Core principle:

Positive pressure conveying tank: batch, plunger-type conveying. Material mixes with compressed air inside the tank to form a high-concentration feed plug, propelled forward by static pressure difference.

Typical characteristics

Positive pressure delivery tank

Material flow rate: Low (typically<10m/s)

Solid-to-gas ratio (mixing ratio): Very high (up to 40:1-50:1)

Energy consumption: Relatively low (small gas consumption)
