Spray drying is a method of systematic technology applied to material drying. Utilizing the high-speed rotation of the atomizing disk in the horizontal direction, centrifugal force is applied to the slurry, causing it to be thrown out at high centrifugal speed. After atomizing the slurry in the drying chamber, the water rapidly vaporizes upon contact with the hot air, resulting in a dried product. This method can directly dry solutions and emulsions into powdered or granular products, eliminating evaporation and other processes.

Protective sintering is a core process in the production of lithium iron phosphate. The sintering process of lithium iron phosphate must be carried out in an inert environment. To prevent product oxidation, a high-purity nitrogen atmosphere is continuously introduced into the furnace to ensure a nitrogen environment inside. To ensure the uniformity of the material during sintering, a graphite bowl with good thermal conductivity is used as the carrier. The empty graphite crucible is transported by the automatic line of the track furnace to the automatic loading machine, which is then filled with material and conveyed to the furnace head. It enters the furnace body at a uniform speed for heating and sintering, and after passing through the set sintering process temperature zone, it enters the cooling section. After the material cools to a certain temperature, the crucible carrying the material is transported out of the furnace and into the automatic loop line. The loop line passes through an automatic tipping machine, where the material is transported to the next section through negative pressure, and the empty crucible is continuously reused through the automatic line. In addition, customized heating curves developed by technical personnel have increased production capacity by more than 40% compared to conventional equipment, effectively reducing product costs.

The crushing and packaging process is the last step in the entire production line. The entire crushing and packaging production process can be monitored in real time through the intelligent MES system in the central control roocm of the production workshop. The digital MES system can collect real-time production data from the control points of each section on site, realize centralized display and data collation and analysis, and implement loop control, parameter adjustment, and signal alarm for each section of process equipment. It is currently a powerful management tool for the management of lithium iron phosphate production workshops.
