What we've got here is 'a failure to discharge!'

A test that tells you when you need to tackle a powder-flow challenge
Powder products — such as flavorings, flours, pharmaceuticals and nutraceuticals — are part of a broader group of materials called “bulk solids” that can range from micron- to millimeter-sized particles.

Should we repair or replace this boiler?

Before deciding, consider any demand load changes, and what type boiler is best
It goes without saying that steam plays a vital role in chemical and other type processing plants, and that having a reliable, cost-effective and safe boiler is essential to good operations. As a facility ages, it eventually gets to the point where it’s time to choose between upgrading the current boiler or getting a new one.

Wrecked steel mill coupling renewed for half the cost of replacement

Bore ‘replaced’ with splined-in insert — correct diameter restored, original rating maintained
When the bore on the rigid half of a high-torque steel mill coupling was badly galled during a maintenance teardown, an East Chicago, Ind., mill put the damaged part in the plant’s boneyard. However, engineers at Kop-Flex developed a clever solution that saved almost half the cost it would have taken to replace the part.

Because they are so common, routine leaks and spills can sometimes be missed when facilities review safety hazards. But these small “inconveniences” are a leading cause of slip-and-fall incidents.

The motor itself can also be more energy efficient

Brushless PM motor technology more efficient over broad operating range, author says; use of less costly, readily available ferrite magnets
NEMA Premium efficiency induction motors are considered by many to be the standard for integral horsepower, general-purpose, AC induction motors. While these motors raise the bar for energy efficiency, continuing improvement is both possible and cost-effective.
