  • Waylay weight woes

    Production managers, quality control managers and maintenance engineers alike have encountered weigh cells that never worked properly. Why? Why have so many switched from a supposedly high accuracy load cell solution to old fashioned level probes or sight glasses? This article touches on the worst culprits for problems and how to avoid them.

  • Avoid trouble with slurries

    Handling slurries (a mix of solids and liquids), should be based on experience and experiments, not theory. Much of the knowledge obtained from pneumatic conveyors and fluidization systems can be used in understanding slurries.

  • CAGI to verify compressor claims

    The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.

  • Mind Mixer Mechanical Design

    While most mixers can provide a long service life — for instance, some are still operating after more than 30 years — mechanical problems can shorten life or even break parts. In this article, learn about all the mechanical problems that may befall your mixing equipment.

  • Avoid confusion with air injection for fine powders

    Fine powders often need air injection to increase flow rates to an acceptable level. With entrained or injected air, powders flow like water, but when deaerated, the extremely low flow rate may be confused with a hang-up or arching condition.

  • Process manufacturing: No transfer required

    As the pharmaceutical industry has matured, concerns about the safe handling of drug compounds during the manufacturing process have increased. To meet exposure limits and protect batches from any kind of contamination, the industry’s need for improved containment has increased.

  • Properly introduce solids into a flowing gas stream

    Particulate solids are often required to be introduced into a flowing gas stream. If not done correctly, introduction of solids into the gas stream can lead to impingement of solids on the pipe, resulting in erosion of the pipe in the area of the solids introduction.
