Digital Diagnostic Junction Box

Unlike standard analog resistance junction boxes, the NTEP-approved iQUBE digital diagnostic junction box is said by developers to increase the performance of any multi-cell application, including truck and railroad scales, tank and hopper scales, and floor scales. Reducing scale downtime and ensuring accuracy with continuous monitoring, iQUBE's diagnostic features alert technicians to potential scale malfunctions via troubleshooting data. LEDs change from green to red to indicate a suspect load cell and its specific location for speedier diagnosis and repair. Additionally, the operator can enable the Cell-Emulator feature, which compensates for A/D drift failures or connection errors. iQUBE's intelligence compensates also for the use of different capacity load cells. Suitable for new or retrofit applications, according to the manufacturer, the system combines connectivity, diagnostics, data acquisition, performance, economics and future migration paths for any multi-cell scale system.

Conditioners

A line of heavy-duty and explosion-proof air conditioners is designed to resist corrosion and heat in harsh industrial, marine and military environments. Suitable applications cover a wide range of industries/locations, including oil refineries, coal and coke plants, foundries, and crane cabins. The manufacturer notes that its product line offers the first off-the-shelf air conditioners able to withstand hazardous conditions and built standard to cool throughout the entire range of ambient temperatures — up to 131°F (55°C), as compared to the normal 95°F (35°C), and down to 32°F (0°C) or an optional -40°F/C — without modification or electronic controls. Featuring cabinets constructed of 316L stainless steel, units meet NEMA 4X and IP56 standards. An anti-corrosion epoxy is applied and baked onto all condensers and evaporators. Fins on the condensers and evaporators are spaced wide apart (no more than 10 per inch) to prevent clogging; dirt passes right through. Condensers stay dry because fans do not throw water on them, eliminating any dangerous combination of corrosive gasses and particles in the air. On-the-shelf configurations include Through-the-Wall (Window), Split, and Roof Mount. All models can be modified to Class I (Groups B, C, or D), Class II (Groups E, F, or G), and Class III, Divisions/Zones 1 or 2 locations. Brooklyn Severe-Duty Equipment Corp., (+1) 718-643-0606

Reverse-Air Dust Collector

According to the manufacturer, “Big Round Filter” is designed to outlast and outperform other baghouse dust collectors by combining heavy-duty construction with an improved cleaning mechanism and other high-performance features. It reportedly provides high-efficiency, high-volume collection of wood, grain, metal, mineral and other dry dusts generated during powder and bulk handling processes, mining and quarry operations, metalworking and heavy industrial applications. The reverse-air dust collector features a ⅜-in.-thick metal, domed tank head roof to eliminate rust-through problems. The domed roof is combined with an all-welded housing of seven- and 10-gauge metal that will withstand 25-in. w. g. pressure. The self-contained cleaning system uses a rotating arm with a minimal number of wearing parts for reduced wear. Additional features include: a perforated inner cone that reduces can velocities for high filtration efficiency and provides a fire safety function by allowing water from sprinklers to enter the cone, if needed; a large bladder and service platform for easy access to the clean air plenum; and, a choice of 21 standard models that accept industry standard fabric bags or pleated media.

Air Conveyor Belt Fasteners

Two more sizes of Bolt Solid Plate conveyor-belt fasteners are said by the manufacturer to offer a patent-pending, rubber-topped version that adds longer life, faster installation and reduced noise to the heavy-duty belt splicing method. Like the earlier mid-sized 190VP, smaller 140VP and larger 2VP sizes combine multiple steel top-plate fastener segments (six with 140Vp and four with 2VP) under a single-piece, vulcanized rubber topcover for installation as a unit over individual Quick-Fit bottom plates preassembled with special Piloted Bolts. When used as recommended in skived (countersunk) installation, VP fasteners shield their top plates from abrasive loads, become “invisible” to tight-fitted belt cleaners, muffle the rhythmic “clank” of plates striking return idlers, and further assure the sift-free performance of lightly butted solid-plate splicing. A ⅛-in.-thick layer of natural rubber, with 65 durometer hardness similar to most belt covers, increases the service life of both fasteners and belt-cleaner blades substantially, product developers note. For the most abrasive applications, 140 and 190 sizes designated VPMA also offer bottom plates of MegAlloy, a proprietary heat-treated steel alloy developed for two to three times the wear resistance of standard steel. The three sizes of VP fasteners accommodate conveyor belts ranging from 3/16 in. to 13/16 in. thick with mechanical-fastener ratings up to 440 PIW, or running on conveyors with pulley diameters as small as 14 in. Like standard Bolt Solid Plate fasteners, the new VP versions can form a 45° diagonal splice that operates smoothly over pulley diameters 25% smaller than the 90° minimum.

Weld Wire

Company representatives note that four years of production testing demonstrated that its 600 weld wire significantly reduces downtime and extends service life of high-pressure cement rolls. Reportedly owing to the performance qualities of the Stoody 600 alloy, one Canadian cement plant cut roll maintenance and replacement costs by more than 50%. Stoody 600 is made up of a fine titanium carbide matrix that provides high strength and excellent abrasion resistance to the high-pressure roll. The open arc alloy is available in 1/16-in., 3/32-in., and 7/64-in.-diameter wires on both 60# coils and 33# spools. Stoody Co., (+1) 636-728-3000

Wear Protection

Continual wear is one of the most costly factors in the cement industry. It occurs in pipelines, separators, cyclones, bunkers, chutes, fan housings for conveying cement, raw meal, coal, clinker and clinker dust, causing significant damage over time. Because of steady growth in the size and capacity of cement production plants, wear protective linings have become an increasingly important factor. The company provides protective linings that are universally suitable for the cement industry. These protective linings are made from fused cast basalt, available for use at temperatures up to 650° F. The addition of Kalcor zirconium corundum, or the maker's high-alumina ceramics, can provide protection for high temperatures or extremely abrasive materials. Kalcret hard compound provides flexible use and temperature resistant qualities for jointless or complicated shape component linings. The protective linings also reduce the cost of replacement parts, operational downtime, plant clean-up, and maintenance work in the cement production industry. Abresist Corp., (+1) 800-348-0717

The SureShot XP laser transmitter is designed for measurement of dry bulk solids, opaque liquids, and slurries in challenging environments, developers note. Housed in an explosion-proof assembly with screw-on, glass cover for easy access, the laser features virtually no beam divergence. Thus immune to reflections and echoes as well as “cone-up” and “cone-down” variations in the material being measured, the SureShot XP is suitable for use in vessels with complex internal structures and numerous obstructions or in tight spaces as small as two inches in diameter. Satisfying requirements for application in hazardous areas (Class I, Division 1 and 2, Groups B, C, D), the powder-coated aluminum enclosure meets IP67 or NEMA 4X, DIP ratings. The laser transmitter can measure distances from one to 50 feet (0.3 to 15 meters). All-digital design incorporates an advanced timing system and self-correcting signal processing functions geared to last pulse detection for accurate and reliable measurement of level, distance and position, even in the presence of surrounding noise, such as chemical vapors, dust, or agitator blades. Readings can be updated three times per second. As Class 1 lasers are used, no special safety glasses are required. The SureShot XP is said by the manufacturer to be easily programmed with a Palm or Pocket PC hand-held device or a desktop/laptop personal computer. K-Tek, (+1) 225-673-6100
