Siemens Siemens Energy & Automation, Inc. launched the Siemens Milltronics brand MBS belt scale that it describes as a reliable and economical belt scale that provides dynamic weighing information for process indication. A basic, modular, medium-duty scale, it is designed with an accuracy of plus or minus 1.0 percent. It features high-performance, parallelogram-style aluminum, strain gauge load cells to provide instant response to vertical loading. It is said to be unaffected by uneven belt loading, high belt speeds, and horizontal forces such as belt drag or idler friction. The new belt scale does not have a cross bridge, which reduces material buildup and allows universal fit on most conveyor widths. WOHWA Designed for poorly flowing material (such as wet sand) or coarse particles with a low discharge rate, WOHWA Distribution Inc.’s metering belt is available in belt width ranges between 16 and 48 inches, depending on required delivery rate. The height of the material bed can be adapted to the discharge rate or the material and can be adjusted manually. The metering belt is available as a flat belt, corrugated sidewall belt, or flat belt with trapezoidal sections aligned along the edges. For abrasive material, the conveying areas can be lined with wear-resistant material. Options include a dust cover and discharge box. Kemper Equipment Kemper Equipment heavy-duty radial stackers and conveyors describes as “built to last.” The systems feature a 36-inch deep truss, with structural tubing throughout to resist corrosion and buildup while transporting aggregates. The company offers standard length stackers and conveyors, as well as customized systems. Stackers can be designed to handle a fixed height discharge or can telescope for varying stockpile heights. Standard features include the following: electric power travel; chain drive; OSHA-approved, full-length walkway; and OSHA-approved handrails. The stackers feature a folding design with a fifth wheel connection. Martin Engineering

Schenck Designed as a single feeder operator interface, Schenck’s new OP1 provides users with operation, calibration, trending, and basic diagnostics in one easy-to-use system. Start-up is simplified by using an integrated tutorial that walks the operator through each step. A graphical color touch screen display contains the latest in HMI technology and multi-level password protection allows a supervisor to select and protect read or write parameters for operator access only. The interface can be packaged in a panel-mount unit with the Disocont control or configured independently in a NEMA 4 type enclosure, which allows for a remote-mount interface. Other features include 4 MB of flash memory, four global function keys, and a lighted LCD display. ASGCO
Kanawha Scales & Systems Kanawha Scales’ belt scales are designed to be installed on new or existing conveyors with minimal downtime. Using conveyor-mounted carriage assemblies and state-of-the-art electronic weight indicators, the scales are suitable for weighing applications in the most demanding industrial environments. The Series 20 Belt Scale System allows the operator to control feed rates to crushers, mills, screens, and other processes with plus or minus 0.5 percent accuracy. Smalis Conveyors
Optibelt Optibelt offers its V-belts, designed to satisfy inspection requirements related to fire and electrostatic product characteristics, for safe use in underground mines. The belts underwent extensive testing by Deutsche Montan Technologie (DMT), a fire-protection center in Dortmund, Germany, and were certified for fire safety. Electrostatic testing was performed by the EXAM BBG, a product testing and certification center for explosive protection in mining. Belts are available in sizes starting at 487 mm (19 inches) and up. Cyclonaire Corp.
A&R Aggregate Equipment, LLC Designed and built in the mid 1970s, slightly more than 100 Spiral Clean Pulleys were built and sold during that era. Since then, many of the pulleys have been in continuous use and performed with little maintenance. The company reports that it offers great tracking ability, runs smoothly, and stalls less frequently than other pulleys. At the request of current equipment owners, the pulleys are once again being manufactured in the Michigan and Alabama areas. Superior Industries Superior Industries debuts the industry’s first bilingual PLC automation package, installed on TeleStacker conveyors. The easy-to-use touch screen PilePro automation system will have a standard program that provides the customer with English and French options. Systems are capable of building partially or fully desegregated stockpiles in windrows or conical piles. Simple instructions allow for quick and accurate adjustments to the radial arc distance, extension distance, and radial incline distance. Richwood

The BCi belt scale, from
Martin Engineering offers the Martin
Boco Self-Adjusting Skirting, a belt edge sealing system
that automatically maintains sealing pressure at the sides
of a transfer point to keep material on the belt and to
prevent loading zone spillage. The skirting is said to float
on the belt and to self-adjust. Supported on pressure arms
between two steel plates, the system’s rubber sealing strip
rises and falls with fluctuations in belt travel to
automatically maintain an effective seal as it wears. The
company says the skirting system has the lowest belt edge
requirement of any commercial skirtboard sealing system and
provides an effective seal with as little as 1.25 inches of
free area outside the conveyor’s steel skirtboard and each
side of the belt.
To help producers meet increasingly
demanding specifications,
ASGCO designed its Skalper MDX
pre-cleaner for high-speed, high-tonnage conveyor systems in
above-ground and underground mining. It has heavy-duty
urethane blades to withstand abusive conditions. They mount
against the head pulley to provide continuous cleaning. The
adjustable 6-inch blade segments can be replaced by removing
two bolts. ASGCO says the most unique feature on the Skalper
MDX is the torque cam action lever. The impact force creates
torque that rotates the blade allowing it to self-adjust to
the angle of the belt. The company says this is ideal for
removing high volumes of carryback with minimal blade wear.
It also prevents the mounting tube from bending because it
allows the tube to rotate and to absorb the shock.
Smalis Conveyors rolled out its news
line of road portable radial stackers featuring the
hydraulic powered “radial walker” axle-and-wheel assembly.
The patent-pending design includes dual wheels with
four-wheel disc brakes and enables the user to quickly and
easily switch the wheels hydraulically from the towable
position to the radial position. By employing the disc
brakes and hydraulic power, these stackers are said to be
able to “walk” themselves from side to side, therefore
eliminating the need and cost of a separate power travel
mechanism. Currently, the systems are available in belt
widths of 30 and 36 inches and lengths of 90, 100, and 110
feet. 
The PortoVeyor Bulk Bag Unloader from
Cyclonaire Corp. is said to provide efficient pneumatic
transfer of material from bulk bags into silos that are
normally serviced by pneumatic trailers or railcars. When
normal trailer or rail service is available, the portable
system can be easily moved out of the way. It allows for
safe handling and cleaning of any free-flowing dry bulk
material shipped in bulk bags. Ruggedly built, the
PortoVeyor can be customized with optional hoists and
lifting frames to support and unload all sizes and styles of
bulk bags without slippage or spills.
