SALT PROCESSING EQUIPMENT
Rotary Air Lock
Discharges fine salt collected in the powder cyclone while maintaining the air-handling process.
Discuss this equipment
PROSALT · Salt Drying Plant
How it works
Discharges fine salt collected in the powder cyclone while maintaining the air-handling process. It helps prevent accumulation and reduces salt loss.
Its place in the process
The air lock transfers collected solids while limiting unwanted air exchange between connected parts of the recovery circuit. It is commonly considered at a cyclone discharge, where solids flow and pressure conditions need to remain coordinated.

Equipment questions
Is an air lock simply another conveyor?
It transfers solids but also has a pressure-separation role. The required leakage behaviour, clearances and discharge conditions distinguish its selection from ordinary conveying equipment.
Can this equipment be integrated into an existing salt plant?
A retrofit is assessed from the existing process flow, material analysis, available dimensions and utility connections. The upstream and downstream equipment must be reviewed together before the scope is agreed.
