Stationary Batch Plants

The batch plant is ideal for metropolitan areas requiring a large number of different mixes. Instead of a continuous mixer, these facilities use a batch tower. Bins in the top section of the tower hold dried aggregate in various sizes. Depending upon the mix needed, the bins automatically dispense the correct amount of the required aggregate. The dry material is routed to a pugmill mixer located at the bottom of the tower. Here the liquid asphalt is added. After thorough mixing, the bottom of the mixer opens and the batch is dispensed into a truck or conveyed to a storage silo.

Depending on the model Astec batch plants produce 45 to 500 tons of HMA per hour. Three model series are offered: TS, Super and BGA. Super towers and TS towers are similar in design. The larger Super tower includes extra-large aggregate bins. BGA towers are based on the proven Barber Greene design for which Astec retains all rights. BGA models are smaller in size.

Astec batch plants are the most modern, most rugged and most dependable in the world.
