Airslide™ Aeration Unit Packages
Each Airslide Aeration Unit Package consists of standard FLSmidth 8-inch (200 mm) open type Airslide conveyor units in lengths of 5 and 10 feet (1.5 and 3 m) depending on the slope length of the conical storage area. Each package consists of three or six Airslide conveyor units for layout as three or six spoke patterns. Three spoke patterns are normally used with materials which have good fluidizable characteristics. Six spoke patterns provide maximum aeration for difficult materials which can be fluidized.
Airslide conveyor units have been successfully used in handling fine, dry materials such as cement, gypsum, soda ash, fly ash and dusts, barites, bentonite, hydrated lime, ground limestone, ground ores, alumina, alumina hydrate, catalysts, silica, phosphates, talc, detergent and soap powder, calcined magnesite and other materials. Material should be generally no less than 40 percent passing 200 mesh.
Each unit is a standard 8-inch (200 mm) Airslide conveyor unit [10-inch (250 mm) installation width] constructed of fabricated steel plate covered with a specially woven polyester fabric which can handle materials up to 350°F (175°C).
A source of clean, dry air is required. Minimum SCFM for each package is listed. Pressures should be 3 - 5 PSIG (.21 - .35 Kg/cm2) minimum at the aeration unit. Blower units, such as Sutorbilt/Roots blower units offered by FLSmidth, are a reliable, economical source of air for the aeration packages.
Floor-mounted aeration units are normally used for installation on the flat or sloping floor of silos and are constructed with a pressed steel casing into which the aeration plate is cemented.
Flange-mounted aeration units employ a cast iron casing with flanged face for surface mounting on the bin cone or slope sheets.
Both types utilize a porous ceramic plate as the basic aeration element and are fitted with standard pipe connections to admit the fluidizing air.
The aeration units can be used with materials up to 400°F (200°C). Units also feature replaceable filter elements for greater economy.
Air requirements:15 cfm (0.42 cmm) at 3 psi (0.21 Kg/cm2)
Airslide® Observation Ports
Simple mechanical design and construction using a cast iron base mounting and cover with steel tee bolt and hold down bar. Rotating the hold down bar counterclockwise permits cover removal. Reverse procedure locks bar against cast integral catches on the mounting. Turning the threaded tee bolt increases or decreases pressure on the cover and the bar against the catches. The cover uses an “O” ring seal made of “Buna N” synthetic material to form a tight seal.
FLSmidth can make available ports constructed of stainless steel and other materials to meet specific customer requirements.
Airslide® Railcar Breather/Filter
The FLSmidth Airslide Car Breather is constructed of corrosion resistant aluminum and stainless steel for all weather applications.
The breather is mounted on one of the open loading hatches the Airslide Car and is fitted with lugs to permit secure clamping in position using the hatch cover bolts.
The breather uses a replaceable woven Dacron fabric filter element with high permeability and filtering efficiency up to 300 CFM. Larger air volumes will require additional breathers on the car.
