Abrasive materials can wreak havoc on conveying systems and Carbo Ceramics’ application is a perfect example. To read the full case study, click here. The Eufaula, Ala.-based manufacturer was performing weekly repairs on the worn elbows of its ceramic bead plant. The company replaced all 12 elbows in their system with HammerTek® Smart Elbow® deflection elbow technology. The Smart Elbow units have lasted at least four years compared to the one- or two-week lifespan of their …

Even innocent-looking PET poly pellets can wreak havoc on conveying systems when the perfect storm of variables come into play. Such was the case with Schmalbach-Lubeca’s Blythewood, SC plant. Manufacturing plastic bottles for use in the beverage industry is a 24/7 operation, and line shutdowns were proving to be an expensive problem. Similar to many manufacturing and production facilities, the Blythewood plant used conventional long-sweep elbows as part of the conveying system, moving the pellets …

To comply to federal sulfur dioxide emissions standards, PECO Energy Company’s Eddystone plant employs a scrubbing process using magnesium oxide (MgO). The material is pneumatically conveyed from storage silos to a mixer before being sprayed into the exhaust stacks. Producing electricity is a 24/7/365 operation and the MgO system must always be running. Simply put, elbow failure is not an option. In reality, however, the standard 316L stainless pipe elbows that made up the pneumatic …

Montgomery County’s North Incinerator plant outside Dayton, Ohio, uses finely powdered limestone in its three incinerator units to bring sulfur dioxide emissions (a by-product of combustion) in line with EPA air pollution standards. Each day, approximately 18,000 pounds of the highly abrasive, dusty material are conveyed through the facility using long-radius stainless steel sweep elbows. Long considered the industry standard, these conventional sweep elbows are critical components in any conveying system. Failures at these crucial …

Breweries like Miller Brewing Company’s Fort Worth, Texas facility demand efficient use of space — and for good reason. The production of beer from grain to glass requires moving barley malt and water (the two primary ingredients) from storage vessel to mash tun to boil kettle to bright tank. Plagued by maintenance and housekeeping problems stemming from a single automatic diverter in the grain upload system, Roy Marin, staff engineer at the facility, decided to …

When you’re in the business of manufacturing and handling abrasive materials, line plugs and worn-out elbows (and the resultant downtime and losses in productivity) are troublesome and costly realities. That was exactly the case for Dave Goodwin, Plant Maintenance Superintendent for the Scarborough, Ontario plant of Fiberglas Canada. Goodwin’s plant suffered through as many as 20 wear-related clogs per year — always occurring at the same two refractory elbows in the conveying system connecting the …

Even the most seemingly innocuous materials can be become destructively abrasive when moved pneumatically — maintenance manager Al Husni of ACRO Extrusion Corporation saw it firsthand. A Wilmington-based company, ACRO produces vinyl window systems and extrusion. PVC resin, a key component in vinyl formulations, was moved pneumatically at such a high rate (34,000 pounds per day), traditional sweep elbows were wearing through as often as every 14-21 days. These line failures were costly. Repairs and …

Essroc Materials Inc. produces nearly 400,000 tons of cement annually using two 400-foot rotary kilns. The wet-process cement in Frederick, Md. was continually plagued by dust produced as a natural by-product of cement kilning. How much dust? Try 120 tons of dust every 24 hours. A portion of this dust is sold for use in various industrial and agricultural applications, but the majority must be moved pneumatically and recycled back through the kilns through a …

With a daily volume exceeding 80 million gallons of water treated, the Alexandria Sanitation Authority knows a little bit about the need for efficiency and just how catastrophic line breaches can be. To control pH, the facility uses more than 500,000 pounds of pelletized lime each month. Trucks deliver the material to 70-foot silos via a pair of four-inch lines. Due to its abrasive nature, pelletized lime was wreaking havoc on the conveying system by …

Hammertek’s Smart Elbow® deflection elbow saves space, time and money. If you’ve ever read this blog, you know that. Practically every article we’ve posted has highlighted the tangible benefits realized by companies across multiple industries once they’ve made the switch to Smart Elbow products. The combination of a small footprint and innovative design make the Smart Elbow deflection elbow an ideal solution for high-wear, high-volume environments.

PECO Energy Company’s Eddystone plant employs a scrubbing process using magnesium oxide (MgO) pneumatically conveyed from storage silos to a mixer before being sprayed into the plant’s exhaust stacks — a process necessary to keep the plant in compliance with federal sulfur dioxide emissions standards. Whenever the coal-fired plant is generating electricity, the MgO system must be operational. Elbow failure is not an option.

Many manufacturers of abrasive materials fight a losing battle in their conveying systems. The root cause of constant pipeline problems along the entire manufacturing process is the abrasive material being conveyed, wearing through conventional sweep elbows at an alarming rate. Chromalloy’s Drilling Division was experiencing problems every 90 days. The companys Houston plant produces ground barite (barium sulfate), an abrasive compound used in commercial drilling operations. The high-density material was wearing through 4- and 5-inch …

Fiberglass is an especially abrasive material. RheTech Inc.’s long-sweep elbows were being worn away little by little until the inevitable happened — an expensive breech in the conveying system. The result was costly: product spillage, line shutdowns, and a substantial impact on productivity. Gary Wright, RheTech’s director of Plant Engineering, was convinced there was a more efficient and cost-effective way to keep the conveying systems operational.

Commercial breweries operate under some extremely tight quarters. Storage vessels for raw ingredients (especially malted barley), fermenters, bright tanks and chillers occupy large footprints on the production floor. Facilities managers are continually seeking out ways to increase production yields and efficiencies without losing square footage for the people operating and maintaining equipment. When the grain upload system at  Miller Brewing Co.’s Fort Worth, Texas plant needed a complete redesign and equipment upgrade, staff engineer Roy …

When wastewater treatment plants experience blowouts, cleanup is costly. Of course, there’s the cost of labor and materials, but there’s also potential fines as well as the obvious health risk and safety concerns. The Upper Occoquan Sewage Authority (UOSA) wastewater treatment plant in Centreville, VA, handles nearly 30 million gallons per day to provide potable water to more than 300,000 residents in northern Virginia. In order to raise the pH of the water to levels …

Regular readers of this blog know that in case after case, HammerTek’s Smart Elbow® deflection elbows have eliminated wear-related leaks in pneumatic, liquid, slurry and steam conveying lines across multiple industries. When manufacturers install Smart Elbow products to address line failures, they see benefits almost immediately – less line down time, drastically reduced maintenance and cleanup costs, and significantly increased productivity. By eliminating leaks of EPA-regulated materials common in many manufacturing processes, Smart Elbow deflection …

Silica aggregate, a key component in industrial flooring products produced by Stonhard Inc, at its Ft. Wayne, IN plant is an incredibly coarse and abrasive material — and the company was seeing first-hand how mercilessly it was wearing down components in its pneumatic conveying lines. According to Greg Sosenheimer, plant manager, 82,000 pounds of the material moves through the system each day, and the ceramic elbows Stonhard used to direct and funnel the flow of …

When you’re in the business of manufacturing and handling abrasive materials, downtime and expense caused by line plugging and rapidly wearing elbows are almost inevitable. That’s what Dave Goodwin, Plant Maintenance Superintendent for the Scarborough, Ontario plant of Fiberglas Canada, believed. Goodwin’s plant suffered through as many as 20 wear-related clogs per year — always occurring at the same two refractory elbows in the conveying system connecting the batch house and the furnace hall.
