How we made our choices
No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager covers hundreds of products each year in its RollOuts columns and Supply Lines features. So each year, our staff reviews all the product introductions we’ve covered for the past year (our Top RollOuts “year” actually runs from the December 2005 issue through the November 2006 issue) to pick out 25 that we believe are worth further review. Our priorities are new concept products — which are rare — new series/new generation products in categories that relate to the aggregates industry, and other rollouts which serve our readers’ interests by increasing competition in a product category. Inevitably, we omit deserving products, either because we just didn’t understand the significance of the product or because the announcing company didn’t communicate what was special about the product, or both. In either case, we apologize in advance for these omissions. |

Along with the Fintec 1107 and the 1080, the company is offering the 570 Screen, which features a high-capacity 18- by 5-foot screenbox with two decks. The 570 Screen boasts an additional 5-degree screening angle built into its bottom deck, which is said to help provide 20 percent more screening area than most comparable units. The company says it also has a larger eccentric throw than most competitive models for more aggressive screening action. Click 233 on Reader Service card. More powerful loader Doosan Infracore has replaced the Mega 500 wheel loader with the new DL500, a 6.3 cubic-yard model with a 335-horsepower engine and Power Shift transmission. The new model has more power and a larger cab than its predecessor, according to the company, and improvements to the power train are said to have increased fuel efficiency. In addition to new comfort features, such as a multi-adjustable air-suspension seat, the DL500 has larger front pins and all grease points for pins and bushings are accessible from the ground. Click 244 on Reader Service card. Tier 3 articulated truck Case has rolled out the Tier 3 versions of its 27-ton 327B and 30-ton 330B articulated trucks. The new models get more horsepower than the models they replace, as well as new cab ergonomics and a number of service and maintenance upgrades. Carryover features include Case’s signature integrated differential, variable geometry turbocharger, auto warm-up system, and self-diagnosed fluid-level checks. The new 10-liter Tier 3 engines feature increased fuel pressure at cylinder entry and variable-geometry turbochargers that optimize the fuel-to-air mixture for peak performance in varying conditions. Along with new cab comforts and visibility, the new models now feature a new front suspension system to absorb shocks from rough terrain and provide a more comfortable ride. The new front driveline features an integrated transmission-mounted differential that transfers power directly from the transmission to the front wheels, eliminating a drive shaft as well as noise and vibration.

Web-based vibration monitoring InstaLink, Instantel’s newest vibration monitoring solution uses the Internet to automate the process of transferring vibration data directly from an Instantel vibration monitor to a secure, password-protected Web site for viewing by approved personnel. The new system uses the company’s Auto Call Home automated call-in feature to allow monitors to send data through a variety of modems to a PC; InstaLink then forwards the data to the secure InstaLink database. The company designed the new system for projects with time-sensitive reporting requirements, and for sites that have many monitoring points. Click 235 on Reader Service card. Fuel-efficient excavator Hitachi has rolled out a new dash-3 models in its excavator line, the 47,000-pound ZX200LC-3. The machine is powered by a 164-horsepower diesel and is said to be heavier, stronger, faster, and quieter than its predecessor, while also being more fuel efficient. The ZX200LC-3 has three new performance modes: economy, performance, and high performance; in E mode, it can get 13 percent better fuel efficiency than its dash-2 predecessor. The undercarriage, X-beam, side frames, idler brackets, and front attachment have all been made stronger to improve durability. The unit has more horsepower, swing torque, and drawbar pull, and it carries 10.6 gallons more fuel and hydraulic oil. Engine oil requirements have been reduced by one-half gallon. Also new with the dash-3 models is a larger cab with a wider seatback, more legroom, and 47 percent more glass on the right side for better visibility. Click 222 on Reader Service card. Track-mounted combo plant Terex Pegson used BAUMA to show its new 1000SR mobile plant which combines the company’s 1000 Maxtrak cone crushing plant with a double-deck screen and recirculation system, all on the same track-mounted chassis. The company recommends the new model for secondary and tertiary applications in quarrying where high quality, low flake, single-size aggregate, and “all in” sub-base materials are required.

When
we ask readers how we can best help them keep track of changes in
the products and services they use to produce aggregates, almost
everyone wants an annual short list of the really important stuff.
Metso Minerals says it designed the new
Lokotrack ST458 mobile screen for applications involving high
capacity, accuracy, and mobility. It features large (18-foot by
5-foot) screens with 85 square feet of screen area per deck and the
end-to-end crowning of the two-bearing screen boxes enables a
high-performance screening result, according to the company.
Performance is also enhanced by the screens’ ability to use both
forward and reverse movements. The ST458 employs Metso’s SmartScreen
technology, which uses the computing power of the company’s
proprietary intelligent control system. SmartScreen is said to sense
the load on the main conveyor and monitor screen functions,
automatically adjusting key parameters such as feeding and screening
speeds when necessary. Metso says this ability to control screen
functions in real time results in continuous, high-quality,
high-capacity screening.
ASGCO Manufacturing has rolled out a line of
modular impact beds that protect conveyor belts and help control
spillage in the conveyor-loading zone. The beds come in 18-inch long
units and in widths to match conveyor belts; they are closely fitted
to form the bed length needed. The company says its impact bars
allow the tightest segment fit in the industry, eliminating
materials from getting caught between bars.
W.S. Tyler designed its new Tycan
Hydro-Clean to remove silt and clay particles as small as 63 microns
from mineral mixtures, often allowing the user to avoid dumping
costs by turning waste materials into sellable material. The maximum
size of the feed material can range from 0 up to 150 mm (6 inches).
Dirty material is fed to a washing drum where high-pressure nozzles
rotate at 60 rpm and spray the material at pressures up to 2,900 psi.
The water streams are injected into holes and cracks in the rocks
that are difficult to reach with log washers, screws, and other
cleaning technologies, according to the company. The system is said
to use less water and power than any other washing system.
RhinoWire is a new composite wire screening
medium that outlasts traditional wire by four to six times,
according to Tandem Products. The company says it blends several
composite materials into a matrix to create the medium. It is said
to reduce total costs by 30 to 50 percent, to resist binding and
plugging, and to install exactly like wire cloth. It is lighter and
quieter than wire screen cloth and is recommended for both wet and
dry applications. Field trials have included dry granite and
quartzite, and results have been excellent, the company reports.
RhinoWire is available in 12 square openings ranging from 3/16 inch
to 1-1/2 inch and installs the same as wire cloth utilizing a No. 2
shrouded hook.
Case Construction Equipment has introduced
the E-series version of its 921 wheel loader, adding a Tier 3
engine, improved operator comfort and visibility, and easier
maintenance. The new engine develops 297 net horsepower in the
921E’s high-production mode and standard bucket size has been
upgraded to 5.75 cubic yards. The machine also has an “economy” work
mode to maximize fuel efficiency in light-duty work, and an “auto”
work mode in which the machine’s control system adjusts power curves
to move the maximum amount of material per pound of fuel, according
to Case. The machine’s expanded cab is quieter and visibility has
been increased.
Cedarapids says its new MACS portable
processing plants are different from other mobile plants because
they are complete, highly integrated systems that are designed to
optimize production and minimize setup time. The company says the
MACS line uses larger crushers and screens than are typically used
in track or wheeled plants. Their unique trailer designs can be
permitted for travel throughout most of the continental United
States, according to Cedarapids, with heights of less than 13 feet,
6 inches and widths less than 12 feet. Interplant conveyors are
designed into the units so separate transfer conveyors are not
required. Folding conveyors and walkways are set up using on-board
hydraulics, eliminating the need for cranes or lifts. Large,
hydraulic support legs level and stabilize the units to speed setup.
Metso Minerals heralds its new Lokotrack
LT1315 and LT1415 as an entirely new generation of mobile primary
impact crushing plants. The new models are said to combine constant
high crushing capacity (up to 900 metric tons per hour), a broad
range of process options, operator friendliness, and dust- and
noise-reduction options. The units can be transported on a standard
trailer and have low transport heights, according to Metso. They can
be equipped with a magnetic separator and pan feeder below the
crusher for trouble-free processing of recycled material containing
rebar. They use Nordberg NP Series impact crushers and can handle
medium-hard rock like limestone as well as rock-based recycled
materials.
Optibelt says its new Kraftband Super KBX-POWER
employs advanced production processes, improved materials, and
optimized molded cogs to achieve a new level in belt quality.
Compared to the conventional Optibelt KBX Kraftband, the new belt is
said to offer up to 15 percent better performance. Its very
low-stretch polyester cord construction makes it a low maintenance
belt. Optibelt says the new product makes possible space saving
designs and economic solutions, even with extremely high drive
requirements.
Telsmith says its new 3258 portable crushing
plant is more portable, more productive, easier to maintain, and
safer. The new plant travels at 13 feet, 6 inches high and 10 feet
in width, and its grizzly feeder, loading hopper, and grizzly bypass
chute comprise one modular unit that can be removed as one piece to
simplify travel in weight-restricted areas. The Telsmith 3258
hydraulic jaw crusher features a 32-inch gape and a 58-inch-wide
crushing chamber and is said to out-produce other crushers in its
class. Telsmith says its fingertip controlled hydraulic adjustment
cylinders are unique and help to reduce maintenance requirements and
increase uptime. Uptime is also enhanced by the hydraulic overload
system, which automatically protects the crusher from tramp metal.
The unit’s chassis has a standard tri-axle air ride suspension and
an optional fourth axle can be pneumatically elevated off the ground
to reduce wear and tear during tight on-site maneuvering.
Caterpillar introduced a new size class in
its mining loader lineup with the rollout of the 25-ton
(23-metric-ton) 993K. With an operating weight of 294,800 pounds and
950 net horsepower, the 993K creates a niche between the 992G and
the 994F in the Cat lineup. The company says it is perfectly matched
to two popular mining truck models: It loads the 100-ton Cat 777 in
four passes and the 150-ton 785 in six passes. Built on an all-new
platform, the 993K is the first of the K-series mining loaders and
marks the debut of a dramatic new cab, positive flow-control
hydraulics, Cat’s C32 engine, and a simplified maintenance scheme
that emphasizes more ground level access.
Davey Bickford says its new Daveytronic
Wireless Blasting System allows blasting technicians to remotely
detonate single or multiple shots from up to one mile away from the
pattern. The company says this range significantly improves safety
and exceeds minimum distance requirements. The system allows the
blast engineer to configure blasting machines in a master-slave
configuration, using the remote trigger software. Modems — one for
the master blasting machine, and one for each slave — are required
for communication between the master and slave machines. For safety,
the system’s communication protocol is protected by a Cyclic
Redundancy Check to assure a high level of data integrity.
The HP4, the first in Nordberg’s line of
high-performance cone crushers, is said to produce much finer
products with fewer crushing stages than competing units. Metso
Minerals claims it combines optimized speed with a large throw to
provide the highest reduction ratios of any cone crusher on the
market today. HP4 features include dual-acting hydraulic tramp
release cylinders that allow the unit to pass tramp iron that Metso
says would stall or damage other crushers. An advanced fastening
system for the mantle and bowl liner eliminates the need for backing
material and makes liner changes quicker. The unit has thicker
liners for longer life and Nordberg has greatly simplified the
replacement procedure.
Eaton has expanded its Fleet Resource
Manager by adding a new construction package to the Web-based fleet
management program to meet the specific mobile resource management
requirements of construction and quarry fleets. The new package uses
an in-vehicle device to record the movement of vehicles by relaying
GPS-based location information via wireless networks of servers. The
system also provides two-way text messaging between the vehicle and
its home base. It allows fleet managers to generate field service
and route compliance reports; the latter measure planned versus
actual route and work times.
KPI-JCI has introduced a new baghouse
filtering system for its Fast Trax line of track-mounted material
processing equipment. The patent-pending filter system improves
engine protection by filtering intake air before it is introduced to
the conventional air cleaner. The self-cleaning system uses
compressed air to pulsate and purge the bags of contaminants. The
company says the filter system makes it unnecessary for operators to
check and clean conventional air filters daily, reducing the
potential for failures due to improper reinstallation. KPI-JCI says
the system means conventional air cleaners only need to be changed
or cleaned at regular oil change intervals, reducing maintenance
costs.
Atlas Copco’s 5,500-pound HB 2500 hydraulic
breaker features Krupp technology in an attachment engineered for
rock mining and secondary breaking. Designed for carriers in the 29-
to 43-metric ton range, the HB 2500 can accept up to 58
gallons-per-minute hydraulic flow at 2,610 psi of pressure, and
delivers an impact rate of 550 blows per minute. It features
PowerAdapt, a proprietary new system that shuts down the breaker if
it receives excessive oil pressure from the carrier, preventing
damage to the breaker from oil flow complications that can arise
when attaching the breaker to different carriers. The unit also
features AutoControl, a monitoring system that allows the breaker to
adapt its frequency and power output to match operating conditions.
It begins by firing the first stroke at half power to create a pilot
notch that will center the working tool and prevent slippage. It
then adjusts the power output to match the density of the material,
reducing shock on both the breaker and the carrier and increasing
service life.
Terex Finlay says its new I-1312 impact
crusher plant features high throughput, large reduction ratios, and
fast set up. The multiple-speed impactor is designed for primary and
secondary crushing of limestone and asphalt and concrete rubble. It
utilizes a high-performance Cedarapids 5048LP impact crusher with a
large discharge opening and standard 3-bar or optional 4-bar
configuration. Other standard features include hydrostatic drive,
advanced electronic control system, hydraulically assisted apron
setting, grizzly feeder with integral pre-screen, selectable
discharge to bypass conveyor or main conveyor, and dust suppression
on the main conveyor.
A patent-applied-for automated Overload
Protection System is now standard equipment on all Fast Trax
track-mounted jaw and impact crushing plants from KPI-JCI. The
company says the new system optimizes plant productivity by
consistently regulating the crusher feed to prevent crusher overload
and possible plugging. An onboard diagnostic screen allows the
operator to view all the critical crusher, vibrating feeder, engine,
and system performance data in Spanish or English.
John Deere has installed Tier-3 engines in
its four-model line of articulated haulers along with other upgrades
that the company says have increased productivity and uptime. The
380-horsepower 350D and 413-horsepower 400D get compact 12-liter V6
engines and a new retarding system that works with the transmission
retarder to improve brake life. The 265-horsepower 250D and
285-horsepower 300D move up from 8.1- to 9.0-liter engines, which
the company says deliver superior fuel economy across the operating
range. The company also claims its haulers have best-in-class
payload-to-weight ratios.
Simlog has unveiled the first PC-based
off-highway truck simulator. The system was developed to put
trainees at the controls of a modern heavy hauler, providing
mission-critical skills assessment, and skills development. Even
experienced operators can use the simulator for refresher training.
The product includes six training modules of increasing difficulty;
the final module combines loading, driving, and dumping.
