An air slide conveyor is a pneumatic conveying device that transports fine bulk powders such as cement and fly ash using low-pressure air and gravity, without any moving mechanical parts. By fluidizing material on a permeable fabric membrane, air slide conveyors achieve stable, dust-free, and energy-efficient conveying. This technology is widely applied in cement plants, silo discharge systems, and continuous powder handling lines where low maintenance and long-term reliability are required.
