Attracting almost 120,000 attendees and more than 2,400 exhibitors, ConExpo 2011, held in Las Vegas in March, was the place to see anything new in the aggregates and roadbuilding businesses. We brought you lots of news in our last issue and now we have more. Read on for the latest from ConExpo 2011.
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.
In addition to having lots of hardware on the floor, Chattanooga, TN-based Astec, Inc. (Astec) exhibited two 1/8th scale models at ConExpo – one of a relocatable hot mix asphalt facility and one of a portable facility.
The company designs, manufactures and markets a complete line of hot-mix asphalt facilities, components and parts as well as soil remediation equipment. Astec also exhibited the new Double Barrel Green system for producing mix at lower temperatures, eliminating smoke and smell, reducing fuel consumption and increasing production.
Big Show from Atlas Copco
Atlas Copco had a huge presence at ConExpo 2011. Teaming up with its other brand – Dynapac, the two companies shared connected space, which provided drill and blast and road construction customers a complete look at compaction and paving equipment, along with new drills for site preparation.
For the quarry crowd, the company’s new rock crushers, rock drills, hydraulic breakers and compressors were popular, with the new Powercrusher line of rock crushers and screeners attracting lots of attention. ConExpo attendees were among the first to see Atlas Copco’s new line of track-mounted mobile crushers and screeners suitable for demolition, quarrying and road construction applications. The Powercrusher range includes four models of jaw crushers, six impact crushers, a cone crusher, and six models of screeners.

It features a large cross-section upper and lower shock-absorbing isolators to reduce vibration feedback to the carrier; a front head restraint system to tightly guide the front head within the housing; a 12,000-lb. working weight suited for use on 120,000- to 220,000-lb. carriers; manual frequency control via hydraulic piloted stroke control; and a narrow box housing design.
Deister Offers Uptime with Portable Screen Plants
Deister Machine Co. ‘s portable horizontal vibrating screening plants include design features for extended life and uptime in 6 x 20 and 8 x 20 screening plants. Built for sand and gravel, crushed stone, asphalt recycling or concrete applications, the plants use heavy-duty horizontal triple-shaft vibrating screens on a walking beam tri-axle suspension, with AR400 plate construction or linings on all chutes and hoppers. Uptime features include centralized grease points, access ladders and walkways on both sides and front of the screen, and self-cleaning wing-type tail pulleys. Material handling is via 60-in undersize conveyors below the screen and 30-in motorized head pulley cross conveyors. Options include 42-in screen feed conveyor, four-leg hydraulic leveling package, spring-loaded belt scrapers and more.
Eliminate Settling Ponds
Derrick Equipment Company showcased a number of products at the show, including its DE-7200 VFD Centrifuge. Designed to eliminate settling ponds, the DE-7200 VFD is designed to dewater thicker underflow.
It offers a reduced footprint, less chemical usage, is easy to operate and requires no operator involvement, reduced downtime and maintenance costs, low operating costs per ton, and consistently produces a stackable and conveyable product.
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.
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.
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.
New Orange Machines
Hitachi Construction brought some new gear to the show this year, including the ZX290LC-5 and the ZX870LC-5. These ZX Dash-5 Series machines continue the long-standing Hitachi tradition of being reliable, smooth, fuel-efficient, and quiet. They incorporate customer-driven features sure to provide superior durability and productivity while keeping operating costs low.
The Dash-5s offer a host of features, including improved arm digging force, bucket digging force, lift capacity, swing speed, swing torque, hydraulic flow, engine horsepower, and drawbar pull (varies by model).
The roomier cab has more side-to-side foot room and a larger door with more glass for better visibility to the side, while the new, more comfortable high-back seat is available as a heated, air-suspension version (optional on the ZX250–ZX350, standard on the ZX470 and higher). A new multifunction monitor provides enhanced diagnostic features and integrates the radio and HVAC controls in one place.

The unique combination of continuous rotation and side tilt lets you approach your job from any angle and in tight work areas. Rototilt is available in a complete range of models for machines from 3 to 30 tonne capacity.
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.
LB Performance Targets Off-Highway Jobs
Born from the VT LeeBoy heritage and in collaboration with Volvo Construction Equipment, LB Performance offers a full line of niche paving gear under the Blaw-Knox name geared for off-highway paving professionals, including municipal and private jobs.
