Picking the right screen media for your operation can make a significant difference in meeting production goals.

Compass Wire Cloth says its aggregate screen division supplies stock and custom fabricated harpwire, finger, non-binding, urethane, and rubber screens for the aggregate industry. The company also offers related products, which include clamp rails, channel and skirtboard rubber, screen bolts, and test sieves.
Some screens offer unique shapes and designs which are said to increase production.
The Western Group offers anti -blinding and anti-pegging Z-Slot screens in three configurations — straight Zs, Z Diamonds, and Z Herringbones — to best match the application. All three are manufactured with either polyurethane strips or wire spacers.
Hoyt Wire Cloth says its new Hi-Rise screen offers improved open area and screening action because of its shaped, rather than round, wire. According to the company, it can carry heavier deck loads because it is up to 55 percent stronger than traditional screen cloth panels. The screen is available in oil-tempered and full-hard stainless-steel wire with openings from 3/16 inches through 2 inches.
Self-cleaning screens can help increase production by reducing downtime due to blinding, pegging, or clogging.
Major Wire says its Flex-Mat 3 self-cleaning screen media employs independently vibrating wires that better separate material, virtually eliminating blinding, pegging, or clogging and increasing product throughput by up to 40 percent over traditional woven wire or polyurethane panels. Flex-Mat 3 is available for modular or tensioned screen decks.
Buffalo Wire Works says its Clean PFX Series self-cleaning screens allow a more efficient use of available screening surface area and, thus, greater production of spec product. According to the company, the polyurethane strips allow individual wires to vibrate independently from one another at variable frequencies, preventing material build-up, and the formed lap prevents contamination or premature failure.
Modular screen media offers users the ability to replace only the worn or damaged portion of a screen, thereby reducing replacement costs.
Sandvik says its modular rubber screen media is a cost-effective solution, allowing only the worn out modules to be replaced instead of the entire screen. The modules are made of hard-wearing rubber material developed to give long life and require minimal maintenance. According to the company, modules stay in place for optimum material flow and can be moved around to maximize wear life.
Linatex says its Snapdeck line of modular screen media provides increased throughput and longer wear life over competitor modular systems. Its easy-snap attachment system makes retrofits and replacements simple. The screens are available in a variety of urethane or rubber compounds.
Polydeck Screen says its new modular, PolyWeave screen panel design series features multiple surface shape options, all intended to improve material stratification and more effectively drain water than traditional flat surface panels.
GeoSonics/Vibra-Tech offers a complete line of seismic monitoring units for use in the aggregates industry. Its SSU series seismographs feature an ISEE-compliant external geophone with a microphone, internal memory, easy-to-read LCD, heavy-duty stick and twist metal connectors, long-life rechargeable lead-acid battery, two independent threshold alarms, imperial/metric support, flexible user interface for on-site programming, free analysis software, and one-year warranty.
Orica says its uni tronic blast box BB310R is a remote blasting solution. The remote blast box can be placed in proximity to the blast pattern and can communicate via radio modem to the firing control box, which can be positioned at a point of safety up to 6,500 feet from the blast pattern, providing increased safety for personnel and equipment. The unit is compatible with the company’s existing uni tronic Scanner 110 and uni tronic Scanner 120 equipment and is equipped with a Bluetooth module allowing easy download of scanned detonator details.
