Aggregate producers can test and track screen performance to ensure maximum screening productivity by accessing the Orbit+ mobile app and wireless accelerometer from Deister Machine Co. According to Deister, the wireless accelerometer is portable, small enough to fit in a pocket and uses powerful magnets to securely attach to the screening unit to provide accurate, precise measurements. When connected to the mobile app, Orbit+ can conduct multi- and single-point tests, as well as log and share results. Producers can quickly and easily conduct vibration tests and monitor machine speed, stroke, amplitude, angle of throw and side motion. They can also view orbit, waveform and spectrum data, as well as log test records and maintenance schedules. 

The HVC-1000 expands Elgin ’s horizontal vibratory centrifuge product line with a more compact, cost-effective unit. It joins the HVC-1400 and HVC-1500 machines, offering Elgin’s dual-mass, two-mode suspension technology. The suspension system provides isolation of vibration forces from centrifuge and from plant structure. With low vibration transmission, no rubber isolation elements are required under the machine. HVC centrifuges incorporate reliable sump lubrication for rotation bearings and grease lubrication for vibrator motors. According to Elgin, HVC centrifuges offer user-friendly, above-floor maintenance and enhanced guarding. Both 50-Hz and 60-Hz operation is supported with no need for variable-frequency drives. In addition, processing options are broad due to the availability of screens in a single-piece, self-supporting style and multi-piece screen/basket systems. Screens are offered in multiple aperture sizes and two different screen angles, Elgin adds.

The new polyurethane Niagara Drop Guard wear liners from Haver & Boecker Niagara  provide total cross beam protection for Niagara vibrating screens and can be installed on a screen deck in just 15 to 20 minutes, the company says. To install, users simply drop the polyurethane liner over the cross beam – with no adhesive or tools required. Replacing the liner requires just lifting out the old product and dropping in a new one, reducing downtime, Haver & Boecker Niagara says. Drop Guard replaces the company’s current Zip Guard and Snap Guard options, and producers can access a variety of other liner options from the company to further protect critical vibrating screen components such as feed boxes, discharge lips, side plates, tension rails and bar rails.

Conn-Weld Industries understands every application is unique, and it designs to ensure maximum efficiency to meet challenges. Conn-Weld says the sand plant sizing and rinsing screen pictured at right is a prime example. The 6-ft. x 20-ft. SD horizontal comes with Conn-Weld’s G-Master 2000 mechanism, a heavy-duty deck support frame, and with AR and rubber liners installed on the feed box and discharge lip to provide for long wear life. Specifications are met with a manifold and spray system, an H-beam mounting base and an A-frame motor stand. Conn-Weld says quality paint standards are achieved by shot blasting components to near white metal, two-part epoxy undercoat and customer-specified two-part epoxy topcoat. 

Monitoring vibrating screening equipment and issuing a warning before a catastrophic failure can save tens of thousands of dollars in unscheduled outages, Syntron Material Handling  says. Using smart technology, Syntron generates warning messages through a phone app or iPad about a customer’s screening equipment by integrating devices such as temperature and stroke measuring sensors, vibration monitoring devices, and oil level indicators to predict oncoming conditions such as bearing failure or possible structural damage. These messages are immediately distributed to maintenance and operations to schedule repairs to prevent lost output downtime.
