From Eagle Crusher Company
UltraTraxx™, Eagle Crusher Company’s latest product innovation, came on the market May 2016. This portable impactor track unit, equipped with the company’s UltraMax® UM-15 impactor, is designed for ultra-mobile crushing on the job site.
To keep producers up and crushing, UltraTraxx has fuel capacity for more than 10 hours of operation. The UM-15 impactor provides the industry’s only lifetime rotor warranty (North America only) on its solid-steel, three-bar, sculptured rotor for minimum downtown. The load-sensing hydraulics improve fuel efficiency and reduce component wear for lower operating costs and minimum downtime as well, according to the manufacturer.
Helping producers achieve their highest production rates, the UltraTraxx all-hydraulic, hydrostatic-drive system allows independent operation of the conveyors, feeders and impactor. Material processing efficiency is maximized by the UltraTraxx smart feeder drive system by monitoring engine load for more efficient production and product consistency.
Further enhancing production rates, the UltraTraxx dual-motor, under-crusher pan feeder, with discharge clearance of more than 20 inches, provides greater material flow and maximizes uptime by virtually eliminating clogging, according to the manufacturer.
UltraTraxx high torque drives ensure superior tramming and gradability, enabling the unit to track while crushing, so operators can continue stockpiling and also maximize production. Uptime is maximized with the UltraTraxx on board hydraulic cooling fan that reverses to minimize heat exchanger clogs.
Thoughtfully designed maintenance features also help provide maximum uptime and include the easily removable discharge conveyor for quick access to the under-crusher area for inspection, maintenance, and cleaning. With the discharge conveyor removed, operators can also quickly inspect and maintain the conveyor. The discharge conveyor is fitted with one of the plant’s easy-access grease banks for lubricating the head and tail pulley bearings, and the conveyor folds for transport or to remain out of the way for more compact storage when not in use.
To help ensure the highest quality spec product, UltraTraxx is equipped with a permanent, cross-belt magnet to remove steel contaminants from crushed material. The magnet is reversible to allow steel to discharge from either side of the unit, and the magnet does not need to be removed for transport.
The UltraTraxx heavy-duty hopper is sized for feeding with a loader or excavator, and the unit has a discharge conveyor height of 12 feet 5 inches for feeding directly into an optional screener.
The UltraTraxx includes a wireless remote control to operate and monitor plant functions including filter status, hydraulic oil temperature, engine load and charge pump pressure. The control can be tethered to the unit for operation if the remote battery loses its charge. Typically, a charge will last 8 to 10 hours, or operators may change the battery when filling the fuel tank. Remote monitoring of crusher production performance, engine loading, temperature, and location is also available. These may be monitored via wireless service to a smart phone or computer.

From Heatec
Heatec says that managers of asphalt facilities in the United States and Canada are showing a remarkable response to the Recon™ monitor system that the company introduced in late 2015. Recon units are now in operation at 23 facilities and being installed at 9 others. Heatec is working through a significant backlog of orders for additional units at press time.
The Recon system enables plant personnel to remotely monitor the live status of asphalt heaters and asphalt storage tanks at their HMA plants. Operators use this information to avoid unwanted shutdowns due to heating problems. And they keep close watch on asphalt use and inventories to better plan tank refills.
The Recon monitor shows heater alarm status, hot oil temperatures, asphalt tank temperatures, tank liquid levels and tank mixer on-off state. Operators can use a smartphone, tablet or PC to access the system.
Chris Cook, Plant Superintendent at King Asphalt, Pacolet, South Carolina, says he really likes the remote access that his Recon system provides. He uses his iPhone to keep close watch on tank levels and temperatures at their facility. And he looks forward to finding ways to use the historical data that the system records.

From Rotochopper
To help customers capitalize on growing opportunities in recycling markets, Rotochopper has launched a new line of industrial slow-speed shredders. The track-mounted diesel TS-2 made its debut at Expo Richmond in Richmond, Virginia. The TS-2 is an aggressive dual-shaft shredder designed to pre-process stumps, commingled C&D, railroad ties, and other forms of mixed or contaminated waste.
Boasting simplified operation, streamlined maintenance and rugged reliability, the TS-2 features an open shredding table, allowing dirt, stones and other abrasives to pass. Paired with easily accessible routine maintenance areas, the TS-2 avoids the complicated upkeep often associated with slow speed shredders.
In addition, Rotochopper and Key Knife have launched the Key Knife Chipper knife package, which allows horizontal grinder owners to chip and grind with a single machine. The chipper knife package is a bolt-in option that works with the same patented replaceable mount rotor for the Rotochopper B-66 and B-66 E. This chipper knife system makes it simple to diversify into chipping applications without a complex conversion kit or a second machine.
To switch from grinding to chipping, the operator does not need to swap the whole rotor drum or assemble a complex overlay onto the grinding rotor. Instead, he swaps the grinder tooth mounts with chipper knife mounts.
This system uses patented Key Knife® technology to minimize knife replacement costs. Key Knife shipping inserts are indexable (reversible). By loosening the knife clamp bolts, the operator can flip the knife to use a second chipping edge.

From Stockpile Reports
Stockpile Reports, an inventory management system companies use to measure volume and tonnage of materials via drone, plane and iPhone-based measurement tools, released its new Verified Measurements feature June 13, 2016.
Stockpile Reports’ Verified Measurement feature gives a confidence score to each one of the stockpile measurements at construction and aggregate producer sites. When stockpiles are measured, there can be all kinds of measurement risks. Vegetation growing on the pile, standing water, equipment obstructions and more, all can cause big errors in a company’s inventory numbers. The Stockpile Reports system automatically highlights those risks, so companies can always have the insights they need to know whether to have crews do some pile cleanup and re-measure. Companies can almost eliminate write-offs and costly budget overruns.

From Systems Equipment
SYSTEMS Equipment has announced the release of the 1292 Material Temperature Capture at Time of Load, the newest companion product to the company’s Windows-based loadout system, the WIN-LC3000. Product conception was spurred by feedback from both producers and end-users in the asphalt industry with a common objective—to have an efficient way of measuring and documenting the temperature quality of hot mix being used for any given job.
The 1292 assembly consists of a PLC and two modules to be mounted in the control center (with an optional enclosure), as well as a probe and housing assembly that is mounted to each loadout silo (or drum, if used with the blend system).
Asphalt plants employing this technology have the unique position of being able to measure and document asphalt temperatures at time of load, as well as adjust temperatures with better precision for ongoing production based on feedback from pavers applying the product. This quality assurance discipline provides accountability throughout the asphalt “chain” for any given job. Some state- and federally-funded projects also require this temperature measurement to ensure that the asphalt mix meets code-specific requirements.
The 1292 includes a single infrared probe protected by an enclosure measuring approximately 4.5 inches high by 3 inches wide by 3 inches deep. One probe per silo is required. When used in tandem with the loadout system, the active end of the probe is mounted to the loadout silo frame and directed toward the truck bed. A small air valve incorporated into the enclosure prevents debris from attaching itself to the end of the probe and skewing the reading. As loading proceeds, the probe measures the temperature of the newly loaded asphalt mix. The temperature reading is both stored in the loadout database and printed on the driver’s loadout ticket.
The 1292 assembly can also work cooperatively with the blend system, capturing material temperature as the asphalt mix exits the drum. Due to the thick metal housing on traditional temperature measurement units, getting an accurate reading takes time as the heat must work its way through the housing and to the probe. “With the 1292 assembly, the reading is almost instantaneous,” Fred Axmear, software engineer at SYSTEMS Equipment Corporation, said. “This is particularly helpful with small batches, and also improves reaction time when temperatures need to be adjusted because feedback is both quick and accurate.”
He added, “By installing the 1292, operators now have a much greater level of control over the quality of their hot mix. Having the ability to document mix temperatures at time of load also gives them an added level of assurance and documentation for jobs with higher requirement levels, such as federal highway projects. Their bases are covered.”
