EX Series

HIGH EFFICIENCY IN A COMPACT DESIGN.
The new EX Series asphalt plants produce 100 to 425 tons per hour at a very low cost per ton, and they boast the longest aggregate drying and mixing times in the industry. The new plants are also capable of processing high percentages of RAP.

Using counterflow technology, the EX Series has separate drying and mixing zones to achieve the maximum level of heat transfer and fuel efficiency. Furthermore, this system virtually eliminates unsafe hydrocarbon emissions, which are a common problem with other drum mix plants. To make the plants even more environmentally friendly, ADM designed the system to reintroduce residual gases back to the drum’s combustion zone.

Additionally, the plants are available in portable or stationary versions. They meet all federal and state specifications and consistently produce quality asphalt to help protect operators against out-of-spec damages.

Plant controls are sophisticated in their abilities, yet simple in operation. The EX Series can be operated by just one plant operator and one loader operator. Additionally, the plants are built with durability and low maintenance in mind, so on-site staff is able to handle most breakdown issues.

FEATURES
  • Produces 100 to 425 tons per hour.
  • Has the longest aggregate drying and mixing times in the industry.
  • Provides consistent, high-quality asphalt that protects against out-of-spec damage.
  • Processes high percentages of RAP.
  • Virtually eliminates blue smoke and unsafe hydrocarbon emissions. Offers a simple design that requires just one plant operator and one loader operator.
  • Is affordable, portable and ruggedly built. Has a fast ROI; likely paid off in just two years.

Counterflow Technology

The EX Series’ unique single-drum counterflow technology utilizes separate drying and mixing zones to achieve the highest level of heat transfer and fuel efficiency. This results in high asphalt production volume at an extremely low cost-per-ton.

In our single-drum counterflow system, aggregate and superheated air move in opposite directions. Aggregate enters on the feed-entry end of the drum and travels toward the burner as it’s dried. At the burner nose, the dried material passes behind an isolation ring where liquid asphalt, baghouse dust and RAP (if used) are introduced. All materials are mixed in the final drum section, and then are discharged and conveyed to the storage silo.

Counterflow technology is productive, efficient and environmentally friendly. The design contains residual gases and reintroduces them back to the combustion zone. Combined with the separate mixing and drying zones, blue smoke and unsafe hydrocarbon emissions are virtually eliminated.

A wide range of components further customizes each plant for particular customer needs. Available individual components include cold feed bins, hot oil asphalt cement tanks (both horizontal and vertical), direct-fired horizontal cement tanks, portable and stationary bag houses, mineral filler systems, RAP systems, self-erect and stationary silos, weigh and drag conveyors, weigh batchers and fuel oil tanks.
