Bridgestone Americas Off Road Tire, a division of Bridgestone Americas Tire Operations, LLC, Booth N-2501
Bridgestone’s V-Steel J-Traction (VJT) radial off-road tire features a computer-optimized center block that minimizes vibration levels, reducing friction between the center block and the ground to improve wear resistance and tire life. The tire has a specialized self-cleaning tread design and non-directional tread pattern to maximize tread volume and traction in all directions. The tires are available in five sizes — 17.5R25, 20.5R25, 23.5R25, 26.5R25, and 29.5R25.
Cardinal Scale Mfg. Co., Booth C-7733
Cardinal’s EPR+ Plus truck scale features interconnecting load blocks and receivers for an efficient, no-bolt installation. The scale arrives on site ready for the pouring of concrete — no rebar or other materials are required. Its Con-Lock system design allows concrete to flow through the I-beams and lock into place. Mounting brackets are flush mounted to allow for pit-type applications.
Caterpillar, Inc., Booth N-1913
Caterpillar says its new G Series 775 off-highway truck will be the first Cat machine to go into production with a Tier 4 Final emissions solution. The company says emissions reduction technologies are integrated into the machine’s design, allowing the truck to perform at peak production while reducing emissions by approximately 90 percent.
Crusher wear studies
Columbia Steel says the information provided in its ‘wear studies’ will help plant operators and their suppliers select the right wear part designs and alloys for any given job. The studies provide real-world equipment data — feed and discharge information, throughput rates, change-out records, and measurements on worn parts.
Energy-saving electromagnetic vibratory feeders
Eriez says its heavy-duty electromagnetic vibratory feeders have an energy-saving intermeshed AC/permanent magnet drive that makes them workhorses. The feeders require minimal maintenance and feature an electromagnetic design that has no moving parts, eliminating the need for lubrication. The feeders are available in nine models with capacities to 850 tons per hour.
Nitrogen gas-assisted breaker
Doosan says its DXB170H hydraulic breaker features nitrogen gas-assisted operation for improved efficiency. The 3,572-pound breaker delivers up to 600 blows per minute and is designed for use with excavators in the 18- to 28-metric-ton weight range. Other features include a patented hydraulic dampening system said to prevent blank fire damage, an energy recovery system said to increase strike power using energy generated by piston rebound, and a patented main valve design said to reduce hydraulic pressure peaks.
Software tracks equipment maintenance
HCSS says its equipment maintenance software program, Equipment 360, enables companies to manage their entire maintenance operation, thus lowering costs. The program tracks and stores itemized cost history for each piece of equipment. Its work-order management system provides a framework for capturing labor and parts costs; mechanics can enter their time directly into the system.
Compact, self-contained submersible pumps
Godwin Pumps will display two hydraulic, submersible, compact, self-contained Heidra pumps — the HS80HH and HS150HH. The HS80HH is a top-discharging pump with a 3-inch pump end and diesel-driven power pack. It features a flow up to 450 gallons per minute and 325 feet of total dynamic head with a simple throttle adjustment. The HS150HH features a 6-inch pump end, diesel-driven power pack, flow and head requirements up to 1,250 gallons per minute, total dynamic head requirements up to 460 feet, and the ability to handle solids up to 1 3/8 inches in diameter.
Cone crusher offers site flexibility
FLSmidth says its Raptor XL500 cone crusher features a large feed opening, high-pivot-point crushing action, and a wide crushing stroke. Its large 59.06-inch head diameter and eccentric motion is said to allow it to accept feed up to 25-percent larger than crushers with less throw and similar head diameter. The crusher’s 148-inch diameter and 106,500-pound weight offer flexibility for multi-site crushing operations.
Track-mounted impact crusher
Wirtgen says its new EVO Series of Kleemann track-mounted, mobile impact crushers constitutes the next generation of impact crushers and represents a genuinely new evolution for the entire plant spectrum in terms of performance, economic efficiency, and equipment longevity. The new EVO concept matches refinements for all individual components with a new material flow concept which eliminates all restriction to the flow of material throughout the entire plant — the discharge chute is 4 inches wider than the inner width of the crusher, and the discharge belt is 4 inches wider than the discharge chute.
Remote printer terminal increases truck throughput
The Libra remote printer terminal is designed to increase truck throughput by keeping the driver in the truck, according to the company. The high-speed printer features a document presenter that holds the delivery ticket for the driver and, if not taken, retracts it into an internal box. A heat shield keeps the printer cool in direct sun, and an internal heater keeps it warm in freezing temperatures. A motion-activated light illuminates the unit when the enclosure is opened.
Kiosk offers automated ticketing
JWS says its Apex RFID kiosk provides an integrated solution for automation and optimization of bulk materials facilities when used in conjunction with the Apex AutoID module. The kiosk consolidates the PC, electrical connections-I/O, vehicle identification, touch-screen user interface, and network connections in a self-contained, rugged outdoor enclosure for attended/unattended bulk materials ticketing. The unit weighs 114 pounds without the sunshade (168 pounds with the sunshade) and is 20 inches wide by 24 inches high and 12 inches deep.
Screen media innovations
Major Wire says its Flex-Mat 3 high-performance, self-cleaning screen media technology is available in a tensioned version as an alternative to traditional woven wire, and as a modular version designed to replace polyurethane and rubber modular screen panels. Flex-Mat 3 is said to provide up to 30 percent more screen capacity than woven wire and up to 50 percent more screen capacity than polyurethane and rubber panels. Independently vibrating wires are said to increase product throughput by up to 40 percent over traditional woven wire or polyurethane panels by increasing open area and eliminating blinding, pegging, and clogging.
Fixed, modular, and mobile sand plants
McLanahan says its Ultra Sand Plant can produce as many as three separate products without a classifier. The company says a combination of cyclones and dewatering screens results in a drier construction sand product, so less usable sand is lost to waste. The company offers its plants in fixed, modular, and mobile configurations for washing, organics removal, and fines recovery.
Alternative to wet washing
Sturtevant says its Whirlwind Air Classifier provides an alternative to wet-washing minus-200 mesh fines from crushed stone. The classifier’s self-contained design incorporates an internal fan and rejecter-blade classification system. Material is belt conveyed by gravity into and out of the classifier and discharges from one single outlet. Rotating selector blades control the particle size of the fines removed by the air. Benefits include water conservation, reduced land requirements, elimination of settling ponds and dredging, and a secondary saleable fine product.
Portable crushing and screening plant
The new Terex Cedarapids CRC380HLS portable crushing and screening plant’s design is said to allow the cone crusher to be constantly choke fed, maximizing production. The high-lift screen and cone hopper overflow system allow a large head of material to build up, force feeding the cone crusher. The large cone hopper and overflow chute buffer feed variations and prevent material from backing up to the screen. A gross throughput of up to 1,200 tons per hour is possible, according to the company.
Higher energy per blow
Tramac says its new V4500 heavy breaker was specifically engineered to provide a higher energy per blow. The breaker features blank-firing protection to prevent metal-on-metal contact, a pressure regulator valve to prevent overpressure and accidental overflow, reinforced suspension to absorb vibration, an automatic pressure regulator to ensure constant operation despite variation in flow or temperature, an automatic frequency adaptation system, increased striking from an energy recovery feature that captures rebound energy for the next blow, and an automatic greasing system.
Versatile impact crusher
Universal Engineering says its VersaCap primary impact crusher is designed to be versatile and reduce quarry shot limestone. Features include reversible hammers with a protruding leading edge for longer wear life at higher reduction ratios and adjust-on-the-fly capability. The “Shot-Rock” primary is available in three sizes.
Transforms fines into saleable material
W.S. Tyler says its new Haver palletizing disc transforms wasteful fines into a transportable, saleable product. The disc offers variable side-wall height, speed, and inclination. Its direct-drive technology works without a gear box and hydraulic coupling, eliminating the maintenance required for traditional components. The efficiency of the drive is said to minimize energy losses, reducing total energy costs up to 5 percent.
