustible components in the flue gas. The unique structural design of the secondary combustion chamber also enables it to function as a cyclonic dust collector. The flue gas outlet temperature exceeds 1100°C, and the flue gas resides in the high-temperature zone for more than 2 seconds, ensuring the complete decomposition of harmful components, including dioxins, and meeting the requirements for hazardous waste incineration. Solid (hazardous) waste is fed into the rotary kiln through the feeding mechanism for high-temperature incineration. After high-temperature incineration, the material is burned into high-temperature flue gas and ash. The rotation speed of the rotary kiln can be adjusted. Maintaining a stable slag layer of about 50mm thick can protect the refractory layer. Its operating temperature should be controlled at around 850℃. The high-temperature flue gas and ash enter the secondary combustion chamber from the kiln tail, and the incineration ash enters the slag discharger from the kiln tail and is regularly sent to the stabilization/solidification workshop for treatment.

  • Rotary Drum Granulator Rotary Drum Granulator
    The rotary drum granulator is a machine for processing powdered or slurry materials into pellets. Its primary operating method is wet granulation. A sufficient amount of water or steam is used to moisten the base fertilizer within the drum, allowing it to undergo a complete chemical reaction. The drum's rotational motion then creates a squeezing force between the material particles, agglomerating them into pellets. The machine boasts an attractive appearance and is suitable for both cold and hot granulation, as well as the large-scale production of high-, medium-, and low-concentration compound fertilizers.

  • Disc Pelletizer Disc Pelletizer
    The disc pelletizer is a new type of tilted disc pelletizing equipment. Its frame is welded from high-quality carbon channel steel, while the pelletizing disc is welded from high-quality carbon steel plates and channel steel, treated with other anti-corrosion treatments. The bottom is reinforced with multiple radial steel strips. The pelletizing rate can reach over 92%. The entire machine's transmission system is of paramount importance, ensuring its overall operation. The motor and reducer mounted on the drive adjustment frame are ISO/9001 certified. The motor drives the pulley, V-belt, reducer, and pinion, which in turn drives the large gear on the pelletizing disc to operate. Both large and small gears utilize high-frequency quenching, doubling their service life. The entire pelletizing disc is fixed to the drive shaft on the adjustment disc, with a taper-fit connection at the column head for a more streamlined design.
