PORTABLE COUNTER-FLOW DRUM MIXER

E225P/E275P PORTABLE COUNTER-FLOW DRUM MIXER The portable E225P/E275P drum mixer is designed to provide high-quality hot mix asphalt. This is part of the family of counter-flow drum mixers that incorporates the latest in counter-flow technology and is capable of meeting the most stringent air quality regulations, providing improved mix quality and lower cost per ton.

The E225P/E275P drum mixer moves virgin aggregates and RAP materials counter to the flow of the exhaust gas inside the drum. Virgin aggregate is dried and heated by the exhaust gas in front of the burner flame. The aggregate then moves behind the flame into a mixing chamber that is isolated from the hot gas stream. It is here that the liquid asphalt, additives, fines and RAP materials are added to the mix. The drum mixer is 7 ft (2.13 m) diameter x 40 ft (12.19 m) long and constructed of high-strength/low-alloy steel plate.

Specially designed flight arrangement begins with material intake distribution flights, which feed the aggregate drying flights. The unique design of the combustion flights keeps material out and away from the burner flame, allowing for complete combustion.

The E225P/E275P has a recycle inlet for the introduction of processed, crushed and reclaimed pavement material. Recycle entry flights help guide recycled material out and away from the recycled entry collar toward the mixing and high-lift discharge flights.

Collected baghouse particles are conveyed back to the mixing chamber with a 10 in (.25 m) diameter drum injection screw conveyor powered by a 10 hp (7.46 kW) motor.

STANDARD EQUIPMENTREVERSIBLE SLINGER FEEDER

Aggregate is introduced “live” into the drum by a 24 in (609.6 mm) wide slinger conveyor driven by a 5 hp (3.73 kW) motor. Slinger is manually indexed. Conveyor assembly includes heat-resistant belting with recessed splice.

FINES RETURN AUGER

Collected baghouse particles are returned to the mixing chamber 10 in (254 mm) diameter screw conveyor powered by a 10 hp (7.46 kW) motor. Liquid asphalt pipe enters through the discharge housing.

SIDE ENTRY RECYCLE INLET

Inlet chute assembly and outer collar assembly are mounted to the main frame. Widow entry ports installed in the shell, complete with proportioning flights to direct reclaimed material into the drum at a point downstream of the burner.

STARJET “HAUCK” BURNER SJ-360 (E225P) SJ-520 (E275P)

Provides high-efficiency combustion for maximum BTU availability for heat transfer. The high-pressure turbo produces more induced primary air, thus creating maximum heat release with minimum secondary air requirement. A skid-mounted pump is furnished for fuel oil supply.

AUTOMATIC BURNER CONTROL

Performs all operational functions and sequential checks before firing through automatic production cycles and subsequent shutdown with a minimum of operator intervention. A unique two-stage control system allows automatic burner proportioning for the utmost accuracy. Both mix temperature and exhaust temperature are monitored and provide necessary input for proper positioning of the burner control motor.

AUTOMATIC ASPHALT PROPORTIONING

Provided by a 2 in (.05 m) Viking pump A/C variable frequency drive, strainer and secondary pump with pick up to meter asphalt cement supply to the drum mixer. Calibration valve, sample valve and positive flow switch are included.
