Air Slide Chute

I. Overview

An air-slide conveyor is a conveying device that utilizes pressurized air to fluidize dry, powdery materials, allowing them to flow downward along an inclined trough under the influence of gravity. It features low capital investment and low operating costs, while offering a high conveying capacity. By optimizing the design based on the inherent operational principles of the equipment, we have expanded its scope of application and enhanced its practical effectiveness.

 II. Working Principle

The air-slide conveyor (as shown in the figure below) is constructed from steel plates. The entire trough is positioned at a specific incline along the direction of conveyance. The cross-section of the trough is divided into two sections—an upper chamber (7) and a lower chamber (9)—by a permeable layer (8). A blower (1) delivers high-pressure air into the lower chamber via an air duct. As the air passes through the porous permeable layer, it aerates and fluidizes the material fed into the upper chamber through the inlet (3). Due to the incline of the trough, the fluidized material flows downward along the trough under the influence of gravity and is discharged through the outlet (6); subsequently, the air is vented into the atmosphere through an air filter (5) located above the outlet.

III. Features

1. Simple structure, lightweight, and no moving parts.
2. Must be installed at an incline; suitable only for downward conveying.
3. Excellent sealing, noiseless operation, and minimal wear.
4. Due to fluidized conveying, material flow velocity is high, resulting in a large conveying capacity.
5. As conveying is driven by gravity, air pressure requirements are low, resulting in minimal power consumption.
6. Direction can be easily altered, making it suitable for multi-point feeding and multi-point discharge.

IV. Requirements for Conveyed Materials

1. Particle size ≤ 3 mm   

2. Moisture content ≤ 2%     

3. Density ≤ 2 × 10³ kg/m³  

4. Viscosity: None

V. Parameters

Notes:

1. A stands for the inclination angle.
2. n is a positive integer less than 8.
3. Capacity refers to the conveying capacity of cement and raw meal products.
4. Air pressure refers to the static pressure inside the lower chute.
