Aeroslides

RULA design, manufacture and supply aeroslides for a wide range of applications

Description

The purpose of an aeroslide conveying system is to convey fine product using very little energy by utilising the free gravity forces.

The gravity conveying is achieved by fluidisation of the product.

The fluidisation is achieved by mild steel chamber sections, with a fabric air distribution membrane sandwiched between the upper (dust) and lower (air plenum) chambers. This permeable membrane is supported by a wire mesh attached to the plenum chamber below the fabric. The upper and lower chambers are bolted together and caulked to give an airtight seal between the parts. The aeroslides are manufactured in sections with differing cross sectional dimensions. The dimensions are chosen to optimise the material flow rates within the unit, to have an even pressure deferential over the whole membrane area and to minimise wear. Each lower section is fitted with an air inlet spigot that is flanged to accept a butterfly type throttle valve. Quick release inspection hand holes and observation windows are installed at specific points for monitoring of the dust flow and the aeroslide’s internal condition.

The following products are aeroslide friendly

Alumina, Bentonite, Raw cement, Finished cement, Clay, Fly ash, Ground ores, Gypsum, Limestone, Ash dust and Silica
