Aggregates Manager’s Guide to ConExpo-Con/Agg 2008
High-tonnage VSI
Impact Service Corp. will highlight its ISC Model 103-VSI Crusher during ConExpo-Con/Agg. For use in secondary and tertiary crushing applications, it features a six-shoe, 51 1/2-inch impeller table. It is said to offer tremendous tonnage capability with high reduction ratios and to produce material with excellent particle shape. The crusher can handle feed sizes of up 8 inches and produces up to 800 tons per hour. ISC’s product line is designed for ease of transport for portable applications or minimal foundation requirements for permanent applications.
Higher specification metal detector
Eriez will roll out its Metalarm MA3600, a metal detector that uses pulse induction technology to offer balanced coil detection sensitivity and performance. Engineered for installation in quarries and mines, it incorporates several key features. Higher detection sensitivity ensures that even the smallest problematic tramp metal can be detected; providing better protection for crushers, screens, and conveyor belts. The metal detector is microprocessor based with self diagnostics and fault indication as standard. Significant is the hardware and software-filtering algorithm that gives enhanced noise immunity from plant equipment such as motors, inverters, and screens. The new unit includes two models: the Eagle and the Hawk. The Hawk coil is for standard applications with a sensitivity that is typically 5-percent plus of aperture height, and the Eagle coil is used when especially high sensitivities are required, nominally 2-percent plus of aperture height.
High-reduction cone crusher
Fintec Crushing and Screening Ltd. will introduce its Fintec 1080 track-mounted cone crusher system to the U.S. market. The mobile 385 horsepower cone features high strength and capacity with high-reduction performance, all-in feed, and direct hydraulic drive to produce material of desirable shape and quality. The plant features the Sandvik H3800 crusher, developed with the Sandvik CSC (cubical shape crushing) technique to produce high quality material for tight specification standards. With a hopper capacity of 6.5 cubic yards and a maximum feed opening of 7-1/2 inches, the hydraulic-adjust crusher will allow a coarse closed-side setting (CSS) of 1/2 inch to 1-1/2 inches and a medium CSS of 1/3 to 1 inch. A level monitor controls the feed rate to ensure choke feeding, while a semi-automatic setting regulation system optimizes production and tracks liner wear. A 40-inch-wide hydraulic feed conveyor allows easy access from above the crusher for maintenance while a remote radio console controls the hydrostatic crusher drive.
Belt scale reduces installation time
Belt-Way Scales, Inc. will highlight the ease of operation and calibration among its conveyor belt scales. Design modifications to the load cell assemblies — the scale’s weighing components — have reduced installation time on both standard conveyors and low-profile portable equipment. In addition, the scale may be easily removed and installed on another conveyor, if needed. A new self-aligning weighbridge assembly and updated electronics contribute to the unit’s overall performance.
Remote weight displays
Cardinal Scale Mfg. Co. will highlight its SB-500 Remote Weight Displays, which provide a highly visible readouts as well as traffic coordination. Large 5-inch-high LED digits, 2-inch-high units, and mode provide ease of visibility during scale house and ticketing procedures. A variety of connectivity options are available including serial, fiber optic, wireless, Ethernet, or Wi-Fi, while an auto-learn mode is available for most indicators. The NEMA 4/IP65 enclosure features a built-in rain hood to protect against the elements and a stainless steel enclosure is optional.
Polyurethane products
Tandem Products, Inc., with its Rhino Hyde Division, will highlight its polyurethane products for the concrete, aggregate, and mining industries. Its products include liners for concrete batch plants, hoppers, chutes, and screening media for modular and crown decks, which include Rhinowire, Rhinogrid, as well as Rhino membranes and screens.
Compact coupler attachments
At ConExpo-Con/Agg, Miller will expand its entry into the North American market with a range of compact quick couplers and task baskets. The new quick coupler range will include three versions: mechanical, hydraulic (semi-automatic with mechanical back-up safety pin), and universal fully hydraulic (operated completely from the cab). Each coupler is designed to provide fast, on-site attachment changeover. Operation from the cab increases time savings, productivity, and operator safety. The compact quick coupler range features a universally compatible design that allows for quick operation with a greater range of attachments.
