Product Highlights

Narrow particle size distribution

Fluctuation within ± 1 ℃ in the constant temperature zone, ensuring D50 deviation ≤ 3% and increasing tap density by 15%.

Waste heat recycling

The nitrogen preheating and recovery system reduces the nitrogen consumption per ton of material to 150m ³/h.

Zero blockage guarantee

Special design of roller rod coupling+box bowl air-cooled cooling, continuous operation for more than 50 days without furnace jamming.

Dust leakage rate<1mg/m ³

Fully enclosed structure+negative pressure bag dust removal, lithium dust recovery rate>99.9%.

Explosion proof design

Inert gas circulation+real-time monitoring of oxygen concentration, suitable for handling flammable materials.

Reduce energy consumption by 40%~50%

Lightweight insulation materials (ceramic fibers+mullite bricks) reduce heat loss, with insulation power ≤ 200kW.
