Air slide conveyors, also known as air gravity conveyors or fluid slide conveyors, have become an integral part of material handling systems across a wide range of industries. These innovative devices offer a unique method of transporting dry bulk materials efficiently and reliably.

What is an Air Slide Conveyor

An air slide conveyor is a pneumatic-based conveying system that utilizes a combination of low-pressure air and gravity to move powders, granules, and other dry materials. Unlike traditional conveyors that rely on mechanical components, air slide conveyors use air permeation through a porous fabric to create an air cushion that supports and transports the material.

Working Mechanism: Air Permeation: The air slide conveyor system consists of a rectangular trough or channel with a permeable fabric or membrane as the conveying medium. Low-pressure air is supplied from below the fabric, forming a thin film of air between the fabric and the material being transported.

Fluidization: As the air flows through the permeable fabric, it fluidizes the material by aerating the particles, reducing friction and allowing them to flow more easily.

Top 4 Applications of Air Slide Conveyors

Air slide conveyors find applications in various industries due to their unique advantages and capabilities. Some notable applications include:

  • Cement Industry: Air slide conveyors are widely used in cement manufacturing plants for efficiently transporting cement, raw materials, and finished products within the production process.
  • Chemical Industry: Air slide conveyors are suitable for handling powdered chemicals, pigments, and dyestuffs, ensuring gentle handling and preventing material segregation during transportation.
  • Food Processing: Air slide conveyors play a vital role in the food industry, facilitating the movement of powdered ingredients, such as flour, sugar, and spices, in a hygienic and contamination-free manner.
  • Mining and Minerals: Air slide conveyors aid in the transportation of minerals, ores, and powders within mining operations, reducing the risk of material degradation and dust generation.

Top 4 Advantages of Air Slide Conveyors

  • Efficient Material Flow: With the use of air permeation, air slide conveyors provide a smooth and consistent flow of bulk materials, minimizing blockages and ensuring reliable transportation.
  • Low Maintenance: Air slide conveyors have a simple design with fewer mechanical components, resulting in reduced maintenance requirements and lower operating costs.
  • Dust-Free Operation: The fluidization of materials in air slide conveyors significantly reduces dust emissions, improving workplace safety and hygiene.
  • Versatility: Air slide conveyors can handle a wide range of materials and particle sizes, making them adaptable to various industries and applications.
