Modularity
The modularity of the BG series of batch plants delivers speed in erection and re-location. The simplified design allows plant setup in a compact area.
A modular design enables fast setup without dealing with ducts or a large number of interfaces.

Cold Feed
Setup of the cold feed bins is accomplished with minimal investment of time and money due to the modular, ready-to-launch design with optional bulkheads.
Ensure easy operation with variable speed drives, no-flow sensors, a grizzly for removal of oversize material and protection mesh on top of the feeders.
Astec cold feed bins are designed with steep walls and a self-relieving bottom to encourage smooth material flow.
For added strength, the top edges of the bins are formed into channels.
All systems can accommodate options such as grizzly bars.
Counter Flow Dryer Drum
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.
Conditioning Flights
Break up any clumps or sticky material when the aggregate first enters drum.
V-Flights
Provide greater uniformity of the aggregate veil through the gas stream during the drying process, across a wide variety of mix designs and tonnage rates.
Combustion Flights
Prevent aggregate from impinging on the flame while spreading the material to maximize radiant heat transfer.
Batch Control System
The main batch screen displays the entire batch tower with visual feedback for all processes. Ingredients not-in-use are grayed out while active channels display target and actual weights, fill levels, run command/status and material routing animations. Additionally, queued batches and an alarm log are included on the bottom of the screen.
Whisper Jet® 35 Burner
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.
Hot Elevator
The hot elevator feeds the dried aggregate to the screens. Fully-enclosed, dust-proof housing protects the integrity of the dried aggregate. The aggregate is conveyed via steel buckets with reinforced edges. Wear resistant chain ensures a long service life while split sprockets reduce the time and effort required for maintenance.
Vibrating Screen
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.
- Multi-deck design
- Linear trajectory
- Five sizes + reject
- Total screening area – 15 sq m
- Sand screen – 3.5 sq m
- Enclosed vibrator assisted
Twin Shaft Pugmill
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.
Baghouse
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.
Dust Hopper
Coarse particulates are collected in the pre-separator and transferred into the hot elevator to be screened and stored in the sand bin. Fine particulates are collected at the baghouse in a 15 tonne hopper and can be weighed in to the plant or rejected.
Recycle System
With the Astec BG 1800 Modular Batch Plant, 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.
Rap Feeder Bins
- Bin Size: 9 m3
- Loading Width: 3.5 m
- Conveyor Width: 500 mm
- Variable Feed Drive: 1.5 kW
- Feeder Capacity: up to 80 tph
Options for more than 50% up to 70%* RAP processing exist. Details on request.

Hot Bins
Extra-large hot bins add an additional 30 tonnes of aggregate capacity.
Storage Silos
With the Astec BG 1800 Modular Batch Plant, storage options can be customized to fit your needs.
Short-term storage can be accomplished with 30-tonne capacity surge bins located under the mixer unit.
Another option is storage bins or silos beside the plant.
Foreign Filler Silo
Add a foreign filler silo to weigh and transport fillers into the mixer via a screw conveyor.
