  • Understanding Gravimetric Blender Accuracy & Payback

    Accuracy is one of the least understood aspects of blending. The differences between batch and continuous blenders, how blend accuracy is calculated and controlled, which blender type is more accurate, how much accuracy is really required, and how payback is calculated are discussed here.

  • AUXILIARIES: Batch Blender with See-Through Mixer

  • Tune Up Your Gravimetric Blenders

    Gravimetric blenders provide for the most consistent and accurate blends of plastic materials and additives, but even these seemingly simple machines need some TLC after a long production run.

  • Materials Handling: New Equipment Emphasizes Efficiency & Value

    Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.

  • Continuous Gravimetric Blender Feeds Multiple Powders

    Process Control Corp., Atlanta, has brought out its first continuous gravimetric powder blender.

  • NPE 2006 News Wrap-Up: Materials Handling: A Host of Refinements and Updates

    NPE 2006 held no revolutionary changes in dryers, blenders, feeders, loaders, or conveying controls, but widely adopted improvements make the newest models easier to use and maintain—and easier on the budget, too.

  • What to See at NPE 2006: Materials and Parts Handling

    Dryers, feeders, blenders, loaders, metal detectors, level sensors, mechanical and pneumatic conveyors, silos, bins, pumps, filters, valves, box fillers, bag dumpers, and materials-handling control systems constitute one of the biggest categories of products on display at NPE.

  • Resin Dryers: Which Type Is Right for You?

    Processors today face bewildering choices of at least five basic types of dryers, whose capabilities are subject to conflicting claims from equipment suppliers. For the buyer, the most basic questions are: How much drying is needed for the job and which dryer types are up to the task?

  • K 2004 Wrap-Up on Recycling & Scrap Reclaim: Turn Trash to Cash with New Compactors, Shredders and Grinders

  • NPE News Wrap-Up: Materials Handling

    The big show in Chicago presented more new loaders, feeders, blenders, and conveying controls than you could count. They’re more flexible, easier to maintain, and easier to control. Many are web-enabled, and some are lower in cost.

  • The Right Way & The Wrong Way To Add Materials Conveying Capacity

    Whether you're expanding your current plant or consolidating operations and moving equipment from one location to another, you will need to make sure that your material-handling system delivers the productivity you expect.

  • In Auxiliary Equipment--Small Is Big

    Auxiliary equipment is shrinking to catch up with a growing market for small precision parts. Dryers, loaders, blenders, grinders, and chillers have all dropped in size for accuracy and fast product changeovers.

  • Putting Blender Accuracy To the Test

    When you look at competing claims for gravimetric batch blenders, the issue is accuracy. Virtually all makers of the equipment claim similar accuracy, but the numbers appear to mean different things to different people. You need to know what counts for you and how to test accuracy with your own resin and regrind.
