Double Barrel® Mixers The Double Barrel® mixer uses a unique, energy-efficient system to dry aggregate and mix HMA. The Double Barrel's inner dryer drum rotates inside a stationary shell. Mixing paddles are attached to the outside of the dryer drum. As the dryer drum turns, it functions as the shaft of a large pug mill mixer.
	Drum Mix Coaters Retrofitting an existing stationary facility with an Astec drum mix coaters (DMC) overcomes the problem many conventional mixers have with hydrocarbons and blue smoke. The coater does the mixing, leaving the drum mixer to function only as a dryer.
	Parallel-Flow Drum Mixers Astec's parallel-flow drum mixer is recommended where initial cost of the equipment is an overriding consideration. It is quite suitable for applications where air pollution codes are less restrictive and high percentages of RAP will not be used.
	Aggregate Dryers Astec aggregate dryers feature the same quality construction found on the Double Barrel®. Stationary dryers are used mainly with batch plant facilities. Along with a low pressure oil burner, these units come with the blower burner, automatic burner controls, burner platform, fuel oil pump and ignition platform.
	TS Batch Towers The batch tower and hot elevator assembly includes a 3-1/2 deck screen, four hot bins, manual sampling system, aggregate weigh hopper, and liquid asphalt weigh bucket.
	BGA Batch Towers Astec offers the BGA batch tower series from Barber-Greene. These batch towers, now built by Astec, are smaller than the TS models and popular on the international market. Five different BGA towers are available with batch ratings from one to five tons in portable or stationary version.
	Super Towers Super Towers can have as many as 14 bins, providing an amazing 800 tons of hot aggregate storage. This can provide enough rock to run all day without having to replenish the bins.
	Post Drum Mixers Post Drum Mixers are powerful pugmill mixers which incorporate dried aggregate and liquid asphalt to make hot mix asphalt. They can be used as stand-alone units or in combination with a dryer.
	Lime Pugmills Lime is often mixed with aggregate to achieve a stronger bond between the rocks and the liquid asphalt. Astec lime pugmills premix the lime and the aggregate before the aggregate enters the dryer.
