The Battery Material Vacuum Screw Conical Dryer is widely used in the lithium battery industry for efficient drying of cathode materials, anode materials, battery slurry intermediates, and fine chemical powders. With low-temperature vacuum drying technology, this equipment ensures high purity, low moisture content, and uniform mixing during the drying process, making it ideal for sensitive battery materials such as lithium iron phosphate (LFP), NCM, graphite, and silicon-based powders.
As a professional industrial drying equipment manufacturer, Jiangsu Jinling Drying Technology Co., Ltd. provides advanced vacuum conical screw dryers designed for the growing EV battery and energy storage industries.
A vacuum screw conical dryer is a multifunctional drying system that combines vacuum drying, mixing, and powder handling in one sealed machine. The equipment uses a conical vessel and internal screw agitator to continuously lift and tumble materials while heating under vacuum conditions.
This drying method is especially suitable for:
Lithium battery cathode materials
Anode materials
Conductive powders
Battery precursor materials
Fine chemical powders
Heat-sensitive materials
Solvent recovery applications
The system minimizes oxidation and contamination while improving drying uniformity and energy efficiency.
In lithium battery manufacturing, excessive moisture can seriously affect battery performance, cycle life, and safety. A vacuum conical screw dryer can achieve ultra-low moisture levels while protecting sensitive active materials.
Uniform powder drying
Low residual moisture
Closed-system operation
Reduced contamination risk
Improved product purity
Efficient solvent evaporation
Low-temperature drying process
Battery materials such as lithium salts and metal oxides are highly sensitive to oxygen and humidity. Vacuum drying helps reduce oxidation during processing.
Lithium Iron Phosphate (LFP)
NCM/NCA Cathode Materials
Graphite Powder
Silicon Anode Materials
Lithium Carbonate
Conductive Carbon Black
Battery Precursors
The vacuum screw conical dryer operates using indirect heating and vacuum evaporation technology.
Wet battery powder is loaded into the conical chamber through a sealed feeding system.
The jacketed vessel heats the material while vacuum pressure lowers the boiling point of moisture and solvents.
The rotating screw continuously lifts and mixes the powder, ensuring even heat transfer and preventing agglomeration.
Evaporated moisture or solvents are condensed and recovered through the vacuum system. After drying, the finished material is discharged automatically.
The closed structure prevents dust leakage and external contamination, meeting high-purity battery production requirements.
Vacuum operation allows drying at lower temperatures, protecting heat-sensitive lithium battery materials.
The combined mixing and heating system improves thermal efficiency and shortens drying time.
Organic solvents used in battery material production can be safely recovered and recycled.
The screw agitation system ensures consistent moisture content throughout the powder batch.
