August 2009 – RollOuts
Martin Engineering’s upgraded insertable dust collector features improved filters and a smaller footprint while controlling airborne dust at belt conveyor loading points. The smaller filter’s mesh-like material filters better and lasts longer, says the company, while consuming less energy than conventional filter bags. The unit’s pulse cleaning system sends a short pulse of air through the filter to dislodge accumulated material. No tools are required to change the filter.
Customizable rotary valve
Aerodyne says its Rhino H Rotary Valve, used for metering dry granular materials in manufacturing processes, provides a smooth, predictable flow of material without the problems that plague other valves not designed for abrasive materials or not able to be customized. The valve’s vanes have hardened tips. Tight tolerances between shroud and rotor vanes minimize material entry that can cause wear. The valve is available with four, six, or eight vanes; standard sizes are 8, 10, 12, and 15 inches.
State-of-the-art diesel engine
Volvo Penta says it 16-liter TAD1643VE is a completely new, state-of-the-art, variable-speed diesel engine built on the company’s in-line-six platform. It boasts a high-tech fuel injection and air charging system with low internal losses for exceptional combustion and low fuel consumption. Available as a factory power unit or loose engine, the company says it is designed for easy, economical installation and is well balanced to produce smooth, vibration-free operation with minimal noise levels. Service and maintenance points are easy to access. The engine is equipped with piston cooling and is also fitted with replaceable cylinder liners and valve seat/guides to ensure maximum durability and service life.
Tier 4/Stage III engine technology
John Deere Power Systems says it has new technology to meet the stringent Interim Tier 4/Stage III B mobile off-highway emissions regulations. The company developed an exhaust filter consisting of a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF) that it will add to its Tier 3/Stage III A PowerTech Plus engine platform. According to the company, the DOC reduces carbon monoxide, hydrocarbons, and some particulate matter. The downstream DPF traps and holds particulates remaining in the exhaust stream where they are eventually oxidized through a process known as regeneration. The new engines will be released in January 2011 when the new Tier 4/Stage III B regulations become effective.
New generation submersible pump
Grindex says its new generation submersible heavy-duty drainage/sludge pumps are ideal for construction, tunneling, mining, and other industries. Features include “Smart” Motor Protection that prevents pumps from single phasing, overheating, and backward rotation; and an air valve that allows the pump to run completely dry without damage. Designs range from 1.9 to 140 horsepower and deliver between 155 and 5,000 gallons per minute.
