Conveyor Idler Bearing Isolator Increases Reliability And Safety While Reducing Downtime And Power Consumption

Inpro/Seal Company has announced its new Belt Conveyor Idler/Roller Bearing Isolator. The result of direct customer request, input and feedback, continuous R&D and extensive field testing and trials, this product was designed to increase productivity, save energy and increase safety in coal mining, ore mining, aggregate and related applications that use belt conveyors in bulk material handling applications. Before the advent of the Belt Conveyor Idler/Roller Bearing Isolator, users had to deal with outdated sealing methods, in particular elastomeric seals to protect idler bearings. Small, spring loaded, contact seal, elastomerics are tiny plastic devices that make contact and rub on the exterior of the idler roll while operating. Elastomeric seals are widely used because they are cheap and because there has not been anything better available–until now. As a contact seal is prone to failure and needs constant maintenance, the entire bearing protection system is somewhat precarious. And when an elastomeric seal quits working, undesirable things happen, much of it without warning.

A huge industry problem
Belt conveyors are in service, around the world, working 24/7 to “trough the belt” or transport bulk materials in coal mining, ore mining, aggregate, hard quarry and related applications including; concrete, asphalt, fertilizer, salt, recycling, wood, pulp and paper, electric utility, grain, construction, agricultural, steel and general industrial. These belts are typically supported by three conveyor rollers, or idlers, positioned at intervals as close as three linear feet. One roller is horizontal and other two are positioned on either side, at an angle necessary to carry the burden. Depending on the specific application, they operate above and under ground and may extend for many miles over mountainous terrain, roads and streams. There may be as many as 10,500 bearings and bearing protection devices on the conveyor rollers per mile of run. In the mining industry it is estimated that each mine has 3-4 miles of conveyor with idlers strung out the entire length of the belt. When an idler fails, it is most likely the result of bearing damage caused by contaminants (dust or moisture) entering the bearing environment. Chances are the plastic has failed by wearing out and has grooved the shaft or has burned to a crisp at the point of contact. Once an elastomeric seal fails, contaminants are drawn into the housing, where they condense and contaminate the lubricant and cause the bearings to fail. The end result is a seized roll, belt damage or worse. The idler can burst open, and if it does, metal-on-metal contact can cause a fire. To counter this, most mining operations employ greasers that work around the clock trying to keep idler bearings lubricated in an effort to make contact seals work. But, because lip seals carry a 100% failure rate, eventually users will have to deal with catastrophic belt failure no matter what they try.

A welcome solution
Inpro’s Belt Conveyor Idler Roller Bearing Isolator is custom-engineered to suit individual applications. It is easy to install because it conforms to existing clearances, housings and bearing patterns. It can be retrofitted to any existing manufacturer’s top side and return frame assemblies in any belt width or troughing angle for any brand of conveyor. It is available in any idler configuration, including: CEMA B, C,D and will fit any idler type including: transition, impact, troughed, training, return belt, flat carrier, impact, rubber cushion return, self aligning, self aligning return, offset center roll, picking and feeding, unequal length troughed, wire rope, wire rope return, low profile, “V” return idler, variable trough, rubber disc, ceramic,
two, three and five roll garland, live shaft and side guide conveyor idlers.

1206_problemsolvers_img3Magnetic Oil Filtration Technology

According to its manufacturer, the Halex Coil can enhance the performance of an existing oil filter. The key to its effectiveness is the powerful rare-earth neodymium magnet with which it is constructed. The magnetic field draws particles that are too small for the filter to catch, resulting in cleaner oil.Moreover, the Halex Coil easily attaches to the outside of an existing oil filter. Filters are engineered to maintain flow while lubrication is passed through small holes. Smaller holes mean finer contaminates are trapped. The coil is a filter that performs better than its micron rating without changing flow-rate and without intruding on internal systems. It’s simply a different way to trap more, as it traps 40-90% of iron that would otherwise pass through the existing filter medium. By bonding and “piggybacking,” it traps 20-60% of nonferrous contaminates. This can help extend equipment life and service intervals, improve element efficiency and fuel economy and reduce downtime, emissions, soot and wear.

1206_problemsolvers_img8Dry Ice Cleaning Of Machinery Without Disassembling Or Moving It

Kärcher Industrial Products has introduced a dry ice blaster, a highly effective and mess-free method for in-place cleaning of machinery. The new IB 15/80 Dry Ice Blaster uses compressed air to propel tiny dry ice pellets at supersonic speeds so they flash freeze and then lift grime, paint, rust, reins, mold, asphalt and other contaminants from a broad range of surfaces. Moreover, the pellets quickly dissipate into the air so there’s no messy wastewater, solvents, sand or other media to dispose of, only the soiled contaminant that is easily swept up or vacuumed. Dry ice blasting is growing in popularity because it completely eliminates the need to disassemble or move machinery before it’s cleaned. The labor savings is significant, reducing to a few hours what used to take days to do. Furthermore, dry ice blasting cleans in crevices that can’t be reached by hand or via other cleaning methods. This technology also is extremely environmentally friendly. The CO2 pellets are non-toxic and non-hazardous, making them safe for the environment, equipment, the workplace and, especially, employees. The IB 15/80 operates on 120V electricity (5 amps) and uses a blasting pressure of 44 to 230 PSI. Compressed air requirements range from 150 to 300 CFM.
