 Conexpo-2---ADM

New From ADM
Asphalt Drum Mixers, Inc. (ADM) promoted the addition of its new warm-mix asphalt system to its MileMaker™ Series asphalt plants at ConExpo. The new system delivers even more versatility to the plants, which the company says are the most fuel-efficient, mix-design flexible and productive plants within the 160 to 425 tons-per-hour range.

Previously producing only hot-mix asphalt designs, the MileMaker now has the capability to introduce water or other chemicals into liquid asphalt entering the plant, thereby appropriately lowering the temperature to warm-mix specifications.

The dual-drum plants use counterflow technology, which operates separate drying and mixing zones to achieve the maximum level of heat transfer and fuel efficiency. This enables the MileMaker to achieve a high production volume and an extremely low cost-per-ton average.

The company also showcased improvements to the design and availability of its control houses. Now featuring heavier-duty tubing construction and high-tempered tinted safety glass, the new control houses are fully insulated for any climate, while maintaining the same reliability and state-of-the-art controls found in previous models.

Conexpo-2---Flexco

Audit Program Introduced
Flexco introduced its Conveyor Audit Program to attendees at ConExpo. This comprehensive program is designed to help operations evaluate the performance of their conveyor systems, allowing them to proactively address belt conveyor concerns before they lead to costly repairs and unscheduled downtime.
When an operation participates in the Flexco Conveyor Audit Program, a Flexco field specialist will visit the operation and evaluate the entire conveyor system. Flexco says these specialists are knowledgeable experts with strong technical skills and years of hands-on training with conveyor systems and components.

Flexco also announced at the show that all of its belt conveyor cleaners are now available in stainless steel. The Flexco line of stainless steel cleaners can be used in any application, but are ideal for use in aggregate operations and other corrosive environments.


Conexpo-2---XL500

Raptor XL500 Cone Crusher Suited for Canadian Apps
Aggregates & Roadbuilding chatted at length with FLSmidth’s production team about the owner and operator benefits of the new XL500 cone crusher, a model that boasts many new design features that will eventually be rolled out to the full line. The crusher is a 24/7 machine built to handle high work index rock with a long lifespan. It has a higher throw than a conventional cone crusher, allowing for more volumetric capacity for its size. It has also been engineered to get around some of the issues that plague cone crushers of this size category, namely frame cracking. The unit has a lot of crushing force, so that the horsepower is applied to the job at hand. Thanks to an in-house gear and pinion design with spiral bezel, the XL500 can also be tailored to control fine production by slowing down, but without losing the torque required to do the job.  The unit can handle more of the crushing work that would otherwise be handled by tertiary crushers.

Conexpo-2---green

Green Machine Brings Consistent Asphalt Foaming
Gencor Industries’ Ultrafoam GX2 has a wide range of new features that allow the “Green Machine” to achieve consistent foaming at varying production rates without the use of a powdered mixing device. This allows the asphalt cement (AC) and water to be introduced at widely different flow rates and pressures, the manufacturer says. The technology uses variable orifices for both the AC and water, alongside a system that keeps the two flows in intimate contact. The bottom line is the ability to mix AC and water in a continuous fashion at various rates, providing good foaming regardless of rates. The Green Machine also generates bubbles of even size, and improves the workability of the mix. The only energy used in the process is provided by the pumping system.

Gencor also introduced the Equinox combustion system for applications requiring extremely low NOx emissions.  The design can significantly reduce or totally eliminate the use of Flue Gas Re-circulation (FGR), by a primary stage pre-mix accumulator and a second stage patented injection system. The result is a more stable combustion flame with little or no effect on the exhaust system of the process.  Gencor says this equates to more productivity with the same exhaust system.

KPI-JCI Urging Industry to be FRAP Ready
The folks at KPI-JCI were on hand promoting several new pieces of equipment to make fractioning reclaimed asphalt easier and more efficient, but in a more general sense were also promoting the use of higher percentages of recycled materials in paving jobs as a major potential bottom line booster. The company was spreading the word about a website dedicated to this topic – www.befrapready.com – where pavers can find information on the advantages of FRAP, use calculators to determine how much money they can save by increasing RAP percentages, follow case studies, and get information on some of the specific equipment available to get the job done right. The company suggests the use of a HCI Impact Crusher from KPI-JCI and Astec high-frequency mobile screens to allow operators to use as much as 50% FRAP mix. The site states annual savings of $2 million for a FRAP Ready operation that processes 300,000 tons of RAP and uses a 27/75 mix of FRAP and virgin asphalt.
