Single-Idler Belt Scale

Providing continuous in-line weighing for a variety of products in primary and secondary industries, the Single Idler Belt Scale (MSI) suits a wide range of tough applications — from extraction in mines, quarries and pits to power generation, iron and steel, and chemical processing. Accordingly, the MSI belt scale may be used for monitoring such diverse products as sand, flour, or coal.

The belt scale's patented use of parallelogram-style load cells results in fast reaction to vertical forces, ensuring instant response to product loading. It is thereby able to provide outstanding accuracy and repeatability, the manufacturer notes, even with uneven loading and fast belt speeds. Operating with a microprocessor-based integrator, the MSI indicates flow rate, total weight, belt load and belt speed of bulk solid materials on a belt conveyor. A speed sensor monitors conveyor belt speed for input to the integrator.

The belt scale is installed in a simple drop-in operation and may be secured with four bolts and an existing idler set, secured to the dynamic beam. With no moving parts, maintenance is kept to a minimum, with only periodic calibration checks required. Siemens Energy & Automation, Inc., (+1) 215-646-7400, ext. 2592

Horizontal Shaft Impactor

Designed to increase profits by maximizing production, developers note, the Mega-Slam Primary/Secondary Horizontal Shaft Impactor handles feed sizes beyond the range of conventional secondary impactors. Five Mega-Slam models produce a cubical product, eliminating the need for primary reduction equipment in some crushing operations. The largest model, the Mega-Slam 6460, is capable of delivering from 550 to 700 tph with a 61-in. × 46-in. feed opening that handles limestone, sand and gravel, and asphalt applications.

The Mega-Slam models feature a solid rotor said by the manufacturer to be contoured and computer-designed for maximum efficiency. A positive breaker bar holding device with buried wedges minimizes wear as well as breaker bar installation, removal and indexing time. The solid rotor weldment is stress-relieved, balanced and ultra-sonic tested. Reversible manganese monoblock aprons and interchangeable side liners reportedly make this impactor one of the strongest in the aggregate market.

Mega-Slam models are designed for durability with optional 3-in.-thick replaceable secondary apron breaker plates, a standard rear apron spring bridge assembly to assure accurate product control and interchangeable housing liners made of 2-in.-thick hi-chrome or alloy steel. Maintenance is easy with a hydraulic pump allowing one-person opening of the hinged rear housing. Side doors, double rear doors and a large roof hatch offer easy access for inspection and adjustment of gap settings. Stedman, (+1) 800-262-5401 or 812-926-0038

Wheel Washing System

Suitable for quarries, construction and demolition sites, coal-fired plants, landfills, solid waste sites, new housing and other contaminating sites, the Wheelwash Rhino System is compact and portable as well as easy to maintain and to erect, the manufacturer contends. To meet increasingly strict regulations in North America requiring wheels and tires to be free of mud, dirt and other contaminants before leaving a site, the portable wheel washing system is suitable for short-term or temporary projects. No excavation is necessary; the Rhino system requires only a concrete/asphalt pad or crushed stone base. Water recycling is included, with the settlement tank/weir system recycling 90% of the water.

Featuring compact, heavy-duty construction requiring minimal maintenance, the system is modular and conveniently assembled on-site, arriving in two halves, then bolted together and lowered into position. All that is necessary to start operations after set-up is access to water and electric. Cleaning is accomplished with a multitude of high-pressure jets providing extensive spray patterns to cover all surfaces of tires, wheels and undercarriage, utilizing a horizontal centrifugal pump in cast-iron housing fitted with a cast-iron impeller, a single mechanical seal and coupled with a 22-Kw (30-hp), 2900-rpm, TEFC electric motor.

Operation consists of running vehicles through the system without drivers leaving the cab. As a vehicle approaches, an inductive loop sensor activates the high-pressure spray system, whereupon the vehicle is driven over a patented angle grid system, causing tire treads to spread and vibration to knock-off mud and debris. Upon exiting, vehicles are driven over another angled grid system that helps shake off excess water. Although wash time normally lasts from 15 to 45 seconds, depending on severity of vehicle condition, the duration can be regulated up to three minutes by changing the settings at the electronic control panel, housed in the heated/lighted pump house.

Analog Truck Scale

For weighing highway vehicles during low-to-moderate traffic applications, the 7461 Truckmate truck scale combines a weighbridge design with economical analog load cells. The manufacturer notes that the modular steel deck scale offers fast and easy installation as well as reliable weighing at an affordable price. The 7461 weighbridge features an orthotropic design with reinforcing ribs that extend the length of each module. The ribs increase the deck's rigidity by distributing loads over a larger surface area as they form an airtight chamber that eliminates rusting from within, also resisting damage from metal fatigue due to no welds in the highest stress areas.

Using economical analog technology without extra mechanical components that can wear or become misaligned, the load cells feature an integral rocker pin suspension designed to maintain a vertical position as traffic moves over the scale. Constructed of stainless steel, the load cells are hermetically sealed for superior moisture protection. The Truckmate line of scales, which can be installed above ground or in a pit, has been tested extensively using several processes, including tandem-axle load simulation for evaluating life cycle, the manufacturer reports.

Reversible Impactor

To enable both crusher-hammer faces to wear evenly and eliminate the need to manually turn anywhere from six to 27 hammers weighing from 65 to 455 lbs, the reversible impactor allows for reversing the rotation of the rotor assembly. Hammers must wear evenly if they are to maintain proper output size. The company's reversible impactors are suitable for crushing limestone, fertilizers, potash, coal, steel mill slag, petroleum coke, ceramics, tungsten carbide and other materials. Reduction ratios as great as 35-to-1 can be achieved, developers note, with no chance of overcrushing and with minimum generation of fines. The company's reversible impactors are said to require less power than an ordinary hammermill to crush the same amount and stand far less chance of plugging. Offered in 26 sizes and four configurations, they accept maximum input sizes up to 4.5 in. in the smaller models and up to 16 in. in the larger models. Pennsylvania Crusher, (+1) 610-544-7200

Ultrasonic Level Transmitter

The new KSONIK III ultrasonic level transmitter is capable of continuously measuring the level of liquid and solid applications over spans of 197 ft (60 meters) at a high degree of accuracy (0.25% at full span). Electronic circuitry provides instant variable gain and power control of the transmitted signal, accounting for precise level measurement of such materials as foams, corrosive liquids, solids, grains and powders. The transducer of KSONIK III, which usually consists of one or two transducers and a single transmitter, is fitted to the top of the silo or tank facing down towards the material to be measured. The microprocessor in the transmitter fires an electronic pulse that is converted by the transducer to an acoustic pulse, which travels to — and is reflected back from — the stored contents. The transducer then converts this energy back into a signal and stops a counter in the microprocessor to determine the distance. Powerful software removes false echoes, and the electronic filter removes ambient noise.

While ultrasonic level control has long proven itself as a cost-effective means of measuring levels under dusty (powder or granular) conditions, the precise monitoring of levels within very tall silos and large tanks has traditionally proved difficult due to false echoes and weak return signals. However, the KSONIK III overcomes this limitation by dynamically varying the gain and power settings of the transmitted signal.

KSONIK III utility and cost-effectiveness are multiplied through dual-channel capability that powers two separate transducers to simultaneously monitor levels in two different tanks or silos with 4-20 mA analog outputs. Additionally, the level detector accommodates up to five SPDT relays (each @ 5 amp, 230 VAC). Each relay can be configured to operate from either channel for a variety of control options, such as activating pumps in lift stations or sumps. Local level indication consists of a two-line, 16 character alphanumeric display. All operations are password protected.

Five touch-buttons on the KSONIK III face panel permit swift set up. Optional KSCOPE software, a multi-use Windows-based software package, also facilitates programming and bin mapping, while providing fault diagnostics via dynamic site analysis. Further promoting ease-of-use and accuracy, a 21 Point Linearizer takes into account the product being measured to provide an exact linear duplication of level. No offset curve is required for calibration.

Maximum flexibility in using the KSONIK III comes about through a choice of interchangeable transducers for applications involving large distances (60 meters), corrosive solids and liquids (strong acids and alkalines), foams, as well as extremes in temperature (-30° to 65° C) and pressure (0-50 psi). Immediately available for shipping, the KSONIK III is able to run off 120 or 220 VAC. K-TEK Corp. (+1) 866-735-5583

Conveyor Skirt Clamps

Designed for easy installation and use, the Rockline RMC1 conveyor skirt rubber clamping system requires merely welding cylindrical steel mounting pins approximately two feet apart along the outer surface of the conveyor skirt board. A specially formed clamp plate is placed on each pin, and a sliding wedge held captive in a slot at the free end of the pin swings sideways to hold the plate in place. A clamp bar (standard 1-in. × 1-in. × ⅜-in. angle) is placed across the lower ends of the plates, nesting in a V-notch formed into each plate and secured by tack welds. Skirt rubber is set in place between the clamp bar and the conveyor skirt board, loosely resting edgewise on the conveyor belt surface. Tapping the wedges to tighten or loosen the clamps helps avoid the corrosion, seizing, stripping and over-torque breakage problems associated with threaded fasteners often used in skirt clamping.

RMC1 Skirt Clamps are offered in kits of two clamp pins, two clamp plates and one 4-ft-long clamp bar. For lower cost, or extended-length transfers, Rockline Pick-A-Length (PAL) PAKs offer only clamp pins and plates to support whatever length of 1-in.-angle clamp bar the user supplies. One PAL PAK (two pins/plates) is recommended for every four feet of bar length.

Standard clamp plates are 7 in. in height to accommodate a wide range of skirt rubber widths. Optionally available for smaller or portable conveyors and those with tight clearances, closely fitted transfers or chutes, shorter 5-in.-high RMC1-LS (Limited Space) clamp plates accept standard skirt rubber from 4 in. to 6 in. high.
