EVO® External Wear Liner Stops Spillage On Belt Feeders
At a generating plant, 5000 tons per day of PRB coal are metered via belt feeder onto conveyors and into the plant's ten bunkers. With surge of material as railcars unload, combined with the high head pressure from the hoppers, the belt feeders suffered extensive spillage. This spillage was compounded by the worn-out condition of the chutes.
MartinPLUS® Service Techs Replace Worn Out Chutes And Skirtboard Liners
Over time, operators began to notice increased dust and spillage around transfer points on four of its 42-inch conveyors. The problem was traced to worn chutes and skirtboard liners. A worn-out skirtboard liner plate was found to be exacerbating the problem. Rather than patching the existing chutes and liners, JEC want to see if they could find a better design solution.
Transfer Point Solutions Reduce Airborne Dust At Rock Quarry
A quarry in Cedar Rapids was having trouble with fugitive dust. The Health Department was notified of severe dust being blown across the highway into a residential neighborhood. The Health Department set up a dust trailer to measure the dust particles near the residential neighborhood and findings revealed the dust exceeded code requirements.
Transfer Point Solutions Solve Fugitive Cargo Issues
A cement plant was experiencing increased costs due to fugitive cargo and dust piling around the plant’s petroleum coke conveyor transfer point. The material blocked access, degraded conveyor components and required expensive maintenance. Outsourced labor using rented equipment needed weekly downtime to clean the area, further raising the cost of operation and lowering production.
Cement Plant Needed Transfer Point Solutions
Lafarge Cement was experiencing excessive spillage from one of its conveyor belts. The material was a mix of sand and water. Every time the extractor started, a mixture of sand and water discharges and the conveyor belt could not contain the material, in its current design. Martin Engineering was called to inspect the system and recommended a complete upgrade of the transfer points.
Belt Support Products Solve Fugitive Dust And Spillage Problems
A coal plant had spillage and dust issues at two conveyor transfer points, because material was loaded onto the belts traveling 500 fpm with little control over impact or settling. The result was excessive fugitive dust throughout the facility. Inadequate chute control caused spillage to get caught between the belt and rubber tail pulley, damaging both.
Failing Rubber Seals Replaced With Martin® ApronSeal™ Skirting
A coal-fired power plant was experiencing failures of the rubber/fabric seals at the top of the chute wall on its Train Unload Vibratory Feeder. Unable to handle the powerful vibration, the thin rubber seals allowed dust and fines to spill from the chute. Workers had to clean up at least once per month, and the spillage created a potential workplace hazard.
Replacing Inadequate Equipment Improves Productivity
A coal mine was experiencing heavy spillage and system damage along the length of a main conveyor due to inadequate loading zone equipment. Impact idlers allowed excessive belt sag, causing high volumes of spillage. Dust and fines fouled idlers, and rocks got lodged between the belt and the skirt, resulting in unscheduled downtime due to frequent equipment failures and chute liner replacements.
Transportation Company Needs More Flexible, High Discharge System
To maintain leadership in self-unloading technology, CSL had set ambitious goals for the discharge systems of new ships, including simplicity, maintainability, increased load capacity, flexibility, high discharge rates and environmentally-friendly operation. In March 2001, the CSL Spirit joined sister ships Sheila Ann and Sophie Oldendorff as the newest additions to the CSL International fleet.
Martin® ApronSeal™ Skirting Contains Dust And Spillage
A copper mine in Arizona was dealing with existing skirting that was not containing dust and spillage. This fugitive material led to the need for manual cleaning/shoveling of the walkway every day. The plant even bought a temporary conveyor to help alleviate this issue. Martin installed new heavy duty Martin® ApronSeal™ Skirting on the problematic conveyor.
Transfer Point Products Improve Severe Spillage And Dust Problems
At a cement plant in Kentucky, the clinker transport system had severe problems with the escape of spillage and airborne dust in the loading zones of three conveyors. Martin® Transfer Point Solutions were recommended to stop the spillage and dust problems. To improve the clinker conveying, the plant agreed to upgrade the transfer points.
Spillage Problems Corrected By Transfer Point Redesign
A coal-fired power plant was suffering from extensive spillage and other problems. The plant’s coal-conveying system needed an extensive upgrade, including new belt cleaning systems and improved transfer point systems.
MartinPLUS® Installation Services Redesign Power Plant Transfer Points
An energy company in Lansing, Iowa was facing severe spillage problems in underground loading points. The steel structure on part of conveyor feeding system was shot. It was old and worn out. There were bows and dips in the skirtboard, and it wouldn't stay sealed. This created excessive dust and spillage in the tunnel.
Transfer Point Solutions Resolve Carryback At Kentucky Energy Plant
An energy company in Kentucky was having problems with carryback on their side-by-side transfer belts carrying coal from the central reclaim tunnel to the bunkers. They hired Martin Engineering to find a solution. Martin recommended a variety of belt support, belt sealing, tail protection and dust containment solutions as well as safety accessories.
Martin Transfer Point Products Reduce Risk Of Fire Or Explosion
This power plant had dust and spillage escaping from the coal-handling systems. To boost material-handling efficiency and reduce the risk of fire or explosion, Martin installed taller and longer skirtboard walls, new belt support systems, abrasion-resistant wear liners, and a multi-layer, low-pressure sealing system on the outside of the chute walls.
Transfer Point Solutions Increase Productivity At Container Board Plant
Bark and wood waste are used as fuel to produce heat and steam for this container board plant. A series of belt conveyors 36 to 48 inches wide carry bark to the powerhouse. The Pine Hill Mill began a program to improve its materials-handling operations and eliminate fugitive materials. The bark conveying system was the first system to be upgraded.
Cement Plant Gets Extensive Conveyor System Overhaul
Like most cement manufacturing sites, GCC Dakotah employs an extensive conveyor system to handle raw materials and move finished product. GCC determined that significant upgrades could be made on conveyor transfer points to reduce spillage and dust emissions in the South Dakota facility. The upgrade included six transfer points on four conveyors.
Installing Dust Containment Solutions at Sugar Processing Plant
A sugar processing plant in California handles approximately 10,000,000 tons of raw sugar per year through their plant. One of the transfer points was giving them trouble with spillage. They contacted Martin distributor Applied Conveyor Technology (ACT) for their recommendation. ACT recommended upgrading the transfer point with cradles, wearliner, dust curtain and skirting.
Transfer Point Solutions Result In Safer, More Productive Coal Mining
A coal mining facility in China was experiencing dust and spillage from one of its conveyors. Fugitive dust lowered the air quality, clogged equipment and had the potential to affect workers’ health. Misalignment of the belt caused piles of lost product that had to be cleaned up, reducing system efficiency and wasting labor hours.
