April 2009 – RollOuts
Transportable classifier system
Buell says its new 75-ton-per-hour transportable classifier system uses a dry process to remove minus-200 mesh material to produce an in-spec manufactured sand product. The dry process allows fines to be sold as a second product. There are no moving parts, which reduces maintenance requirements. Ceramic liners in some areas provide wear resistance for abrasive materials. The company says the system requires no escort when transported and can be set up in one day.
Flow diverter valves
Bosch Rexroth’s new line of modular flow diverter valves provides flows up to 60 gallons per minute and pressures up to 5,000 pounds per square inch. Zinc-plated steel bodies and IP69-rated coils withstand severe operating conditions. The valves are available as three- or six-way single valves, with the option of creating up to 14-way flows using modular diverters. A push-button control on the handle of the directional valve lever allows precise control of the required cylinder.
CARB-approved diesel particulate filter
Paccar Parts dealers now offer the Engine Control Systems Purifilter, an aftermarket passively regenerating diesel particulate filter approved by the California Air Resources Board, for use in 1993 through 2006 Class 8 truck models. The filter is available in five different inlet/outlet configurations with either standard stamped flanges or optional machined flanges. Dimensions vary: the smallest filter weighs about 75 pounds, is 10 inches in diameter, and 38 inches long; the largest filter weighs about 125 pounds, is 13 inches in diameter, and 43 inches long.
Air-intake to exhaust aftertreatment
Cummins Inc. says its QSL9 engine platform, the next generation fully integrated air-intake-to-exhaust aftertreatment system with Tier 4 technology, reduces fuel consumption by up to 5 percent. The system also increases top-rated power to 380 horsepower with peak power rising to 400 horsepower at a lower rpm in response to very high work-load demands; and incorporates Cummins’ XPI (extra-high pressure injection) fuel system, which enables multiple injection events for cleaner combustion and improved engine response.
Detroit Diesel Corp. says its new Detroit Diesel Diagnostic Link (DDDL) interactive tool not only reads diagnostic data, but interprets it and automatically determines the next steps. A troubleshooting tree provides step-by-step diagnostics to help service technicians quickly and easily address issues.
ConocoPhillips Co. says its new Guardol ECT with Liquid Titanium, a premium tier API CJ-4 diesel engine oil formulated with liquid-titanium technology, provides enhanced engine wear protection, reduced bearing corrosion, and increased oxidation stability.
