A batch plant with an Astec Coater II can run two HMA production lines, one mixing in batches and the other in continuous runs. The dual-shaft Coater II comes in nine different sizes. Coaters can produce up to 725 tons per hour. These facilities are also outfitted with either a surge bin or a storage silo, a diverter chute for the dryer, weigh bridges for the cold feed bins, and related controls. Existing batch facilities can be retrofitted with the coater as a stand-alone unit.
