ONGOAL TECH's one-stop solution for ternary cathode materials in the energy manufacturing industry encompasses the entire process, from planning and design to custom software, engineering contracting, installation, commissioning, and after-sales services. This comprehensive approach supports the battery materials industry in achieving automation, intelligence, and digital production.

The system is designed as a standardized process for ternary cathode material production, involving various stages such as feeding, mixing, sintering, crushing, wet coating, and final product packing.

First Mixing Process:

Within the temperature and humidity-controlled feeding area, the raw materials are unpacked from big bags and stored in corresponding temporary storage bins. Based on the material characteristics, suitable storage bins and fluidization devices are chosen, with all storage bins equipped with exhaust filters to efficiently collect dust and facilitate material reutilization. The weighing process adopts a loss-in-weight metering method, and an automatic batching program sets the precise dosing values for each material, ensuring accurate delivery to the mixing system below.

The ploughshare mixer, a self-developed equipment by ONGOAL TECH, features high capacity and shorter mixing time, ensuring uniform mixing for larger batch sizes. After mixing, the materials enter the ribbon mixer for temporary storage, which not only prevents material stratification but also enables dual discharge without the need for additional reversing devices.

First Sintering Process:

Following mixing, the materials proceed to the primary sintering process. After sintering and coarse crushing, the materials are cooled and then conveyed to the next process.

The process utilizes positive pressure dense-phase pneumatic conveying, achieving a material-to-air ratio of over 50:1, and the minimum conveying velocity can be lower than 4m/s, minimizing material loss during conveying.

Crushing Process:

The materials in temporary storage undergo iron removal and screening before entering either an air jet mill or a mechanical mill for crushing. After crushing, the materials undergo second iron removal and screening before being conveyed to the next stage through positive pressure conveying.

Wet Coating Process:

Following water washing and pressure filtration, the materials are rapidly dried using a kettle dryer. Low-speed stirring is employed to avoid damaging the coating layer and increasing the rate of fine powder due to particle squeezing and collisions.

After drying, the materials are cooled in the ribbon mixer and then conveyed to the second mixing process after screening through positive pressure conveying.

Second Mixing Process:

After precise metering and mixing using the ploughshare mixer, the materials proceed to the second sintering process.

Second Sintering Process:

Following the second sintering, the materials are conveyed to the final product treatment process.

Final Product Treatment Process:

In this system, all storage bins are equipped with inflation protection devices to prevent the final product from coming into contact with external air. The materials are batch mixed using the ribbon mixer, and after mixing, they undergo screening and iron removal through ultrasonic vibrating screens and electromagnetic separators. Finally, the materials are packed using an integrated big bag packing machine, which enables functions such as bag inflation, weighing, reinspection, compaction, heat sealing, and automatic conveying.

An intelligent control system monitors and dynamically manages the entire production process in real-time. All process equipment is divided based on functional zones to ensure stable and reliable system operation.
