Dewaters plant sludge
McLanahan Corp. has obtained exclusive rights to market Matec Machinery’s HPT Plate and Frame Filter Press in the Americas. The company says Matec’s use of high pressure technology (HTP) allows the press to work at pressures of up to 300 pounds per square inch and handle even the most difficult, high-clay-content sludge. The Matec Press is said to function without use of flocculants and does not require a full-time operator to monitor feed density, flocculant dosage, or belt conditions. McLanahan says the unit also eliminates the need for settling ponds.
Bigger track-mobile plant
Telsmith has expanded its QuarryTrax line of track-mobile crushing plants with the introduction of the T16060, a primary impact plant designed for high-capacity production up to 800 tons per hour. The plant features Telsmith’s PA6060 primary impact crusher, which boasts a massive solid rotor set on oversized 220 millimeter, wide-series bearings. The large rotor allows the unit to crush 40-inch stone or concrete slabs.
Compact portable plant
Pump Vacuum Systems has developed a different way to produce sand and gravel using the company’s PVS Jet Pump. It created a portable plant that can produce multiple products while washing the material. The plant uses a grizzly screen to remove oversize, then moves sized material into the pump, where it is washed and conveyed either to a de-sander or a velocity box, then separated into final products. The company says its first plant is producing 300 tons per hour using one wheel loader to charge the plant and load trucks.
Self-dumping dust collector
Farr Air Pollution Control has introduced a new self-dumping hopper that simplifies the disposal of dust captured by cartridge-style dust collection systems. Farr says the hopper, available in one or two cubic-yard capacities, is easier to use than conventional barrels or collection drums and is recommended for a full range of dry mists, including those that must be reclaimed or recycled after the collection process.
New vibrating screen
W.S. Tyler has rolled out its new TYCAN HSG T0Class vibrating screen which allows the stroke and amplitude of the vibration to be adapted to product requirements quickly and easily, without new parts. The company says its new technology allows screen media to be “easily blended, modified, and exchanged, optimizing wear life versus open area.”

They also get more hydraulic horsepower and larger-diameter hydraulic cylinders. The CX350B and CX700B now feature regenerative hydraulics on the boom and arm, as well as the bucket curl, speeding digging cycle times.
Lippmann-Milwaukee is touting its new 5062 jaw crusher as a replacement for a gyratory primary crushing station, describing it as a “massive,” high-capacity unit designed to hold up in the most demanding hard rock mining operations. Lippmann says that for the price of one gyratory installation, aggregate processors are successfully installing two of 5062 Jaws.
More powerful drill string
Rockmore says it developed the new XR32 thread design to provide underground drillers with a stronger, more powerful drill string. The XR32 connection is said to provide stability at the thread end, reducing stress on the thread connection. Its design provides stronger rod support, increased rigidity, and added strength to minimize rod bending due to complex rock formations or uneven surfaces.
Loader training simulator
Simlog has introduced what it says is the world’s first PC-based wheel loader simulator for training quarry and mine operators. The simulator puts trainees at the controls of modern loader and includes digging and interaction with a simulated off-highway truck. It is designed for skills assessment, skills development, and refresher training for both new and veteran operators.
Biodiesel blends approved
Case Construction Equipment has approved the use of B20 blends (20 percent biodiesel, 80 percent petroleum diesel) for most of its construction machinery. The company approved B5 blends in 2006. Case has published a chart matching its models and engines to current biodiesel recommendations.
Impactor gets new features
Stedman has added two new features to its Grand Slam secondary horizontal shaft impactor. The new Crush Plus grinding path system creates a third crushing chamber to maximize one-pass product yield, minimize oversize, improve material soundness, and produce highly cubical product. The Max-Yield automated apron adjustment system maintains gap setting adjustment for aprons and the grinding path, improving one-pass yield and reducing changeover downtime.
Production-boosting roller bearings
Emerson Industrial describes its new Sealmaster Mounted Spherical Roller Bearing as an advanced, double-row design that improves load capacity and speed capabilities in aggregate conveyor operations. The bearings feature pillow blocks that contain high-capacity, double-row spherical roller bearings designed to carry high radial and combination loads. The series is said to have a higher basic dynamic rating (BDR) than competing models with a similar cartridge design.
Ruggedized time-clock system
TimePilot has rolled out a time and attendance system designed from the ground up for construction-related applications. The weatherproof design can be mounted on walls, posts, or the side of a truck. Employees clock in and out by touching a key-sized iButton to the clock. The clock reads the iButton, identifies the employee, and records the time.
Smaller, updated screen
Powerscreen has developed the H5163R scalping and screening plant as a smaller, updated version of the 6203 plant introduced earlier. The new unit can handle materials up to 10 inches and produce up to 600 tons per hour of high-specification products.

‘Promising’ hybrid research
Volvo Construction Equipment is touting new research that shows diesel-electric hybrid technology can reduce fuel consumption and CO2 emissions by greater amounts than previously thought.
“We are facing the very real prospect of fuel savings up to 50 percent, significant performance increases, and a reduction in CO2 emissions in the order of millions of tons a year,” Volvo CE’s Arvid Rinaldo told Aggregates Manager’s Kirk Landers and a group of international business journalists in June.
Volvo unveiled its L220F Hybrid last March, projecting fuel savings of up to 10 percent depending on application. Further product development has improved fuel usage even more – in particular, an integrated starter generator that allows the engine to switch off when the machine is motionless and instantly switch on when the engine is needed. Volvo expects to begin deliveries of the L22F Hybrid late next year.
Indeco is replacing its UP-series breaker line with the new HP series, which boasts increased hydraulic efficiency across the line. The company has also introduced innovations specific to each size class, including a slimmer, lighter casing for mini breakers.
