Aeration Pad for Cement, Fly Ash & Powder Conveying Systems
(Kotak Aerasi / Aeration Box untuk Sistem Konveyor Semen, Abu Terbang & Bubuk)
High-efficiency aeration pad solution designed to improve powder flow and prevent silo blockage
Overview
Aeration pads, also known as aeration boxes, are critical components in cement silo aeration systems and bulk powder discharge applications. Installed at silo cones, hoppers, and discharge points, aeration pads introduce low-pressure air through a fluidizing membrane to reduce internal friction and improve powder flowability.
For fine bulk materials such as cement, fly ash, clinker dust, and lime powder, aeration pads help prevent common flow problems including material bridging, rat-holing, arching, and silo blockage. By stabilizing material flow, aeration pads ensure continuous discharge, protect downstream conveying equipment, and improve overall system reliability.
✅ Stable and controlled powder flow in cement silos
✅ Effective silo blockage prevention solution
✅ Low air consumption and energy-efficient operation
✅ Suitable for continuous industrial operation in cement plants
Ideal for cement, fly ash, lime powder, clinker dust and other fine bulk powders.
Aeration pads are commonly integrated with air slide conveyors, flow control gates, and bulk loading systems to ensure stable and continuous powder discharge.
How Aeration Pads Improve Silo Material Flow and Prevent Blockage
Aeration pads improve silo discharge performance by creating a controlled fluidized layer at the material–wall interface. When low-pressure air passes evenly through the aeration fabric, fine powders temporarily behave like a fluid, reducing cohesion and internal friction.
As a result, aeration pads:
✅ Eliminate material bridging and rat-holing in cement silos
✅ Enable stable and continuous bulk powder discharge
✅ Improve unloading efficiency for trucks, railcars, and bulk loaders
✅ Reduce mechanical stress on flow control gates and downstream conveyors
This makes aeration pads an essential component of cement silo aeration systems, fly ash storage systems, and bulk powder handling lines.

FAQs About Aeration Pad
What is an aeration pad used for in cement silos?
An aeration pad is used to improve powder flow inside cement silos by introducing low-pressure air through a fluidizing membrane. It helps prevent material bridging, rat-holing, and blockage during silo discharge, ensuring stable and continuous material flow.
Is an aeration pad the same as an aeration box?
Yes. In cement and bulk material handling industries, aeration pad and aeration box are often used interchangeably. Both refer to the same aeration device installed at silo cones, hoppers, or discharge points to fluidize fine powders and improve flowability.
What materials are suitable for aeration pad systems?
Aeration pads are suitable for cement, fly ash, lime powder, clinker dust, and other fine bulk powders. They are widely used in cement plants, powder storage silos, pneumatic conveying systems, and bulk material discharge applications.
How does an aeration pad differ from mechanical agitators?
An aeration pad improves material flow by introducing low-pressure air to fluidize fine powders, without moving parts.
Compared with mechanical agitators or vibrators, aeration pads consume less energy, require minimal maintenance, and avoid material degradation or equipment wear, making them ideal for continuous cement and fly ash discharge applications.
Can aeration pads be customized for different silo designs?
Yes. Aeration pads can be customized in size, air permeability, housing material, and installation layout to match different silo cones, hoppers, and discharge geometries.
LVRUI provides aeration box solutions tailored to cement silos, fly ash silos, powder hoppers, and bulk material handling systems.
How do you choose the right aeration pad for a cement silo?
Selecting the right aeration pad depends on powder properties, silo geometry, discharge rate, and air supply conditions. For cement and fly ash silos, key factors include air permeability of the membrane, pad size and layout, operating pressure, and installation position inside the silo cone. Proper selection ensures stable flow, low energy consumption, and long service life.
