Air Slide Working Principle
Air Slide Conveyor is a device that transports bulk materials through pipelines using airflow. It comes in three types: suction-type, pressure-type, and hybrid-type.
Working Principle:
The system uses kinetic energy of airflow to suspend and transport granular materials along the pipeline.
1. Suction-Type
-
A vacuum pump creates negative pressure, drawing materials into the suction nozzle.
-
Materials are carried through the pipeline to a separator, where they are discharged.
- The air is purified via a dust collector and released through a silencer.
✔ Pros: Simple feeding, multi-point material intake.
✖ Cons: Short conveying distance, low efficiency, high sealing requirements.
2. Pressure-Type
-
A blower forces air into the pipeline, mixing with materials from the feeder.
-
The mixture is pushed to the discharge point, where materials are separated.
-
Purified air is released after dust removal.
✔ Pros: Long-distance conveying, high efficiency, multi-point discharge.
✖ Cons: Complex structure.
3. Hybrid-Type
-
Combines suction & pressure systems for flexible operations.
⚠ Important Note:
Not suitable for large particles, high-moisture, or poorly fluidizable materials!

Conveying Capacity:
The conveying capacity of the chute is influenced by many factors and can vary significantly. Based on theoretical calculations, domestic and international reference data, and field investigations, the following values are recommended for reference when the slope is 6%:Chute Width (mm) Conveying Capacity (m³/h) 250 ~30 315 ~60 400 ~120 500 ~200 -
Slope:
-
A 6% slope is standard for straight chutes, and the slope can be adjusted freely without being affected by flange structure.
-
For coarse materials (e.g., circulating mill products), a 10% slope is recommended.
-
Generally, a steeper slope is advantageous when layout and wear conditions of the permeable layer allow.
-
-
Air Consumption:
-
1.5–3 m³/min per m² of permeable layer.
-
Air consumption is affected by material type, material condition, permeability of the layer, and chute slope.
-
A typical design value is 2 m³/min per m² of permeable layer.
-
-
Air Pressure:
-
400–600 mm water column.
-
Higher values should be selected for larger or longer chutes.
-
A typical design pressure is 500 mm water column.

An Energy-Efficient Pneumatic Conveying Solution for Powdered Materials
The air slide conveyor is an efficient powdered material conveying device based on pneumatic conveying principles. It mainly consists of an upper trough, lower trough, permeable layer, air intake device, and supporting structure. Its working principle involves injecting low-pressure air (typically 400-800Pa) through the bottom permeable layer to fluidize the material, which then flows along the inclined trough (3-10°) under gravity.
Key Features:
-
Simple Structure: No rotating parts, only trough and permeable layer form the core conveying system
-
Ultra-Low Energy Consumption: Only 0.2-0.3kWh/ton, saving 60-70% energy compared to traditional conveyors
-
Gentle Conveying: Fluidized transport with less than 0.1% material breakage rate
-
Closed & Eco-Friendly: Fully enclosed design with dust emission concentration below 5mg/m³
-
Easy Maintenance: Main maintenance involves periodic inspection of permeable layer (replacement every 3-5 years)
Wide Applications:
Cement industry (cement, fly ash), food processing (flour, starch), chemical industry (plastic pellets, pigments), etc. Particularly suitable for applications requiring long-distance (up to 100m), high-capacity, low-breakage conveying. The equipment can be designed with special configurations like multi-point feeding/discharging, and can be integrated with dust collection and automated control systems.
Our virtually maintenance-free design only requires:
