Solutions

Jiangsu Longxin has developed a new-generation ultrafine powder spray dryer specifically for lithium iron phosphate (LFP) materials. Designed to meet strict requirements for particle size, sphericity, and powder morphology, the system enables precise particle size control with typical D50 ranges of 20–30 μm or 5–10 μm. The resulting powder features high sphericity and a dense, solid spherical structure, while the equipment also offers improved drying efficiency, energy utilization, process stability, and automation for LFP battery material production.

Longxin configures high-flow pin-type bead mill systems for lithium iron phosphate slurry grinding. The route coordinates slurry feed, media separation, cooling and process control, with optional integration into storage and spray drying. Feed particle size, solids content, viscosity, target size and hourly flow rate guide equipment selection and testing.

Longxin's battery-material line links feeding, slurry preparation, high-flow pin-type nano grinding and centrifugal spray drying with powder handling and centralized controls. The grinding and drying duties are sized together from slurry properties, target particle distribution, evaporation load and production requirements; thermal processing and packaging interfaces are project options.

Longxin configures spray drying for suitable sodium-ion battery precursor or active-material slurries. Stable feed delivery, atomization, heated-air contact and powder collection are selected around solids content, viscosity, target particle characteristics and throughput. Centrifugal atomization and an air-assisted ultrafine option are evaluated as alternatives through material testing.

Longxin's MLCC and barium titanate production route combines slurry preparation, wet nano grinding, controlled atomization, spray granulation and powder collection. Grinding contact materials, cooling and atomizer type are selected for the ceramic formulation and target powder. Material testing helps verify particle size, contamination control and granule characteristics before scale-up.

Longxin's hardmetal solution uses pressure-nozzle atomization within a closed nitrogen circuit to process suitable wet-milled carbide slurries into ready-to-press granules. Slurry agitation, oxygen monitoring, powder cooling and solvent condensation are specified to the material and solvent. The nozzle, gas loop and recovery section must be engineered from the formulation and granule target.
