PULSE JET BAGHOUSE 21,000 ACFM hybrid pulse jet baghouse featuring a streamlined design for ultimate portability and functionality.

SAFETY HANDRAILS AND LADDER Safety handrails and ladder come pre-installed for added safety and ease of access. Ladders and handrails fold down for transport mode.

PRIMARY COLLECTOR (not shown in illustration)

The primary collector captures coarse dust as air flows into the baghouse. Since very few coarse particles enter the baghouse,

it can collect small fines very efficiently. Removal of coarse fines in the primary collector also reduces

wear on the bags.

ACCESS DOOR A convenient access door is located under the baghouse for easy maintenance access.

WEIGH SYSTEM The aggregate weigh system provides accuracy by using a four-point system that includes an adjustable feed gate, weigh scale, S-type tracking system and gravity take-up.

AIR RIDE SUSPENSION Air ride suspension provides a smooth ride and allows for fast setup times by raising and lowering the drum into place.

RECYCLE INLET Recycle inlet allows for producing mix with up to 30% recycled asphalt pavement. Optional recycle bins are offered in one or two bin configurations.

Achieving a quality asphalt pavement requires mixing materials correctly, with consideration given to providing sufficient time for blending. The superheated virgin materials must have adequate mixing time to bring it to temperature. The virgin aggregate, recycled asphalt, additives, baghouse fines, and virgin liquid AC must all be blended thoroughly to ensure everything is well coated and the gradation is uniform. The mixing chamber in the Unidrum mixer is an excellent mechanism to ensure adequate blending to achieve a quality mix.

FEEDER FLIGHTSMove material into the drying portion of the drum

Feeder flights guide aggregate as it enters the drum, helping it move efficiently toward the v-flights.

UNIDRUM® COUNTER FLOW DRUM

U.S. Patent No. 9,835,374

The combustion flights are constructed from heat resistant alloyed steel which lasts longer than traditional carbon steel. The flights overlap one another, creating a shield that minimizes radiant heat from hitting the drum shell, to keep it from overheating. The overlapping also reduces the opportunity for aggregate to get behind the flights and cause additional drum wear.

V-FLIGHTSProvide greater uniformity of aggregate veiling through the gas stream during the drying process, across a wide variety of mix designs and tonnage rates

The v-shaped notch allows material to start pouring out of the flights at the beginning of each revolution. The material in the flight continues to pour out until the rotation is complete. This is what provides an even veil of material. The v-flight is also larger than a traditional flight, allowing it to carry the same amount of aggregate even with the notch.

COMBUSTION FLIGHTSPrevent aggregate from impinging on the flame, while spreading the material to maximize radiant heat transfer

MIXING FLIGHTSCOMBUSTION FLIGHTSV-FLIGHTSFEEDER FLIGHTS

RECYCLE INLETA collar around the drum allows entry of recycled asphalt (RAP), additives/filler, and baghouse dust into the mixing chamber, where they are blended with the virgin material.

MIXING FLIGHTSAfter virgin and recycled materials are combined and brought up to the proper temperature, liquid asphalt is injected. Mixing flights provide increased agitation for improved mix quality.

RAP, recycled asphalt shingles (RAS), baghouse dust, and any additive/fillers enter the mixing chamber directly behind the burner nose, minimizing oxidation of the liquid asphalt from the burner flame and allowing preliminary blending before the virgin liquid asphalt is added.

LIQUID ASPHALT INLETLiquid asphalt is injected after the virgin aggregate, the recycled material, and baghouse dust are mixed. Pre-mixing these materials allows a more even distribution of the liquid asphalt cement.

Liquid asphalt is accurately metered from the storage tanks directly to the liquid asphalt inlet inside the mixing zone.

Unidrum mixing flights are engineered to comb through virgin and recycled materials to provide thorough blending before the mix exits the drum. The mixing flights are reversible to enhance mix coating if necessary.

PLANT CONTROLS

®FuryTM burner provides a robust build and simple, accessible construction. Compared to other open-fired designs, the Fury burner achieves better emissions and fuel-efficiency by putting 50% more combustion air through the burner.

PMII V CONTINUOUS MIX BLENDING CONTROL

• Store unlimited mix designs on the removable hard drive.

• Calibrate all scales, pumps and feeders from the application.

The powerful PMII V system controls and monitors proportional control of aggregate feeders and the blending of asphalt and recycled material. The flexibility of the Programmable Logic Controller (PLC) allows the control system to be easily and cost-effectively upgraded as needs change.

EFFICIENCY Rapidly swirling, high-energy air is the key to the Fury burner’s efficient combustion. The swirling air and flame are created by the fixed internal spin vanes, high-pressure blower, and high velocity nose.

COMPACT FLAME SHAPE The Fury burner cleanly and efficiently burns oil or gas. Its compact flame makes it easily compatible with the Unidrum dryer/mixer.

NO COMPRESSED AIR The Astec designed pre-filming fuel nozzle utilizes the combustion air from the high-pressure blower to atomize fuel. This eliminates the need for compressed air at the burner, and helps increase nozzle life.

RELIABILITY Each burner is also thoroughly tested before leaving the Astec burner facility to make start-up at your facility as fast as possible. For the most reliable oil light-off, even under cold and harsh conditions, the Fury burner is supplied with Astec’s exclusive heat tracing and insulation system on heavy oil burners.

BETTER EMISSIONS The Fury burner is designed to put 50% more combustion air through the burner than competitive designs with the balance of the combustion air drafted in around the burner nose. This means higher combustion quality, better emissions, and higher efficiency combustion throughout the entire firing range, than competitive burners.

PMII V Includes: Software, console, personal computer, Windows operating system, removable hard drive, backup hard drive, Ethernet data port, and a UPS power supply in the event of loss of electrical power.
