Astec drag conveyors are shipped completely assembled.

Sturdy construction withstands the tough environment of a hot mix asphalt facility.

Optional additive silos are used to hold a variety of mix additives.

Separate RAP into two sizes for more efficient use.

Drag Conveyor And Storage Silos

Astec HMA storage systems fit any size storage need. The silos feature a steep 66° cone angle which provides segregation-free loadout through mass flow. Astec silos also feature better insulation than competitor's models, so they have the ability to store product for four days without loss of mix quality.

Depending on the size of the silo, legs and batchers are mounted to the silos at the site. Plates at the bottom of the silo legs attach to anchors set in concrete. The drag conveyor comes completely assembled except for the top service platform, which is installed on-site. The conveyor is then raised and attached at the top of the silos. Weld plates set in concrete stabilize the bottom of the drag conveyor.

The Additive System And Fines Silo

Silos for fines, mineral fillers and other dry additives come in a range of sizes and with a number of metering options. Plates at the bottom of silo legs are embedded in concrete to stabilize these tall structures.

Rap Bins And Rap Conveyor

The Reclaimed Asphalt Pavement (RAP) bins ship as a single module including a skid foundation. An upturned end attaches to its collecting conveyor and goes to the scalping screen of the RAP conveyor. The standard system comes with one bin, with additional bins offered as an option. A separate RAP conveyor with scalping screen is included in the standard system. An optional closed loop RAP crusher system is also available.
