Why Capacity Calculation Is Critical for Air Slide Conveyors
Capacity calculation plays a central role in determining whether an air slide conveyor system will operate reliably over time. Unlike mechanical conveyors, air slide conveyors rely on fluidized material flow driven by gravity and low-pressure air.
If the conveyor capacity is incorrectly sized, common problems such as unstable flow, material accumulation, or excessive air consumption may occur.

Key Parameters Required for Capacity Calculation
Before performing any calculation, the following parameters must be clearly defined.
Material Properties
- Bulk density (static and aerated)
- Particle size distribution
- Moisture content
- Flowability characteristics
Fine powders such as cement, fly ash, and raw meal are particularly suitable for air slide conveying due to their good fluidization behavior.
👉 powder flow and fluidization principles
Conveyor Geometry
- Air slide trough width
- Effective material bed height
- Total conveying length
Wider air slides allow higher capacities but require more precise air distribution control.
Inclination Angle
The inclination angle directly influences conveying velocity and stability.
- Typical design range: 3°–8°
- Steeper angles increase capacity but reduce flow stability
Air Supply Conditions
- Low-pressure air volume
- Uniform air distribution beneath the aeration fabric
- Stable blower performance
Improper air supply design often leads to inefficient fluidization and capacity loss.

Basic Capacity Calculation Principle
The conveying capacity of an air slide conveyor can be estimated using the following simplified relationship:
Capacity = Material flow cross-section × Flow velocity × Aerated bulk density
Where:
- Cross-section depends on trough width and bed height
- Flow velocity is affected by air supply and slope
- Aerated bulk density is lower than static density due to fluidization
⚠️ Important:
Using static bulk density instead of aerated density is one of the most common causes of capacity miscalculation.
Typical Capacity Ranges for Cement Applications
In cement plants, air slide conveyors are commonly used for:
- Cement discharge
- Fly ash conveying
- Raw meal transport
While capacity varies by design, air slide conveyors are best suited for continuous, moderate-to-high throughput of fine powders.

Common Mistakes in Air Slide Conveyor Capacity Sizing
Many operational issues are caused by incorrect assumptions during capacity calculation:
- ❌ Using static bulk density instead of aerated density
- ❌ Ignoring moisture variation in material
- ❌ Oversizing air supply without flow verification
- ❌ Designing excessive inclination angles
These mistakes often result in unstable operation and unnecessary energy consumption.

Capacity Calculation and System Design Integration
Capacity calculation should never be performed in isolation. It must be integrated with:
- Overall system layout
- Aeration fabric selection
- Air supply and blower sizing
A properly calculated capacity ensures efficient system design and long-term operational stability.

When Capacity Recalculation Is Required
Capacity recalculation is recommended when:
- Material type or composition changes
- Moisture content increases
- Conveying distance is extended
- Plant throughput is upgraded
Ignoring recalculation can lead to frequent operational interruptions.
From an engineering perspective, proper air slide conveyor capacity calculation is essential to balance conveying efficiency, air consumption, and long-term system stability in cement and bulk powder handling applications.
