August 2008 – RollOuts
Heavy-duty grizzly feeder
Masaba Mining Equipment has launched a new 11- by 16-foot, heavy-duty grizzly feeder that includes a new self-releasing grizzly mechanism that is said to eliminate lodged rock between bars. Construction features include a hopper discharge trough line with bolt-in flashing made from steel cutting edges, a wide flange-beam constructed chassis, a three-axle chassis, and a bolt-on half-inch-thick steel bulkhead with reinforced beams on each side of the plant.
Controls spillage and dust
ASGCO Manufacturing has unveiled Flo-Control, a transfer point system for handling granular and particulate materials. The company designs, fabricates, and installs Flo-Control based on its 3-DEM chute analysis simulation program that focuses on solving spillage and dust control in loading zones. The system uses a hood deflector to control material flow as it leaves the discharge pulley, and a “spoon” design on the receiving end of the conveyor for soft loading.
Increased scalping efficiency
Terex Pegson developed the XH250 Trakpactor to increase scalping efficiency and provide a high reduction ratio in applications such as crushing concrete or asphalt rubble, or limestone with low to medium hardness. It features a four-blow-bar horizontal impactor with mono block upper apron design and a 33.4- by 33.4-inch rotor; its maximum throughput capacity is 250 tons per hour.
Mass production excavator
Kobelco’s newest entry in the 80- to 90-ton excavator class is the SK850LC Super Acera. The new machine features faster cycle times, greater fuel efficiency, and a larger bucket than its predecessor and it has four work modes for precisely matching performance and fuel efficiency to each task.
Improved installation tool
Flexco has improved its Aluminum MSRT Installation Tool. The multiple rivet-driving tool is used to assist splice installers in harsh working environments where heavy splicing equipment has to be moved on a regular basis. The primary improvement in the tool is a scalloped design of the riser plate that allows for faster, more accurate alignment of fastener strips on the anvil plate.
Improves motor efficiency
Power Efficiency has improved its three-phase motor efficiency controller by making it digital. Compared to its analog predecessor, the new model is smaller and easier to install. Used with conveyor motors, the controller optimizes energy efficiency and qualifies users for utility rebates. It extends motor life and provides soft-start functionality with electric overload protection.
New family of motors
WEG has developed a new family of three-phase motors with rolled steel bodies and cast iron endbells. The motors are available in 12 sizes, from 1 to 20 horsepower. The company says the motors are lightweight alternatives to its popular cast iron motors.
