    Efficient Pressure Compensation Improves Weighing Accuracy in Loss-in-Weight Feeders

    Processing Magazine

    Electronic pressure compensation systems are more effective and reliable than traditional mechanical systems.

    Loss-in-weight (LIW) feeder performance is dependent on accurate weighing, which can be affected by a variety of influences, both internal and external to the feeder and feeder process. Understanding the significance of these influences is critical for achieving optimal performance, since even slight changes in the mass flow accuracy of a feeder or multiple feeders can make a significant difference in both end-product quality and raw ingredient costs.

    Hard to Handle: Switching from Manual to Automated Dispensing of Reactive Powders Improves Safety Efficiency

    Tablets & Capsules

    Many chemical and pharmaceutical process engineers are challenged by metered dispensing of reactive powders into reactors and large tanks. But dispensing difficult-to-handle ingredients in a contained and accurate method can be fulfilled and completely automated using specifically designed loss-in-weight (LIW) feeders. The combination of highly advanced weighing technology, and a contained and sanitary feeder design provides for an ideal automated method of powder delivery—without the dangers and inefficiencies of traditional manual powder loading techniques.

    “Electromobility is forcing the entire battery industry into a new way of thinking”

    Currently, there are several new developments in the battery market. Particularly in electrode mass manufacturing where line operators can use various technologies and machines. One option in production is continuous manufacturing using twin screw extruders. Battery-News asked Thorsten Stirner, Team Leader of Process Technology for Chemicals and Battery Applications at Coperion, about the advantages of this process and the requirements for switching over.

    Compounding, Rheology and Numerical Simulation of Highly Filled Graphite Compounds for Potential Fuel Cell Applications

    Polymers 2023

    Highly filled plastics may offer a suitable solution within the production process for bipolar plates. However, the compounding of conductive additives and the homogeneous mixing of the plastic melt, as well as the accurate prediction of the material behavior, pose a major challenge for polymer engineers. To support the engineering design process of compounding by twin-screw extruders, this present study offers a method to evaluate the achievable mixing quality based on numerical flow simulations.

    Comparing the life-cycle cost of a vibratory feeder to a screw feeder

    Manufacturing processes involve a wide variety of raw materials, depending on the industry, and there's an equally wide variety of feeding options available on the market to bring these bulk materials into the process. In applications where  free-flowing bulk solids need to be accurately fed to ensure an optimal end-product quality, single screw feeders are often the solution of choice. However, there are a variety of options that can get the job done besides single screw feeders, such as bulk solids pumps, belt feeders, and vibratory feeders. The feeding tool choice is generally based on various application aspects, including the bulk solid material's characteristics, the desired feedrate, hazardous location limitations, the material's  flowability, and the space available for installing the equipment.

    Food Production Facility Gets Modernized

    Bulk Solids Innovation Center Journal

    Established in 1946, Salina, Kansas-based Repco has provided the enrichment industry with ideas, services and products such as flour oxidation and maturing services, vitamin and mineral premixes, micro-ingredient dispensing systems and on-site field servicing. The division of the company that produces vitamin and mineral premix products decided to look into options for modernizing an outdated mechanical transfer system. The decade-old bucket elevator system that transferred the premixes from mixer to packaging was causing housekeeping and segregation issues, not to mention large amounts of product being lost during clean-out. Repco contacted Coperion K-Tron to look into pneumatic conveying solutions that would clean up the process and ensure the finished blended product did not segregate during transfer to the packaging system.

    Vibratory Feeding Technology Gets Sophisticated


    Free-flowing bulk-solids handling can be tricky. You need to ensure a uniform discharge while maintaining the integrity of fragile, friable, abrasive or fibrous materials. Coperion K-Tron has thoughtfully engineered a line of vibratory feeders that achieve high accuracy via patentpending technology. Chemical Processing spoke with Urs Helfenstein, R&D mechanical engineer, Coperion K-Tron, regarding what makes the K3 vibratory feeders different from other feeding technologies.

    Top quality grain handling - Artisanal bourbon distillery supports its growth with Coperion K-Tron automated vacuum system for raw materials

    Food Engineering

    The dedication of Garrison Brothers Distillery to produce artisanal bourbon in Hye, Texas, has resulted in an increase in popularity, substantial growth and a need to increase production. The distillery prides itself on producing a unique wheated bourbon using the finest locally sourced and organic ingredients, some of which are grown right on the distillery property. Keeping true to that culture, Garrison Brothers expected no less from the system to supply those raw materials to the process.

    Gravimetric feeders support Eli Lilly's advancements in continuous direct-compression tableting

    Tablets & Capsules

    Continuous direct compression (CDC) tableting offers several key technical and process advantages over traditional batch tableting processes. First and foremost, it allows the manufacturer to develop a drug product on the same equipment drivetrain that will be used for the product's final manufacture, eliminating process scale-up. CDC tableting also allows for increased quality assurance and requires less production space, which lowers utility and labor costs.
