Over the years, the science of conveying has developed components that make material movement as efficient, safe and low-maintenance as presently possible. This equipment can make or break operational profitability, and below we've provided a wide sample of systems and components that, in sum, provide aggregate operations with just about every solution imaginable.

The Belt-Way conveyor belt scale features in-motion weighing technology and a modular design. The company's Belt-Way controller can be connected directly to a PC or used to monitor production from a remote location via modem using Windows 98, ME, 2000 or XP. A new Belt-Way stainless steel conveyor belt scale is available for both single- and dual-idler applications. The load cell, load cell housing, speed sensor and mounting hardware have stainless steel construction and are designed to handle corrosive environments. Another product, the Belt-Way dual idler system, has two sets of load cells, doubling the size of the weighbridge and allowing the integrator to “see” the material for twice as long, thus decreasing the expected margin of error to plus- or minus-0.25 to 0.50. The dual idler routinely is used for extremely fast moving belts or applications.

The HotSpotIR system samples 100,000 conveyor temperature points per second, according to Ametek Land. The compact, high-resolution system measures temperatures ranging from 68° to 482° F (20° to 250° C). Each scan samples 1,000 points and then the scanner outputs a signal of the highest temperature sensed, updating it with the next scan 1/100th of a second later. Temperature measurements are continually sent to a dedicated processor that can trigger an alarm or signal the conveyor operator to take corrective action. A durable sapphire window provides reliable protection for the system's optics and a built-in laser targeting system aids alignment on to the target. The unit can be positioned under or above the conveyor. The company says that the unit installs easily.

Argonics' Eraser belt-cleaning system is built around the company's patented Perma-Torque tensioning system and equipped with a 7.25-inch-tall V5 Raptor blade. Other available primary cleaners include the portable Micro Eraser, the heavy vibration-resistant Eraser HD, the Super Eraser for high-tonnage belts and the channel-mount Super HD Eraser. The manufacturer also offers secondary cleaners: the XTC reversing model and the Super G, which is designed to minimize belt maintenance. Tertiary cleaners include the V-Max X-Plow with an adjustable down pressure system, the E-Max V-Plow and the V-Max V-Plow, which uses downward force to scalp belts clean.

The Bolt ‘N’ Go flight system from 4B Components is a new assembly method for drop-forged and round-link conveyor chains. The system allows assembly onsite or in the shop, and with precise calculated flight bending forces. It is forged chain and round-link chain compatible. Plastic flight (high-density polyethylene or nylon) and steel flight (drop-forged chain only) options are available. No welding is required.

Cross-Belt Separators from Bunting Magnetics Co. provide continuous removal of ferrous contaminants from material on open conveyors. The unit's high-density permanent ceramic plate magnet reaches deep into the product flow and captures elusive scrap, even from fast-moving belts. The cross-belt design creates a large coverage area whether the unit is suspended parallel, or at right angles, to the conveyor. Tramp iron falls from the unit's cleated belt as it moves the captured metal debris beyond the magnet's face and out of the magnetic field.

The 36- × -150-foot Magnum telescoping conveyor with track technology has a new design that incorporates hydraulic shift axles for field setup without chains, according to Masaba Mining Equipment. A standard four-wheel drive system is used to provide positive traction in the field and a swing axle design is intended to yield a stable footprint. A simple PLC works in conjunction with variable-speed wheel drives help to desegregate piles. Four programs allow users to choose their stockpiling preference.

The Schenck Process BEMP single idler belt scale is for weighing and totalizing continuous flow rates of bulk solid materials up to 15,000 tph in a modular package. The unit is said to mount to conveyor frames with only four bolts, whether the conveyor uses 18- or 60-inch-wide CEMA idlers. Because the scale use two NTEP-approved single-point load cells and the Intecont MS Integrator, accuracies of plus or minus 1% of totalized weight reportedly are possible. Fieldbus connections to a process supervisor also are possible.

Crisp Industries Inc. builds bulk material-handling systems, which rely heavily upon overland conveyors, transfer conveyors and stackers. The manufacturer assists customers in constructing heavy-duty conveyors for rail loading and unloading facilities. The accuracy of certified belt scales for rail loading and unloading systems can be accomplished through the use of specifically designed hardware components, according to the company.

The Negotiator self-aligning return roll from Douglas Manufacturing is designed for belt-training applications where conventional self-aligning idlers have not been able to help with belt tracking. The self-cleaning frame design helps prevent material buildup by shedding carry-back from the return side of the belt. A three-roll design is intended to form a support bed that cradles the belt and more efficiently react to the pressure of the side guide rolls. Rubber discs help to shed material and prevent material buildup and UHMW side guide rolls are said to have the lowest possible coefficient of friction available to help prevent belt damage. The rolls can be used for bi-directional belts and a low-profile design suits tight applications. The mounting brackets can be adjusted to within plus or minus 1 inch for an additional tracking aid. This can be achieved while the conveyor is running.

Claudius Peters Technologies can design a longitudinal stockpile with a travelling tripper or shuttle and a PHB Someral portal, semi-portal or side-type reclaimer for storage. Once the material is stockpiled, it is reclaimed in successive passes along the pile. With flexibility in reclaiming depth and unit traveling speed, the reclaim rate can be adjusted as required. PHB Someral's portal reclaimers are suitable for stockpile widths exceeding 198 feet (60 meters) at a wide range of reclaiming capacities. For limited-space situations, semi-portal reclaimers provide maximum storage capacity. A side reclaimer, designed for spans of less than 99 feet (30 meters), is designed with both rails along one side of the pile.

Martin Engineering offers its Pit Viper belt cleaner to remove sticky sand and wet fines on belts from dredges, sand screws and other sand-processing operations. Its one-piece blade reportedly contains about 20% more urethane than comparable pre-cleaners for longer service life. It is designed to allow “one-pin, no-tool” blade replacement; the blade is dropped into place on the reinforced steel mainframe and secured with a wire lock pin. The cleaner fits head pulleys up to 16 inches (406 mm) in diameter and belt widths from 12 to 42 inches (300 to 1,067 mm). Belt coverage can be 2 inches (50 mm) or 6 inches (150 mm) less than belt width to match the width of the material on the belt.

Flexco's electric belt cutter is for all types of belting including natural rubbers and solid woven PVC and fabric plied belts. The tool is made with heavy-duty stainless steel and is available in two sizes. The EBC1 electric belt cutter is capable of cutting a rubber belt up to 1 inch (25 mm) and up to a maximum 360 P.I.W. (630 N/m) on PVC belts. The EBC2 cuts rubber belts up to 2 inches (50 mm) and up to a maximum 1,140 P.I.W. (2000 N/m) rating on PVC belts. The tool also allows for longitudinal and angled cuts. The steel blade is protected by a spring-loaded guard and the sealed ball bearings that support the belt during cutting are incorporated to provide nearly friction-free feeding of the cutter on the cutting surface.
