A new 170-foot-long SuperStacker, from KPI-JCI and Astec Mobile Screens, is the company’s latest model of telescoping stacker designed to minimize stockpile segregation and increase stockpile capacity. The new system is an addition to the new generation SuperStacker product line, which eliminates the echain, thereby reducing field maintenance. It also features an updated Wizard Touch automation control system.

Grasan stationary truss and channel frame conveyors are available in 24- to 60-inch belt widths and lengths from 25 to 500 feet, complete with engineered drives and a variety of options such as walkways, covers, and support legs. The standard truss main frames are 36 inches deep and all jig welded. Truss sections are through-bolted for extra strength. For long spans between supports, 48- or 60-inch-deep trusses with extra heavy chord angles are an option. Truss frames are solvent cleaned, primed, and finished with a topcoat in standard or custom colors.

Superior Industries, Inc. says its 72-inch wide by 190-foot long TeleStacker is the highest capacity telescoping radial stacker on the planet, with rates of up to 5,000 tons per hour. Engineers developed a new, more durable undercarriage system. The FB Undercarriage is a patented support system designed with more steel for rock-solid bracing at the stacker’s most crucial stress points. The heavy-duty support rollers, which are also patented, are designed to safely guide and support the internal stinger conveyor as it travels in and out of the main frame. The rollers are designed to be load equalizing to eliminate excessive and unsafe stress on each single roller.

Nordberg LL Series mobile conveyors, from Metso, are designed to link mobile primary crushing plants to other processing stages within an aggregate operation. The mobile conveyors can follow a primary unit as it moves along the quarry face, while ease of mobility allows them to remain a safe distance away during blasts. Each unit can be moved individually or as a combination of two or three sections. The units are available with a 48-inch-wide belt and 118-foot-long conveyor or a 63-inch-wide belt and 138-foot-foot conveyor. Capacity ratings are 1,200 tons per hour for the smaller unit and 2,000 tons per hour for the larger system.
