When Miller Brewing Company’s Fort Worth, TX facility needed to make a change in its conveying system, HammerTek and its patented Smart Elbow proved the right recipe for the job.
Roy Marin, staff engineer at the facility, needed to replace a worn-out automatic diverter that switched its rail car unload line from one storage silo to another. This diverter had been a source of maintenance and housekeeping problems, and Marin wanted to replace it with a new piping panel. The trick was getting the new piping to fit into the confined space the diverter once occupied; the conventional solution, a piping manifold using 4-foot-radius sweep elbows, just wouldn’t be small enough.Read More»
The Engineers at PECO Energy Company’s Eddystone Generating Plant near Philadelphia had a problem on their hands: The scrubbing process line responsible for meeting Federal emissions standards was failing on a regular basis, causing costly cleanup, environmental and regulatory concerns.
The plant utilizes a magnesium oxide-based scrubbing process to remove sulfur dioxide – a component in acid rain – from the coal-fired plant’s exhaust. Magnesium oxide powder is conveyed pneumatically from storage silos to a mixer that mixes it withRead More»
Robert Forgione was tired of slipping and sliding his way through another pile of dry pebble line and dust, half-blinded by the cloud it had created as it spewed from a failed conveying line elbow at the Upper Occoquan Water Reclamation Plant in Centreville, Virginia.
The half-inch hole created by the mere passage of lime powder through a bend in a line, called a sweep elbow in the industry, had blown the fine powder all over the building, creating not only a gigantic, slippery mess, but hazards to breathing, above-acceptable air quality levels, and danger to sensitive electronic controls – not to mention the cost of downtime on the line.Read More»
Gary Wright may have discovered something that works better than duct tape.
Wright is director of plant engineering at RheTech Inc. of Whitmore Lake, Michigan, an industry that designs, manufactures and produces propriety thermoplastic polyolefin alloys and compounds that are sold to the transportation and consumer durable goods markets.
In 1998, RheTech opened a new plant in Fowlerville, Michigan.Read More»
Tom Sorensen had a real dilemma on his hands. And it was on his hands because it wouldn’t stay in his plant’s conveying lines where it belonged.
His problem: When your plant manufactures highly abrasive ceramic beads that are used as proppants in oil and gas exploration and drilling, how do you keep those beads from doing their destructive work inside your conveying lines?
Carbo Ceramics’ Eufaula, Ala. facility manufactures calcined kaolin ceramic beads that are used by global giants like Halliburton and Schlumberger. The beads are pumped into well bores to prop open newly induced fractures and enhance the flow of oil and natural gas to the surface.Read More»
In an environment where product mixture is critical and rapidly failing sweep elbows were causing expensive downtime and EPA fines, Al Husni had to do something.
Husni is maintenance manager at ACRO Extrusion Corporation, a Wilmington, DE plant that produces vinyl window systems and extrusions. PVC resin runs from ACRO’s outdoor silos to the plant’s mixing room at a rate of as much as 34,000 pounds per day, and the abrasive product was causing the system’s sweep elbows to fail as often as every two to three weeks. Cleanup and repair was time-consuming and expensive, and any material released to the air or the ground required documentation and was subject to federal fines.Read More»
Frequent shutdowns weren’t the only inconvenience caused by failing sweep elbows at Montgomery County’s North Incinerator plant. They also created a cleanup nightmare every time the finely powdered limestone they were conveying exploded into the air like so much talcum powder.
The plant, which serves the Dayton area, also faced hefty downtime expenses if it stayed shut down too long, Plant Manager Dave Martin said.
Powdered limestone must be injected into the plant’s three incinerators to meet EPA air pollution control standards for sulfur dioxide emissions. The pneumatic conveying system used in this process contained long-radius sweep elbows. But these elbows proved unable to withstand the lime’s abrasive action.Read More»
HammerTek’s Smart Elbow handles a hopeless situation like just another day on the job.
Chromalloy’s Drilling Division produces ground barite (barium sulfate) at a plant in Houston, Texas. Barite is an abrasive material that was causing premature wear and plugging problems with the conventional elbows being used to transport it pneumatically from the plant’s grinding mills to its storage tanks.Read More»
HammerTek’s Smart Elbows work so well because they don’t allow product to impact and erode their walls. No matter the product – from highly abrasive crushed granite to seemingly harmless sawdust – all have the ability, under high speed and pressure, to erode sweep elbows.
Time and again, the stainless steel elbows in the pneumatic conveying systems at the Pet Foods Division of Quaker Oats in Rockbridge, Ill., were wearing out prematurely – sometimes in less than three months.Read More»
A company that produces pipe was having some troubles of its own before HammerTek’s Smart Elbow solved their problem.
Rensselaer Plastics Co. of Rensselaer, Ind., produces PVC piping products for the plumbing trade, with annual sales in the $40 million range. One process at the plant uses a pneumatic conveying system to transfer resin and pellets from storage hoppers to pipe extruders, and therein lay the plant’s Achilles Heel.Read More»
