Plants & Plant Equipment: Terex E225P

The new Terex E225P portable counter-flow plant, the latest addition to Terex Roadbuilding’s line of super-portable asphalt plants, features 225-tph production capacities. Built for quick, low-cost portability, the plant’s base configuration can be moved in only five loads: 1) counter-flow drum mixer; 2) baghouse; 3) self-erect silo; 4) four cold-feed bins with scalping screen; and 5) liquid AC tank/control house/fuel tank. “Building on producer feedback, we designed each self-contained load for quick setup and teardown,” says Ed Montgomery, director of engineering.

At the heart of this super-portable design lies a new counter-flow drum mixer. The drum’s new flight arrangement offers more efficient aggregate heating and asphalt mixing. Producing up to 225 tph, the new E225P drum is capable of making a wide variety of mix designs, including Stone Matrix Asphalts and Superpave.

The drum is pitched at operating angle on its triple-axle chassis and has all ductwork pre-installed, significantly reducing set-up and tear-down times. A SJ-360 Hauck burner delivers 75 million BTUs of energy for dependable, efficient aggregate heating. Its patented adjustable slinger increases/decreases drum length to tailor drying and mixing time to the producer’s needs.

The base plant includes the necessary electronic connections to accept recycled asphalt, and its counter-flow technology enables the E225P drum to run higher percentages of RAP than parallel-flow designs, while still meeting tough environmental regulations. With its 78-inch diameter and 40-foot 5-inch length, the self-contained drum can be quickly moved with standard “O.D.” permits.

Featuring a 40,000-cfm capacity and a 4.5-to-1 air-to-cloth ratio, the plant’s field-proven, Roto-Aire RA218 baghouse has ample capacity to match drum mixer production. Integral to the baghouse, the fines return auger hydraulically pivots into position to interconnect the baghouse to the drum.

A self-contained 50-ton self-erect and self-weighing silo comes standard in the base plant configuration. Complete with on-board air compressor and gas tank, the silo quickly sets into operating position hydraulically. For ticketing purposes, the silo is suspended on load cells that accurately weigh the amount of stored asphalt before and after a truck is loaded.

Plant operation and asphalt mix designs are managed by the field-proven Terex Impulse X control system. Featuring big plant operation in a smaller plant controls package, Impulse X is capable of making any mix design for which the plant is configured.

The foundation of the E225P plant concept is portability. “The E225P has only 20 plug-and-play cable connections, which is significantly less than traditional portable plants,” says Mark Spicer, director of asphalt plant sales for Terex Roadbuilding’s Asphalt Plant Group. The plant is set up without the aid of a crane. All the plant’s components fit together with as little hand work as possible and most major connections are completed with the aid of hydraulics. This super-portable plant is designed to be transported and completely set up over a weekend. For more information, visit www.terexrb.com.

Hotmix Parts & Accessories
Hotmix Parts & Accessories offers quality replacement asphalt plant parts and components.

• Retrofit to existing equipment manufacturer (OEM) parts for various brands of hotmix asphalt plants
• Upgrade technology to improve existing plant components
• New accessories, such as NiteOwl plant alert

Astec Double Barrel Dryer/Mixer
The Double Barrel dryer/mixer is a combination aggregate dryer and HMA mixer that can keep RAP and virgin aggregate separate until the mixing phase of production.

• Minimizes emissions
• Ensures mix quality
• With the RAP and virgin aggregate meeting in the outer mixing chamber, excess moisture is removed from the RAP and the reclaimed liquid asphalt partially coats the virgin aggregate
