Airslide fabrics for Cement processing

The Dollfus & Muller's fluidization fabrics AIRCO are used in the cement industry to secure smoothly loading/unloading bulk cement powder transport by truck (silo), train (wagon) or boat, silo discharge, mixing, storage, distribution and transport bulk cement powder.


These airslide fabrics are used for the pneumatic conveying of fine dry products like cement, also called “pulverulents”. The airslide consists of a chamber separated by a permeable cloth. The chamber is inclined at a very slight angle (as low as 1.5°). Compressed air is injected into the lower chamber which then goes through the media and “fluidises” the cement powder. The cement then behaves like a fluid and “flows” down the length of the chamber. 


The Dollfus & Muller's airslide fabrics AIRCO are used to transport solids with high flow rate over long distances. Airslides provide an efficient and low energy system with a minimum maintenance for transport bulk as well as smooth mass flow. Powder moves on the fluidization conveyor. The conveyor doesn’t move. It is the airflow through the airslide fabric that removes the friction between the powder and the textile materials : the powder flows smoothly and evenly. Energy requirements are minimal because only a small volume of air at a low pressure is required to move material.


The other names are: aero cloth, airslide canvas, airslide conveyor or belts, aeration pads, fluxo channels fluids, …..

 Airslide is a semi-permeable textile cloth which allows air to pass through but not the products.


The Dollfus & Muller's airslide AIRCO is manufactured to meet specific :

  • Permeation ranges ensuring that uniform volumes of air are allowed to pass at a given air pressure,
  • Material’s temperature. Airslide fabrics are available in few compositions:

- Polyester (filament polyester in warp, spun polyester in weft),

- Cotton, this fibre is unaffected by bacteria or organic acids, cotton absorbs humidity,

- Aramide, for high temperature end use up to 230°c.

  • Powder size,
  • Working environment
