Even with a compact design, the Terex E100P boasts big-plant features. It is capable of making virtually any mix design for which the plant is configured at production capacities of up to 100 tph (91 t) at 5 percent moisture.

The Terex E100P asphalt plant is a single/dual load, super-portable plant featuring counterflow drum mixer technology. In its standard configuration, the compact E100P positions all plant components — counterflow drum mixer, baghouse, cold-feed bins, discharge and aggregate conveyors, scalping screen and control house — on a single chassis.

Companies can mobilize the entire asphalt plant in a matter of two days, lowering transport costs and making it the right plant for low-tonnage jobs. Its design requires a small footprint, enabling producers to position the plant closer to the job site and save on trucking costs, according to the manufacturer.

Even with a compact design, the Terex E100P boasts big-plant features. It is capable of making virtually any mix design for which the plant is configured at production capacities of up to 100 tph (91 t) at 5 percent moisture. Numerous options, including the Terex warm mix asphalt system that lowers mix temperatures as much as 90F (32C), increase the plant’s flexibility. Components such as the available portable RAP unit and mineral filler silo can be added to the base plant configuration to increase mix design versatility.

A 5-ft., 11-in. (1.8 m) diameter counterflow drum mixer with early-entry RAP collar and Hauck SJ4260 burner serve as the core of the E100P plant. The drum’s external rotary mixer is positioned at operating angle on the chassis and features two mixing zones for more thorough coating of the aggregate. The first zone mixes liquid asphalt with larger aggregates, while finer aggregates are coated in the second zone. The binder is mixed with aggregate behind the burner, so any gasses resulting from the mixing process are incinerated by the burner flame.

Unique to single/dual load portable plants, the E100P features a pulse-jet baghouse for enhanced emissions control. A compact knockout box positioned at the entrance of the baghouse removes up to 80 percent of the larger particles from the airflow, improving filtering efficiency. A total of 480 Nomex, high-temperature bags capture the fine particles with a 5:1 air-to-cloth ratio.

Each of the plant’s four 7.0 cu. yd. (5.5 cu m) side-by-side aggregate bins feature 12-ft. 6-in. (3.8 m) widths for easy loading by a standard front end loader. If required to meet local weight restrictions, an optional plant configuration removes the cold-feed bins from the chassis for two-load plant portability. Each bin features two vibrators to prevent material bridging for efficient material flow. V-shaped feed belts can be removed for servicing without component disassembly.

The standard discharge conveyor pivots into operating position and features pneumatic gate opening of the 1-ton (0.91 t) batcher. The drag slat conveyor’s toothed design kneads material to deliver continuous mixing up to the batcher, reducing segregation. As an alternative to the batcher, producers can equip the plant with the Terex SE20, SE50 or SE195 self-erect silo for asphalt surge capacity.

The plant’s air conditioned control house is located to provide an unobstructed view of truck loading, while positioning it far enough away from the aggregate bins to reduce dust infiltration. The same Impulse controls package found on larger Terex portable and relocatable asphalt plants operates the E100P, allowing for virtually infinite storage of mix designs.
