Astec BG Series Batch Plants

The powerful, well-balanced, high-efficiency drum is insulated and features Astec v-flights to enhance heat transfer into the aggregate. A single chassis supports the drying drum. The four-wheeled dryer drum drive is friction driven.

Mixing takes place in a 1800 kg mixer with synchronized double shafts. Specially-alloyed cast iron components are highly resistant to abrasion. Specially-designed tips and shanks ensure a homogeneous mix within a short span of time. A full-length discharge gate driven by an electro-pneumatic jack allows fast and complete emptying of the mixer.

The Astec Whisper Jet total-air burner uses unique patented technology to burn cleanly and efficiently. A proven Astec design ensures best-in-class efficiency and performance. Pre-testing and wiring guarantees performance and delivery. Available in a variety of fuel firing combinations.

The modular reverse pulse baghouse is fitted directly over the dryer to eliminate ductwork. The baghouse utilizes two-stage filtration with a primary collector which separates coarse material from the gas stream and protects the bags from abrasion. The dust-laden gas then enters the baghouse where the dust collects on the heat-resistant meta aramid bags. Pneumatically operated cylinders clean bags a row at a time. Collected dust can be stored or returned to the mix.

Reclaimed Asphalt Pavement (RAP) can be incorporated into mix via the dryer drum or through the mixer unit. When added via the dryer drum, the RAP is added to the aggregate in the drum through a RAP collar. When added via the mixer, RAP is fed into a surge hopper on the batching tower.

Cold feed bins are designed with steep walls and a self-relieving bottom to encourage smooth material flow. Variable speed drives, and no-flow sensors ensure easy operation, Optional grizzly bars are also available.

Driven by two vibrating motors, the multi-deck screening unit properly sorts aggregates into five different hot aggregate bins. A maintenance-free design eliminates the need for lubrication points, while an easy grid exchange system reduces the time and effort to change screens.

Extra-large hot bins add an additional 30 tonnes of aggregate capacity.
