7153 SKF says its offerings for belt conveyors covers the full asset life cycle, and includes bearings, housings, seals, lubrication systems, maintenance solutions and reliability engineering.

Conveyors in mines, quarries and cement plants perform a tough job in harsh conditions: mineral extraction and processing creates large amounts of highly abrasive dust that can enter into machinery; mix with the lubricant inside, and cause accelerated wear and eventual failure of bearings, seals, gears, couplings and other rotating parts.

SKF design solutions for conveyors, include the SKF Three-barrier solution, housings; sealed SKF Explorer spherical roller bearings, and the new SKF Taconite seal.

The SKF Three-barrier solution is said to be an environmentally-friendly, cost-effective solution that is proven to extend service life of the conveyor pulleys. The solution provides the conveyor bearing with three layers of protection against contamination and greatly reduces the amount of lubrication required by up to 90%.

For extreme contaminated conditions, the SKF Three-barrier solution is combined with the new SKF Taconite seal to block contamination entering the housing, including high pressure water during maintenance.

“The conveyor products are just a small sample of our wide variety of solutions and services for the mining belt conveyor,” says Keith Meyers, SKF’s global industry manager mining, mineral processing and cement.
“Our aim is to help our customers build reliability into their products from the outset, and support their operations and maintenance activities in a way that minimises downtime and cuts total cost of ownership.”

    Researchers at Purdue University in the United States have developed a hydrophobic sealant that could prevent potentially damaging fluids from entering concrete pores. Paul Imbrock, founder and president of Environmental Concrete Products – the university’s spin-off company - said the firm’s Fluid iSoylator product can be used to protect new and existing concrete. "Our product is absorbed into dry concrete's pore network to create a hydrophobic barrier that prevents potentially damaging fluids from en

    A variety of issues affect accurate continuous level measurement inside cement plants. The most critical concerns are dust, heavy build-ups, low-reflective media and uneven surfaces in conical and/or air-injected silos with internal objects. Now, new frequency-modulated continuous-wave – FMCW - radar technology, combined with high signal dynamics, offers a way to accurately and reliably measure product levels.
