Solves spillage problems
Flexco says its new Flex-Seal skirting is designed to fully seal the loading zone, preventing spillage leaks, controlling dust emissions, and guarding against costly belt damage and mis-tracking. An angle plate positions the skirt rubber to the belt so the internal spring-back tension in the rubber creates the seal without damage. Low contact pressure on the belt prevents belt grooving and excessive cover wear to prolong belt life.
Combination screen debuts
GreyStone is introducing a combination fine-material screen at this month’s ConExpo-Con/Agg show. The new 36-inch Aggre-Dry FMW sand dewatering unit combines a fine material screw and dewatering screen to produce sand and gravel products with a moisture content as low as 8 to 13 percent by weight. It uses only 30 horsepower to wash and dewater up to 100 tons per hour.
New telescoping conveyor
Masaba Mining Equipment has launched its new Magnum Telescoping Conveyor. The 36-inch by 150-foot unit features Masaba’s proprietary track technology, hydraulic shift axles, and PLC operation. The patent-pending track design is said to provide constant positive traction and improved long-term durability. The hydraulic shift axle are said to provide a seamless hydraulic shift from free wheel road travel to high-torque stacking. And the company’s PLC operation features simplicity and high quality desegregation piles, with four fully functional programs allowing users to choose their stockpiling preferences.
Long-lasting fine wire
W.S. Tyler has introduced Ty-Ger Wire, a high-carbon industrial wire available for high-wear screening application. The company says this hard steel wire was traditionally available only in larger diameters, but it has developed a patented process to create a small diameter wire that is high-wear, tear-resistant, and extremely elastic. The company says Ty-Ger Wire has up to two times the tensile strength of stainless steel and up to four times the strength of basic steel.
Larger solid-body breaker
Atlas Copco has extended its line of solid-body hydraulic breakers with the rollout of the SB 552. The 1,149-pound attachment is designed for carriers in the 9 to 15 metric ton class. It requires an oil flow of 17.2 to 30.4 gallons per minute at a pressure of 1,450 to 2,180 psi. It delivers up to 1,080 blows per minute. Its one-piece design contains all integral parts in the same iron alloy casting for strength, and the unit is said to have fewer moving parts than competing units.
Fintec has unveiled a new track-mounted impactor that combines its expertise in designing track-mounted mobile crushers with the impact-crusher expertise of its new parent company, Sandvik. The new 1440 features a Sandvik PR301D impactor with a fluid clutch drive and a 440-horsepower engine. Fed by a two-deck pre-screen, the crusher is a four-hammer, open-style rotor. The unit has an operating weight of 49.8 metric tons and is about 51 feet long. It is designed for throughputs of 300 to 350 metric tons per hour.
